Fabricating in Melbourne since 2009
We detail, fabricate, finish and install from a single workshop in Campbellfield — so the steel that arrives on site matches the drawings that were approved.
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.

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.
Who we work for

Commercial
We work as a subcontractor to builders and head contractors on fitouts, warehouses, schools, plant rooms and multi-residential projects, and we understand what that requires administratively as well as technically.

Residential
For renovations, new homes and one-off custom pieces we keep the process plain. You get a measured quote, a clear lead time, and a crew that turns up when we said we would.
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.
Priya Raman
Director, Raman Constructions
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.
