1. The Melbourne duct-fabrication market — and why your machinery supplier being local matters
Melbourne runs one of the largest and most competitive HVAC duct fabrication markets in Australia. From the established sheet-metal precincts in the south-east through to the fast-growing industrial estates in the west and north, the city is home to hundreds of duct shops — from two-person fabricators turning out fittings to multi-line operations supplying the mechanical contractors who fit out office towers, hospitals, data centres and rail stations. Every one of those shops lives or dies on three numbers: how fast it can turn coil into finished duct, how consistently it hits AS/NZS 4254 construction tolerance, and how much labour each metre of duct costs to make. Those three numbers are decided, more than by anything else, by the machinery on the shop floor.
That is where SBKJ Group fits. We are not a reseller importing equipment and quoting from a catalogue someone else printed. We are a duct-machinery manufacturer with our office and showroom in Box Hill North, in Melbourne’s eastern suburbs. We build the automatic duct lines, spiral tubeformers, lockformers, TDF flange formers, Pittsburgh lock formers and plasma cutters, and we sell them direct to Melbourne and Victorian fabricators. When you buy a duct line from SBKJ, you are buying from a manufacturer in your own city — which changes the entire purchasing experience compared with importing a machine sight-unseen or waiting on an interstate supplier.
For a Melbourne fabricator, local is not a soft marketing word. It is a hard commercial advantage that shows up in four places: you can come to Box Hill North and watch the actual machine run before you buy; you get the fastest delivery in the country because the machine is already here, not on a boat or a cross-country truck; install, commissioning and operator training are done by a Melbourne-based team on your own floor within the week; and when a line needs service or a spare, the engineer and the part are one suburb over, not one country over. Each of those is worth real money on a busy duct shop, and together they are the spine of this whole page.
This guide is written for the person making the call — the owner, the production manager, the foreman of a Melbourne or Victorian sheet-metal shop who is deciding whether to put in a new automatic duct line, add a spiral tubeformer, or replace ageing manual equipment that is throttling throughput. We will walk the local market, the construction pipeline feeding it, the climate and material considerations specific to Victoria, the SBKJ machine line, the see-it-run advantage, the automation-versus-labour maths, ROI, and the standards backdrop — all anchored to the fact that your machinery partner is here in Melbourne, and you can visit today.
2. SBKJ is local — the Box Hill North home-city advantage
Start with the thing no interstate or overseas supplier can match: SBKJ’s factory and showroom is at 5 Twyford Street, Box Hill North VIC 3129. That is in Melbourne’s eastern suburbs, a short run off the Eastern Freeway corridor and within easy reach of the Monash, Eastern and Western Ring Road network. From a duct shop in Dandenong or Bayswater you are roughly half an hour away. From Campbellfield, Thomastown or Sunshine you are inside an hour. From Laverton North or Truganina out west you cross the city but you are still in the same metropolitan area, same day, no airport involved. Your machinery manufacturer is, quite literally, down the road.
Think about what that does to the buying decision. When the supplier is overseas or interstate, every step of the purchase carries distance friction. You cannot easily inspect the machine. Delivery is a freight and clearance exercise measured in weeks. Install depends on a technician flying in on a schedule that suits them. Service and spares mean a phone call into a different time zone and a wait for a part to ship. The machine might be excellent, but the experience of owning it is shaped by how far away the people who built it are. Distance is the hidden cost in a duct-line purchase, and it is the cost SBKJ removes by being in your city.
Because we are in Box Hill North, the relationship is hands-on from the first conversation. You can come and see the machines before you buy. You can bring your foreman back during the build to check progress. On delivery day our own crew rigs the line in. Our own engineers commission it and train your people. And for the working life of the machine, the team that built it is a short drive away. For a Melbourne fabricator, SBKJ is not a remote vendor — it is a local machinery partner you can stand next to.
This home-city position is also why this is the strongest case SBKJ can make to any fabricator anywhere in the country. We can talk to a shop in any state about delivery and support. But for a Melbourne or Victorian fabricator, we are not pitching a remote service promise — we are offering a factory you can walk into this week. That is a genuinely different proposition, and it is the reason a Melbourne duct shop should look at SBKJ first.
