About
Northline Metalworks is a Melbourne metal fabrication workshop producing structural steel, architectural metalwork, balustrades, gates and fencing for residential builders, commercial contractors, architects and property owners.
Northline Metalworks started in 2009 in a two-bay shed in Campbellfield, doing repair welding and small fabrication runs for builders across Melbourne's north. The work that kept coming back was the work nobody else wanted to detail properly — retrofit steel into existing buildings, balustrades that had to satisfy a building surveyor, gates that had to hang true on a sloping driveway.
That is still the centre of the business. We have grown to fourteen people and a purpose-fitted workshop, but the thing that gets us repeat work from builders and architects has not changed: we resolve the detail before we cut, and we tell you early when something in the documentation will not work.
Today the workshop runs structural steel for commercial builders alongside architectural metalwork for architects and one-off residential pieces for homeowners. Those are very different clients with very different expectations, and we have deliberately kept the capability to do all three rather than specialising into a single lane.
We are not the cheapest fabricator in Melbourne and we do not try to be. What we offer is steel that fits, paperwork that satisfies the certifier, and a program you can build around.

How we operate
Detailing issued for approval on every structural and architectural job, so clashes are found on paper.
Cutting, fabrication, finishing and load-out happen under one roof in Campbellfield.
Certificate of currency issued with every commercial quote, alongside our WorkSafe cover.
Most residential and light commercial enquiries are priced within three business days of a site measure.
Two installation crews and a 4.5 tonne crane truck, so delivery and install stay on our program.
Structural welding carried out to documented procedures in line with AS/NZS 1554.1.
Working with us
Our detailer models every structural and architectural job before a single section is cut. Shop drawings are issued for your approval, which means clashes with services, framing and cladding get resolved on paper rather than on site.
The person who prices your job manages it. You are not passed between an estimator, a workshop manager and an installer, and you are not chasing a subcontractor we have never worked with.
Slabs move, frames rack and heritage openings are rarely square. We check-measure on site before fabrication and detail in the tolerance and adjustment needed to make the steel fit the building you actually have.
Hot-dip galvanising, powder coat colour, primer system and touch-up procedure are written into the quote. You know what turns up, and so does the painter following behind us.
Deliveries are staged to match the trade sequence rather than dumped in one load. On multi-stage commercial work we hold finished items in the workshop until the site is ready for them.
Welder qualifications, material test certificates and inspection records are supplied as part of the job on commercial work, not produced weeks later when the building surveyor asks.
How we work
01
Send drawings, sketches or photographs through the quote form. We confirm what is included, flag anything that looks unresolved, and tell you what else we need.
02
For residential and retrofit work we measure on site. For new commercial builds we work from the architectural and structural documentation and raise RFIs where the detail is unclear.
03
You receive a written quote with inclusions, exclusions, finish specification, lead time and installation requirements. Nothing is priced as a provisional sum unless we say so.
04
We issue shop drawings for approval. Fabrication does not start until they are signed off, which protects both of us from expensive rework.
05
Cutting, forming, welding and assembly happen in the Campbellfield workshop. Galvanising and powder coating are booked in as part of the program, not as an afterthought.
06
Our crews deliver and install, make good, and hand over the documentation package. Any defect items are listed and closed out before we invoice the final claim.
Compliance and insurance
Certificates of currency, welder qualification records and material test certificates are issued on request. If your project requires an inspection and test plan, tell us at tender stage so it is priced in.
What clients say
The trial assembly in their workshop is what sold me. They found two cleat positions that would have meant drilling on site at 2am, and fixed them before the frame went to galvanising. We despatched every morning of that install.

See the project in BrunswickOur stair was already built and it was not perfectly true. Northline templated the whole thing rather than working off the drawings, and absorbed the variation at the landings. Standing at the bottom you would never know.

See the project in KewI have specified perforated screening on a lot of projects and the panel joints usually give it away. They nested the pattern across the whole elevation and cut the panels out of it. That is not the standard approach and it is the reason it works.
