GalvanisedSteel
Zinc-coated steel for superior corrosion resistance — sheet, coil, hollow sections, pipe and purlins for Australian conditions.
Galvanised steel is carbon steel protected by a metallic zinc coating that resists corrosion in exposed, coastal and high-humidity environments. We supply the full range of galvanised products — from continuously hot-dip galvanised sheet and coil through to pre-galvanised hollow sections, pipe and cold-formed purlins — with zinc coating mass selected to suit the service environment. All products are sourced to AS 1397 and AS/NZS coating standards with mill test certificates and full traceability.
Product Range
Hot-Dip Galvanised Sheet & Coil
Continuously zinc-coated flat steel with coating mass from Z275 to Z600. Base metal thickness 0.13–3.0mm for roofing, purlins, framing and general fabrication.
Pre-Galvanised Hollow Sections
In-line galvanised RHS, SHS and CHS in a range of sizes and wall thicknesses for framing, posts and architectural applications.
Galvanised Pipe & Tube
Pre-galvanised and hot-dip galvanised pipe for fencing, scaffolding, handrails, services and structural use.
Galvanised Purlins & Sections
Cold-formed C and Z purlins and structural sections in galvanised finish for roofing and walling support.
Hot-Dip Galvanising After Fabrication
Batch hot-dip galvanising of fabricated steelwork to AS/NZS 4680, with coating thickness suited to the corrosivity category.
Common Applications
- Coastal and marine structures
- Fencing, gates and posts
- Roofing, purlins and cladding support