3. Where Melbourne duct shops cluster — the precincts we serve
Melbourne’s sheet-metal and HVAC duct fabrication trade is concentrated in a handful of well-defined industrial precincts, and SBKJ serves all of them from Box Hill North. Knowing where the work clusters matters because delivery, install and service logistics are easiest when your supplier already knows the run to your estate.
In the south-east, Dandenong and South Dandenong remain the heartland of Victorian metal fabrication — a deep cluster of sheet-metal shops, duct fabricators and mechanical-services suppliers built up over decades, with good freeway access via the Monash and EastLink. Braeside, a little closer to the bay, adds another pocket of fabrication and trade-supply businesses. These are the shops that have historically supplied a large share of Melbourne’s commercial duct, and they are an easy delivery run for our crew.
In the north, Campbellfield and Thomastown form the second great fabrication belt, stretching along the Hume corridor — heavy with metalwork, manufacturing and trade businesses, and well placed to supply the growth corridors pushing further north. Many of the SME duct shops feeding northern and city-fringe construction sit here.
In the west, Laverton North, Truganina and Sunshine anchor the fastest-growing industrial frontier in the city. The explosion of logistics warehouses, distribution centres and data-centre projects across Melbourne’s west has pulled fabrication and mechanical-services capacity out this way, and round-duct demand for big-volume warehouse ventilation is particularly strong here — which is exactly where an SBTF spiral tubeformer earns its keep.
In the outer east, Bayswater and Kilsyth host a long-standing cluster of light-industrial and fabrication businesses in the foothills, close to SBKJ’s Box Hill North base — among the quickest delivery and service runs we make. Together, these precincts — Dandenong and South Dandenong, Campbellfield, Thomastown, Laverton North, Truganina, Bayswater, Kilsyth, Sunshine, Braeside and Notting Hill — are the map of Melbourne duct fabrication, and they are all inside SBKJ’s local service footprint. Wherever your shop sits on that map, your machinery supplier is in the same metropolitan area.
4. The VIC construction pipeline driving Melbourne duct demand
A duct shop only invests in a new line when it can see the work to fill it. Melbourne and Victoria have one of the strongest forward construction pipelines in the country, and almost every major project on it is a duct-demand generator. Understanding that pipeline is how a fabricator justifies the capacity an automatic line provides.
The headline driver is the Victorian Big Build — the state’s rolling programme of major transport and social infrastructure. The Metro Tunnel has delivered new underground stations through the city core, each a substantial mechanical-services and ventilation job. The West Gate Tunnel adds major road-tunnel ventilation infrastructure across the inner west. The Suburban Rail Loop, now under construction through the eastern and south-eastern suburbs, is a multi-decade programme of new stations and precincts that will feed duct demand for years. Each of these is not one job but a long tail of stations, services buildings, precinct developments and associated commercial construction.
Aviation is a second engine. Melbourne Airport is progressing its third runway and the long-planned T4 and terminal expansion works, alongside the surrounding airport business precinct — large, ventilation-intensive buildings on a continuous build cycle. Fishermans Bend, Australia’s largest urban-renewal precinct, is converting a vast tract of inner-city industrial land into mixed-use development over the coming decades, with commercial, residential and education buildings all requiring HVAC.
Health and biomedical construction is a third. The Victorian Health Building Authority pipeline includes the new Footscray Hospital and a series of major hospital builds and redevelopments across the state, each a heavy mechanical-services job with stringent ventilation requirements. The Footscray and Parkville biomedical precincts add research and clinical buildings, and the Melbourne Arts Precinct transformation adds major civic construction in the city. Layer on the relentless build-out of data centres across the west and north — some of the most cooling- and duct-intensive buildings constructed anywhere — and the logistics and warehouse boom feeding e-commerce, and you have a pipeline that keeps Melbourne duct shops busy across commercial, civic, health, aviation, industrial and residential sectors at once.
For a fabricator, that pipeline is the business case for capacity. Winning a station package, a hospital fit-out, a data-centre ventilation contract or a warehouse programme means committing to volume and to deadlines. A manual or under-capacity shop cannot reliably hit those numbers; an automatic SBKJ duct line can. And because the work is here in Victoria, a Melbourne fabricator with a local machinery partner can scale capacity quickly when a project lands — add a line, take fast local delivery, and be in production before the interstate competitor’s machine has cleared a port.
