Structural Steel Fabrication
Kelly Steel are structural steel fabricators in Melbourne, operating from our Dandenong South workshop. We deliver structural fabrication for commercial, industrial and infrastructure builds across Greater Melbourne, from detailing and procurement through to trial fits, coatings and handover packs, keeping programs tight and sites ready for erection.
As experienced structural steel contractors in Melbourne, we coordinate directly with builders, engineers and certifiers, run lift studies where required and integrate with your erection sequence to minimise delays on site.
What is Structural Steel Fabrication?
Structural steel fabrication is the end-to-end process of turning engineered drawings into certified steel components that bolt or weld together on site. It covers everything from interpreting engineer-approved documentation through to cutting, drilling, welding and finishing steel members to precise tolerances.
In Melbourne, and especially across the Dandenong manufacturing corridor, this work underpins some of the region’s most demanding commercial, industrial and infrastructure projects. At Kelly Steel, our fabrication process typically covers:
- Detailing & procurement
- Cutting & drilling
- Fit-up & welding
- Trial assembly & QA
- Surface treatment
- Packing, delivery & handover
Converting design models and shop drawings into cut lists; sourcing compliant plates, beams and sections.
CNC saws/drills, plasma profiling and coping for accurate fit-up.
Coded welders working to AS/NZS 1554 with WPS/PQR, NDT where specified.
Checking squareness, camber and hole alignment; producing ITPs, weld maps and material certs.
Galvanising or paint systems to spec; protection of finished surfaces.
Sequenced loads, coatings reports, and as-built mark-ups ready for erection.
In practice, fabrication delivers the steel beams, columns, trusses, stairs, platforms, and balustrades your builder installs, keeping programs tight, minimising crane time, and reducing re-work. For Greater Melbourne projects, a Dandenong workshop shortens lead times and supports night or weekend deliveries when city access windows apply.
Who does it?
Structural Steel Fabrication Work is carried out by trade-qualified teams with project management, rigging and welding services, supported by QA and compliance to AS/NZS 5131 and AS 4100. When fabrication and installation sit under one program, transport, cranage and site sequencing are simpler, ideal for commercial, industrial and infrastructure jobs.
Workshop capability (Dandenong)
Our south-east facility handles cutting, drilling, welding, trial assembly and coatings with QA at every stage. If you’re comparing options for steel fabrication in Dandenong, we can fabricate, deliver and erect under a single program with clear milestones and daily updates.
What we build
- Primary and secondary members, trusses, portals and bracing
- Stairs, balustrades, platforms, ladders and access steel
- Plant plinths, pipe bridges, craneway steel and heavy plate items
- Hold-down bolts, plates and custom fixtures to engineer spec
Our team of structural steel fabricators prepares clean, accurate assemblies that go together quickly on site. We also undertake structural fabrication for bespoke components and architectural details, and provide industrial fabrication for process and plant steel where higher duty or specialist procedures are required.
QA, standards and documentation
Work is delivered to AS/NZS 5131 and AS 4100 with qualified welders to AS/NZS 1554. Each package includes ITPs, WPS/PQR, material certs, weld maps, torque records and as-built mark-ups. For shutdowns or fast-track work, our crew is one of the region’s dependable industrial steel fabricators, supported by in-house industrial fabrication services (machining, blasting, galvanising and paint systems to spec).
Delivery, coatings and installation
We sequence loads for cranage, protect finished surfaces, and coordinate site access with the superintendent so the frame stands without delays. If required, our installation teams can erect the package, align members, complete on-site welding and provide survey set-out to close out.
