Metal Fabrication
Our fabrication workshop produces custom steel components using 5-tonne overhead cranes and advanced pressing equipment. Capable of handling 60mm thick plate and complex stainless steel formations, we deliver structural beams, pressure vessels, and industrial equipment. With CNC precision and manual expertise, we create railway components, heat exchangers, and custom machinery to Australian Standards.
Welding Services
Certified welders perform SMAW, MIG, TIG, and Arc welding to client specifications. Our in-house supervisor ensures compliance with Australian Standards, while NATA-approved testing verifies weld integrity. Specialising in stainless steel and titanium, we deliver high-quality welds for critical industrial applications with full documentation.
Machine Shop
Equipped with HAAS and AJAX CNC lathes plus Correa milling machines, we handle components up to 6 meters long. Our machining services include bearing overhauls, shaft repairs, and precision thread cutting. The 5,000kg capacity gantry mill supports heavy industrial component refurbishment to exacting tolerances.
Equipment Refurbishment
We restore industrial equipment to operational excellence through systematic strip-and-assess processes. Providing detailed reports with repair recommendations and life-extension strategies, our team completes refurbishments to original specifications. This includes precision machining of replacement parts and comprehensive quality verification.
Surface Treatment
Our 6x6x8m blasting booth handles classes 1-5 grit blasting requirements. We apply three-coat industrial finishes, high-temperature coatings, and acid-resistant epoxies. The abrasive blasting service prepares surfaces for optimal coating adhesion, ensuring long-term protection in harsh industrial environments.