5. Melbourne climate and material choice for VIC ductwork
Victoria’s cool-temperate, four-season climate shapes what Melbourne duct shops fabricate, and the machinery has to suit the materials that climate calls for. Melbourne swings hard — cold, damp winters that load heating systems, and hot, dry summer spells that push cooling, sometimes in the same week. That wide heating-and-cooling swing means commercial buildings here run substantial HVAC plant and substantial ductwork, both supply and return, across the year. The duct volume per building tends to be high precisely because the climate demands both heating and cooling capacity rather than one dominant mode.
For most Melbourne commercial duct, galvanised steel coil remains the workhorse material, and every SBKJ line is built to run it efficiently — the SBAL-V automatic rectangular line and the SBTF spiral tubeformers are configured for galvanised as standard gauge work. The inland metro climate is moderate from a corrosion standpoint, so galvanised duct serves the bulk of office, retail, warehouse, hospital and apartment work without exotic material.
Where the picture changes is at the bay. Melbourne wraps around Port Phillip, and shops supplying coastal and bayside projects — Fishermans Bend on the water, bayside commercial and residential, marine-adjacent buildings — face a more corrosive salt-laden environment that can call for heavier galvanising, aluminised or, for demanding applications, stainless duct. SBKJ machines accommodate that range: the auto duct lines and spiral formers run aluminised and stainless options as well as galvanised, so a Melbourne fabricator can quote both the standard inland job and the more demanding coastal or specialised job on the same machine family. For health, laboratory, food and cleanroom work — well represented in Melbourne’s biomedical and hospital pipeline — stainless-option capability matters, and it is part of the line specification we walk through at a Box Hill North demo. Material choice is ultimately the fabricator’s and engineer’s call per project; the point is that the machinery does not constrain it.
6. The SBKJ machine line for a Melbourne shop
SBKJ builds a complete duct-fabrication machine portfolio, and a Melbourne shop can configure a line precisely to its job mix. Here is what each machine does in a duct-fab role. All specifications are per the SBKJ Product Catalog 2026 and quoted on request — we never invent numbers, and we will confirm every figure against the catalogue for your quote.
The SBAL-V automatic rectangular duct line is the centrepiece for most commercial shops. It integrates the core rectangular-duct steps — taking coil through cutting, notching, lock-forming and TDF flange forming — so a shop produces flanged rectangular duct in a continuous flow rather than handling each step on separate manual machines. For the bulk of Melbourne’s office, hospital, apartment and commercial supply-and-return duct, this is the machine that sets throughput. The SBAL-III is the heavier-gauge auto duct line for shops working thicker material and heavy-duty rectangular duct.
Around the core line sit the supporting machines. The SBSF-1525 sheet feeder and shear handles flat-stock feeding and shearing, blanking sheet for fittings and custom work. The SB-ZF1500 plasma cutter cuts profiles, transitions and custom geometry from plate and sheet. The SBFB-1500 TDF flange former produces the TDF flange profile that has become the Australian commercial standard for rectangular-duct jointing. The SBPC1500 forms the Pittsburgh lock seam — the staple longitudinal seam for rectangular duct and fittings. The SBLR-600 flexible-duct rollformer handles flexible and round-fitting rollforming for the lighter end of the work.
For round duct, the SBTF-1500, SBTF-1602 and SBTF-2020 spiral tubeformers produce spiral round duct across a range of diameters — the right geometry for warehouse, logistics, data-centre and large-volume ventilation work that is booming across Melbourne’s west and north. A spiral line is often the first or second machine for a shop targeting that warehouse and distribution-centre pipeline.
A typical Melbourne starter configuration is an SBAL-V with an SBPC1500 and an SBFB-1500 for rectangular work, adding an SBSF-1525 and SB-ZF1500 for cut-and-blank flexibility, and an SBTF spiral line once round-duct volume justifies it. A round-duct-led shop might reverse that order. The right mix depends entirely on your job profile — which is exactly what we work out with you at a Box Hill North demo by running your actual duct on the candidate machines.
7. See it run before you buy — the Box Hill North showroom
This is the single strongest reason for a Melbourne fabricator to choose SBKJ, and it is only possible because we are local. At our Box Hill North office and showroom you can watch the machines run before you spend a dollar. Not a video. Not a brochure photograph. The actual machine, running real coil, in your home city.
