Delivered packages include 1,251 tonnes of structural steel and platework for Rio Tinto’s Yandi Sustaining Project, 917 tonnes for the Tianqi lithium hydroxide plant, about 500 tonnes of deck steel for the Matagarup pedestrian bridge and 883 tonnes for the PTA Railcar Facility. Laydown and pre-assembly space allows staged delivery and trial fit-up before steel leaves the yard.

Fabrication is certified to AS/NZS 5131 Construction Category CC3 and welding to AS/NZS ISO 3834 Part 2, both audited by Weld Australia, within an ISO 9001:2015 management system certified since 1996. Welding coordination is by AS 1796 Certificate 10 qualified staff; welding processes covered include MMAW, SAW, GMAW, FCAW and TIG to AS/NZS 1554 Parts 1, 4 and 5. Each project carries an inspection and test plan and full material and weld traceability.
