Weld repair and remediation

Welding errors are surprisingly common in items manufactured overseas. That’s why we specialise in quickly and reliably fixing fabrication issues - such as misaligned holes or welds that don’t meet Australian structural standards. We can deliver where others cannot.

Metal straightening

Everyday wear and tear can take its toll on industrial products such as road plates, pit covers and beams. When these items become damaged and bent, our specialist steel straightening service can return them to usable condition with minimal cost.

Fast and reliable

All repairs can be carried out quickly and safely in our Sydney factory, subject to ISO 19001 quality controls. Once repaired and ready, jobs can be conveniently delivered to your site in NSW or shipped interstate.