Here is how a demo works. You book a visit, and you bring two things: your shop drawings, and ideally a sample of the coil you actually run. When you arrive, we load your gauge into the candidate machine and run your real duct profile — rectangular duct off the SBAL-V, spiral off an SBTF line, a TDF flange off the SBFB-1500, a Pittsburgh seam off the SBPC1500. You watch finished, dimensionally correct duct come off the line, made to your job. You can put a tape over it, check the seam, check the flange, and judge the output with your own eyes and your own standards.
That changes the risk profile of the entire purchase. A duct line is a serious capital commitment, and buying one sight-unseen — trusting a spec sheet and a supplier’s video filmed somewhere far away — is a leap of faith. Watching the machine make your duct in front of you removes the guesswork. You see the cycle time, the changeover, the quality and the ergonomics before you commit, and you size the line to what you have actually seen it do, not to a printed claim.
It is also where the conversation gets useful. With the machine running, our engineers and your foreman can talk through your real production problems — the awkward job, the tight gauge, the changeover that costs you time — and work out the right configuration together. For a Melbourne or Victorian shop, that half-day at Box Hill North is the most valuable step in the whole buying process, and it costs you a short drive across town, not an interstate flight and a hotel. No other supplier to the Victorian market can offer a local fabricator that.
8. Automation versus Victorian labour costs
The economic case for an automatic duct line in Melbourne comes down to labour. Skilled sheet-metal tradespeople are valuable, in demand, and not cheap — and in Victoria, like the rest of Australia, the cost of skilled fabrication labour has only climbed. A manual or semi-manual duct shop turns expensive skilled hours into duct one handling step at a time: cut here, notch there, form a seam, fit a flange, each with a person and a machine. The labour content per metre of duct is high, and the throughput is capped by how many hands you can hire and keep.
An automatic line like the SBAL-V attacks that directly. By integrating the cut, notch, lock-form and flange steps into a continuous flow, it converts a sequence of manual handling operations into one machine-paced process tended by fewer operators. The same crew produces far more finished duct, and the skilled tradespeople you do employ shift from repetitive handling onto setup, quality, fit-up and the complex fittings where their skill actually adds value. You are not replacing your trade workforce — you are getting far more output from it, and removing the bottleneck that caps how much work you can take on.
That maths is especially sharp in Melbourne right now because of the pipeline. When there is a strong forward order book — station packages, hospital fit-outs, data-centre contracts, warehouse programmes — the constraint on a duct shop’s growth is rarely the work; it is the capacity to make duct fast enough with the labour available. Automation lifts that ceiling. A shop that can produce more duct per labour hour can quote more aggressively, take on bigger packages, and hit tighter site deadlines without a hiring scramble in a tight labour market. The line pays for itself in the labour it saves and the work it lets you win.
And the automation case is strongest when the machine is local. The labour savings only materialise if the line is actually running — uptime is everything. A locally supplied, locally serviced SBKJ line with Box Hill North spares behind it stays up, which means the automation maths holds in practice, not just on a spreadsheet. An imported machine that sits idle waiting weeks for an overseas part is an automation case that has fallen over. Local supply is what makes the labour saving real.
9. Same-day delivery, install and commissioning across metro Melbourne
Because the machines are built and held in Box Hill North, SBKJ delivers and installs faster within Melbourne than anyone shipping into Victoria from elsewhere. This is the operational heart of the local advantage.
For an in-stock machine — an SBAL-V, SBFB-1500, SBPC1500, SBLR-600 or SBTF line on our floor — we can routinely deliver same-day or next-day to a metro Melbourne address. There is no interstate freight to book, no container to clear through a port, no demurrage, no cross-country transit risk, and no waiting on a shipping schedule. The machine is already in your city; getting it to Dandenong, Campbellfield, Thomastown, Laverton North, Truganina, Bayswater, Kilsyth, Sunshine, Braeside or Notting Hill is a local delivery run with our own rigging crew, not an international logistics project.
Rigging and install are handled by our Melbourne team. We bring the line in, position it on your floor, and set it down level and square. Then our commissioning engineers connect three-phase power and compressed air, run the machine through commissioning, and prove the duct output against AS/NZS 4254 tolerance on your own coil — cut accuracy, lock-seam tightness, TDF flange dimension, and for spiral, seam pitch and roundness. The first duct off the line is saleable duct. For a Dandenong or Campbellfield shop this is a same-week sequence from delivery to first production, because the people doing it are based in Melbourne, not flying in on a distant schedule.
