Mining 
Structural steel fabrication & site install
Remote-site structural fabrication for a Tier 1 mine. Heavy plate, weathering steel, on-site assembly.
ISO 9001SCA CC3
Steel fabrication, precision machining, process systems and site installation for Tier 1 mining, oil & gas, rail and heavy industrial clients. Sydney-based, nationally delivered.
HWM is a fully integrated engineering, fabrication and construction company. We take a project from initial design brief through detailed engineering, fabrication, precision machining, and site installation — without handing off to a third party at any stage.
The result: reduced interface risk, a single point of accountability, and a partner who understands the full scope from day one.
