Series 1 PB Grating stands for 30mm Load Bar Pitch and is the most commonly specificed and used throughout all industries. Series 1 grating has the strongest resistance to loading impact and is used widely in Power Plants, Refineries, Petrochemical Plants, trafficable drain grates and offshore oil |& gas platforms (in serrated form).
The cross rods are forge welded perpendicularly with equal spacing to the load bearing bras. Twisted square bars (6mm x 6mm) are used for cross rods to maintain the structural precision and perform a non slip function. The cross rod pitch (CP) is 100mm.
