Engineering design
Alted Engineering specialise in mechanical and structural design for residential, commercial, and industrial projects. And everything in between.
Our process begins with concept and preliminary drawings, progressing through detailed modelling and workshop documentation using SOLIDWORKS to ensure accuracy from design to build.
With over 20 years of design experience, our projects span a wide range of industries — from hydraulic stair systems and roading infrastructure components to custom trailers, vehicle modifications, and bespoke architectural steelwork. Whether adapting complex equipment or developing one-off solutions, every design is engineered for performance, safety, and precision.
CAD design
3D visualisation of construction, enabling development, modification and optimisation of the design process.
Workshop drawings
Delivering fabrication drawings, with full detailed plans that show the design intent of your project.
Solution focussed
Defining the problem allows our team to design and deliver a solution that exceeds project criteria.
Bennet Gage-Brown is a highly accomplished engineer who cut his teeth in the transport industry with Australia / New Zealand organisation TRT, an industry leader in heavy transport solutions. Achieving patent designs and defence industry awards while employed by TRT, Bennet has extensive background in heavy transport engineering.
At the forefront of designing cutting-edge equipment with a focus on efficiency, durability, and safety, Bennet's invaluable experience in conceptualising, prototyping, and refining heavy transport machinery has earned him widespread recognition within the transport community.

Mountain bike design
"I enjoy riding and racing mechanical things and understand how they work. And I feel it goes hand in hand with what I look to do in my pastime, it’s like a hobby. Making cool shit. And when you ride bikes and are an engineer, what better project than to design and build your own bike frames."
Bennet Gage-Brown
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.
