How is Weldlok® Grating made?
Weldlok® mild steel grating is constructed using an electro- forgewelding process that applies pressure and heat to fuse square, twisted cross bars into load-bearing bars of various thicknesses and depths. The result is a product with a one-piece construction that complies with the requirements of Australian Standard AS1657-1992.

Weldlok® Aluminium Grating is pressure-locked, with crossbars permanently attached to load bars through a swaging process. Grating is available with a range of load bar sizes and spacing and is also available with serrated surfaces for slip resistance.

Weldlok® grating is being used in many environments across Australia
Weldlok® grating is used extensively in many different resource applications throughout Australia including mines, industrial, chemical and sewerage plants, marine environments and superstructures, drilling rigs, architectural projects and tourist sites.
