Structural steel
Strong, structural steel for award-winning builds across the Coromandel, Waikato.
We design, fabricate and install structural steel for residential builds across the Coromandel and Waikato. Every beam, brace and connection is modelled in SOLIDWORKS before it's cut, fabricated in our Tairua workshop, and installed on site by our own crew.
From coastal show homes in the Whitianga Waterways to large architectural builds in Pauanui and Morrinsville, we carry the whole structural steel scope. One crew from drawing to sign-off, so nothing gets lost between the fabricator and the installer.
We've supplied steel for a Master Builders House of the Year winner, opened up existing homes where steel replaces a load-bearing wall, and worked to tight tolerances on hillside sites with difficult access.
Trusted by leading local builders
We’re proud to work alongside some of the Coromandel and Waikato’s most respected builders and architects.
These collaborations showcase the best of local craft and engineering expertise. Recent highlights include:
PJ Builders – structural steel supply and installation for their House of the Year gold-award winning build in Whitianga.
Landmark Homes – precision-installed floating staircase and feature steelwork for their Whitianga Waterways show home.
Percival Construction – full structural steel design, fabrication, and installation for a Whitianga build.
Ohlson & Whitelaw, Urban Homes, Jennian Homes, McCaw Builders, JP Builders, and MDA | Matt Deeb Architecture to name drop just a few!
Every project reinforces why builders choose Alted. Clear communication, dependable timelines, and steel that fits perfectly first time.
Engineering precision meets practical know-how
Our structural steel services include:
Design, detailing, and modelling in SOLIDWORKS
Fabrication of beams, portals, and bracing systems
Hot-dip galvanising and powder-coating for coastal durability
Transport, on-site welding, and full installation
We work closely with architects, engineers, and site teams to ensure seamless delivery because strong builds start with stronger partnerships.
Based in Tairua and working across the Coromandel and Waikato, we understand the demands of coastal environments.
Every project is finished to withstand the elements while maintaining a clean, architectural finish — steel that’s engineered to endure and built to impress.