That speed is worth real money on a busy shop. Every week a new line is delayed in transit or waiting on an interstate installer is a week of capacity you have paid for but cannot use, and potentially a site deadline you cannot hit. Local delivery and local install compress that dead time to near zero. When a Big Build package lands and you need capacity now, a local SBKJ line can be delivered, installed, commissioned and producing while a competitor’s imported machine is still on the water.
10. Operator training, service and spares in Victoria
Buying the machine is the start of the relationship, not the end — and this is where being local pays off for the entire working life of the line. SBKJ’s training, service and spares are all Melbourne-based.
Training happens on your machine, on your floor, on your jobs. Our engineers train your operators and foreman on coil loading, profile setup, changeover, daily maintenance, wear-part replacement and safe operation suited to a WorkSafe Victoria duty-of-care environment. Because we are one suburb over in Box Hill North, training is not a one-shot fly-in event. A refresher session, training for a new hire, or a foreman check-in after the first few production weeks is a short drive for us — the kind of ongoing support that is logistically painful when your supplier is interstate or overseas, and easy when they are local.
Service response is the fastest in the country, and it is the core reason to buy local. A duct line that is down is lost throughput and missed deadlines, and on a Big Build programme that is a serious problem. For a Melbourne shop, an SBKJ service engineer is metro-based and can get to site fast. There is no waiting for an interstate technician to be scheduled or an overseas specialist to fly in — the support is in your city.
Spares are the other half of uptime, and we hold wear and consumable spares for the SBAL-V, SBAL-III, SBSF-1525, SB-ZF1500, SBFB-1500, SBPC1500, SBLR-600 and SBTF lines at Box Hill North. When a Melbourne shop needs a part, it is often on the shelf here rather than on a boat, and for many items you can collect it from Box Hill North the same day to keep a line running. That is the difference between a stoppage measured in hours and one measured in the weeks it takes to ship a part across the world. For a Victorian fabricator, local spares and local service is the single biggest practical reason the machine you buy actually keeps making money.
11. VIC standards and compliance — NCC, AS/NZS 4254, AMCA Victoria, WorkSafe Victoria, SMACNA
The duct a Melbourne shop makes has to satisfy a stack of Australian standards and Victorian regulatory expectations, and SBKJ machinery is built to make hitting them routine. A quick map of the backdrop:
The National Construction Code (NCC), the Australian building-code framework that applies in Victoria, governs the buildings your duct goes into and the mechanical-ventilation outcomes they must achieve. AS 1668.2 is the mechanical-ventilation standard VIC mechanical contractors design to — it sets the ventilation rates and air-handling requirements that drive how much duct, and what kind, a project needs. AS/NZS 4254 is the sheet-metal duct construction standard: it defines how rectangular and round duct must be built across the low, medium and high pressure classes, including seam and flange construction. Every SBKJ line is built to produce duct that meets AS/NZS 4254 construction — that is the whole point of the dimensional accuracy, seam integrity and flange quality the machines deliver, and what our commissioning engineers prove on your coil at handover.
AMCA Victoria — the Victorian branch of the Air Conditioning and Mechanical Contractors’ Association — represents the mechanical contractors who are your customers, and AMCA quality expectations flow back to the duct you supply them. SMACNA (the Sheet Metal and Air Conditioning Contractors’ National Association) construction standards are widely referenced in commercial duct specification, and SBKJ machines produce seams and flanges aligned with that construction practice. AIRAH, the Australian Institute of Refrigeration, Air Conditioning and Heating, is headquartered in Melbourne and sets much of the professional and technical backdrop for the local HVAC industry. NECA Victoria covers the electrical-services side that runs alongside mechanical on most projects.
On the machinery and workplace side, WorkSafe Victoria sets the duty-of-care environment your shop operates under. SBKJ supplies machines with the guarding and controls suited to safe operation in a Victorian workplace, and our commissioning engineers walk your team through safe operation at handover. Victoria’s strong trades-training base — Holmesglen, Box Hill Institute and Kangan Institute all run sheet-metal and HVAC-related trades training — feeds the skilled operators your shop relies on, and machinery that is straightforward to set up and run helps newly trained operators get productive quickly. Compliance of the finished duct on any given project rests with the fabricator and the engineer of record; SBKJ’s job is to supply machinery that makes meeting those standards the default outcome rather than a constant battle.
