Steel fabrication experts
At Alted Engineering we deliver structural steel and custom fabrication projects across the Coromandel and Waikato.
From residential homes to light commercial buildings, our work covers frames, beams, staircases, balustrades, gates, fencing, decks, and bespoke detailing — built tough, with a clean finish.
Our Tairua workshop is fully equipped for fabrication, while our team can also transport, erect, and weld on-site. We work closely with builders, architects, and homeowners to ensure every component fits seamlessly and performs as it should.
Whether it’s structural steel supply, coastal fencing, or a one-off custom build, Alted brings precision, strength, and reliability to your project.
Architects
We collaborate with architects to define and deliver steel structures, staircases, balustrades, and other custom architectural elements — bringing design concepts to life with precision fabrication.
Builders
From residential homes to commercial projects, we fabricate and install the steel you need, working seamlessly alongside your building team on-site or from our Tairua workshop.
Councils + Contractors
We partner with councils and roading contractors to deliver robust, fit-for-purpose steel solutions — from coastal fencing and whalers to community facilities and infrastructure projects.
