Series 30 Grating

Series 30 Grating

Weldlok Series 30 grating is recommended for applications requiring high load-carrying capacity. Serrated load bars should be considered where increased walkway safety is required, and cross bars at 50mm centres for high impact loads.

Series 30 Features

– 30mm load bar centres
– Cross rods at 100mm (A) or 50mm (B) for reliable stability
– 3mm or 5mm thick load bars
– Standard or serrated finish