12. ROI for a Melbourne fabricator
The return on a duct line for a Melbourne shop comes from four levers, and being local sharpens every one of them.
The first lever is labour productivity. As covered above, an automatic line like the SBAL-V converts a sequence of manual handling steps into a machine-paced flow, so the same crew makes far more duct. In a tight Victorian labour market where skilled tradespeople are expensive and hard to find, more output per labour hour is the dominant driver of payback. The line lets you grow throughput without a proportional growth in headcount.
The second lever is capacity to win work. Melbourne’s pipeline — Metro Tunnel, West Gate Tunnel, Suburban Rail Loop, Melbourne Airport, Fishermans Bend, the hospital programme, data centres, warehouses — rewards shops that can commit to volume and deadlines. A higher-capacity line lets you quote bigger packages and hit tighter programmes, turning the pipeline into revenue you could not previously chase. The machine does not just save cost; it expands the work you can take.
The third lever is quality and rework. Consistent, machine-made duct to AS/NZS 4254 tolerance means less scrap, less rework, fewer site fit-up problems and fewer rejected loads. On a programme with stiff penalties for delay, reliable quality is money saved that rarely makes it onto the headline ROI calculation but matters enormously in practice.
The fourth lever — the one only a local supplier delivers — is uptime and lead-time certainty. The first three levers only pay off if the line is running and was installed on time. A locally delivered, locally installed, locally serviced SBKJ line with Box Hill North spares behind it minimises the dead time between purchase and production, and minimises downtime over the life of the machine. An imported line that arrives weeks late and then sits idle waiting for an overseas part has an ROI on paper that never materialises on the floor. For a Melbourne fabricator, the local machinery partner is what turns a good ROI projection into a real one — and you can come to Box Hill North and check the machine that underpins it before you commit a dollar.
13. Why SBKJ for a Melbourne or Victorian duct shop
Pulling it together, here is why a Melbourne fabricator should make SBKJ the first call:
- We are local — literally in your city. Our factory and showroom is at 5 Twyford Street, Box Hill North VIC 3129, in Melbourne’s eastern suburbs, within an easy run of every major duct-fab precinct from Dandenong to Laverton North.
- See it run before you buy. Come to Box Hill North, load your own coil, run your own profile, and watch finished duct come off an SBAL-V or SBTF line before you spend a dollar. No video, no brochure — the real machine in your home city.
- Fastest delivery in the country. The machine is already here. Same-day or next-day delivery across metro Melbourne for in-stock lines, with our own rigging crew — no interstate freight, no port clearance wait.
- Local install, commissioning and training. Melbourne-based engineers rig, commission and prove the line on your floor and train your operators on your jobs, often same-week for a metro shop.
- The fastest service and spares in Victoria. A metro-based service team and Box Hill North spares stock for every machine in the range — downtime in hours, not the weeks of an overseas part wait.
- A complete, configurable machine line. SBAL-V, SBAL-III, SBSF-1525, SB-ZF1500, SBFB-1500, SBPC1500, SBLR-600 and SBTF-1500/1602/2020 — rectangular, round, flange, lock and plasma, sized to your real job mix.
- Built for Australian standards. Machinery built to produce duct to AS/NZS 4254 and the AS 1668.2 outcomes VIC mechanical contractors design to, aligned with AMCA Victoria and SMACNA construction practice.
- A partner you can drive to. Not a remote vendor — a Melbourne machinery manufacturer you can visit this week and stand next to for the working life of your line.
For a duct shop in Dandenong, Campbellfield, Thomastown, Laverton North, Truganina, Bayswater, Kilsyth, Sunshine, Braeside or Notting Hill, that combination is not available from any interstate or overseas supplier. It is the home-city advantage, and it is the reason SBKJ should be your first call.
14. Frequently asked questions — Melbourne duct machinery
Can I visit and see a machine actually running?
Yes — that is the whole point of buying local. Book a site visit to our Box Hill North office and showroom, bring your shop drawings and a coil sample, and we will run your actual duct profile on the candidate machine so you watch finished duct come off the line before you buy. Most metro Melbourne shops are 30 to 45 minutes from our door.
How quickly can I get a line within Melbourne?
