Custom Metal Fabrication Built for Mining Uptime
In mining, downtime often starts with small fabrication issues that grow under vibration, impact and extreme wear. Distortion throws out alignment, weld details fatigue, and critical interfaces don’t assemble cleanly during a shutdown. That’s why highly specialised equipment like mining grizzlies and mill liner handlers demands a higher standard of custom metal manufacturing and structural steel fabrication.
If you want a quick sense of what this looks like in the real world, our Projects show the mining and heavy industrial fabrication we’ve delivered for clients across Australia.
Custom metal fabrication for grizzlies: Where impact and abrasion punish every detail
A grizzly does a straightforward job in brutal conditions – separating oversize rock from fines early in the material flow. The structure takes repeated impact loads and constant abrasion along bars, rails, chutes and support members. When grizzly fabrication isn’t right, performance drifts: bars deform, spacing changes, material hangs up, and screening efficiency drops. That’s when operators start intervening, and uptime starts leaking away.
This is where custom metal manufacturing matters. We build grizzly assemblies as wear systems, designed to stay true for longer, remain serviceable, and behave predictably between planned maintenance windows. That level of reliability comes from experience: understanding load paths, anticipating wear zones, and fabricating steel to hold up under relentless vibration and shock.
Custom metal fabrication for mill liner handlers: Geometry, fit-up and repeatability
Mill liner handlers operate in a high-consequence window where time is tight and any hold-up costs real money. At DWW Engineering, we regularly manufacture critical components that need to integrate seamlessly with OEM designs such as a radial drilling arms and other heavy-duty attachments.
For these parts, small fabrication errors can create big problems. Misalignment at mounting interfaces, distortion through structures, or inconsistent hole patterns can cause fit-up issues on site, accelerated wear in service, and rework during shutdown windows. Our focus stays on component accuracy, structural integrity, and repeatable build quality so OEMs and maintenance teams can install with confidence.
Fabrication details and processes that protect uptime
No two sites are truly identical. Ore characteristics, existing transfer geometry, access constraints, shutdown sequencing and maintenance preferences all drive changes. The practical value of custom metal manufacturing is the ability to adapt: Modifying mounting and lifting provisions, adjusting interfaces to suit existing conveyors or chutes, and building in serviceability so wear parts can be changed faster.
Custom metal fabrication for OEMs
OEMs often need two things at once: flexibility for design changes, and consistency for production runs. We support both, which helps reduce variation between units and improve field reliability over time.
That repeatability is where uptime benefits compound: Fewer installation surprises, fewer early-life issues, and more predictable maintenance behaviour across a fleet.
