Engineering design
Led by a certified SOLIDWORKS engineer with 20+ years of experience, we bring transport-industry precision to every project. From custom trailers and heavy-duty builds to bespoke architectural steelwork, our design-first approach ensures every detail is fit for purpose and built to last.
Steel fabrication
We complete a wide variety of structural steel and custom fabrication projects each year in our Tairua workshop and on-site. Our work includes staircases, balustrades, gates, fencing, decks, and architectural detailing — alongside large-scale structural steel for residential and commercial builds.
Installation
Our team manages delivery and installation end-to-end. We can be on-site installing structural steel, welding balustrades, fitting staircases, or setting coastal fencing — working seamlessly alongside your builder or project team.

Licenced SOLIDWORKS practitioner
At Alted, design comes first. With over 20 years’ experience in CAD and CAE software, owner and engineer Bennet Gage-Brown leads our projects with SOLIDWORKS — the industry standard for precision engineering design.
From custom trailers to structural steel and architectural detailing, in-house design means every project is tailored, accurate, and ready to perform. By modelling in SOLIDWORKS before fabrication, we eliminate guesswork, streamline production, and deliver better results for our clients.