For in-stock machines, often same-day or next-day delivery to a metro Melbourne address with our own rigging crew, because the machine is already here in Box Hill North. No interstate freight booking, no port clearance, no container wait.
Do you install and train locally?
Yes. Melbourne-based engineers deliver, rig, commission and prove the line against AS/NZS 4254 on your floor, then train your operators on your own jobs — typically same-week for a metro shop, with easy follow-up because we are one suburb over.
What is your service response in Victoria?
The fastest in the country. A metro-based service team plus Box Hill North spares stock for the full machine range means a stoppage is measured in hours, not the weeks it takes to ship an interstate or overseas part.
Which machine should a new Dandenong shop start with?
Usually an SBAL-V automatic rectangular duct line, paired with an SBPC1500 Pittsburgh lock former and an SBFB-1500 TDF flange former, adding an SBTF spiral tubeformer once round-duct demand justifies it. Round-duct-led shops may start with spiral. Come to Box Hill North and we will run your real job mix to size it properly. Specifications per the SBKJ Product Catalog 2026, quoted on request.
Are you at ARBS 2026?
Yes, SBKJ is exhibiting at ARBS 2026 in Sydney in May 2026. But as a Melbourne or Victorian fabricator you do not need to wait for or travel to a Sydney show — book a Box Hill North demo any week and see the machines run in your own city.
Can I pick up parts directly from Box Hill North?
Yes — local pickup of spares, consumables and smaller equipment from Box Hill North is available, so a metro Melbourne shop can collect a wear part the same day to keep a line running. Full duct lines we deliver and rig with our own crew.
Does the machinery suit Victorian standards and workplace requirements?
Yes. The machines are built to produce duct to AS/NZS 4254 and the AS 1668.2 outcomes VIC contractors design to, aligned with AMCA Victoria and SMACNA practice, and supplied with guarding and controls suited to a WorkSafe Victoria duty-of-care environment, with safe-operation training at handover.
15. How to set up an HVAC duct fabrication line in Melbourne
A practical seven-step plan for a Melbourne or Victorian shop standing up or upgrading a duct line with SBKJ:
- Map your job mix and your shop floor. Write down your real Victorian job profile — rectangular versus round, gauges, pressure classes, monthly metres — and measure your Dandenong, Campbellfield or other shop for run length, three-phase power, compressed air and coil access. This is what we size the line against.
- Visit our production operation and see the machines run. Book a demo at 5 Twyford Street, Box Hill North VIC 3129. Bring your drawings and coil sample, and watch your actual duct profile run on the SBAL-V, SBTF, SBFB-1500 or SBPC1500 before you commit — a half-day, not an interstate trip.
- Configure the line and get a catalogue-accurate quote. A common Melbourne starter is an SBAL-V plus SBPC1500 and SBFB-1500, with SBSF-1525 and SB-ZF1500 for cut-and-blank, and an SBTF spiral line for round-duct work or the SBAL-III for heavy gauge. Every spec is taken verbatim from the SBKJ Product Catalog 2026 and quoted on request.
- Take fast local delivery and rigging. For in-stock lines, same-day or next-day delivery across metro Melbourne with our own crew — no interstate freight or port wait. Inspect configured machines at Box Hill North before they leave our floor.
- Commission the line and prove the duct. Our Melbourne engineers connect power and air, run commissioning, and prove output against AS/NZS 4254 on your coil so the first duct off the line is saleable.
- Train your operators on your floor. Operators and foreman learn setup, changeover, maintenance and safe operation under a WorkSafe Victoria environment, with easy local follow-up.
- Go to production with local service and spares behind you. Run your first commercial duct backed by a metro service team and Box Hill North spares, and scale the line with more SBKJ machines from the same local partner as your VIC workload grows.
Start at step two — book the demo — and the rest follows naturally. The whole process is built around the fact that your machinery partner is here in Melbourne.
16. Talk to your local Melbourne duct-machinery team
If you run a sheet-metal or HVAC duct shop anywhere in Melbourne or Victoria and you are weighing up a new or upgraded duct line, the first and easiest step is to come and see the machines run. SBKJ Group is in Box Hill North, in your city. Book a site visit, bring your coil and your drawings, and watch an SBAL-V or SBTF line make your duct before you spend anything. Then take the fast local delivery, the local install and commissioning, the on-floor training, and the fastest service and spares in the country — all from a machinery manufacturer one suburb over rather than one country over.
