Instead of welding the joints applied for welded bar grating, however, tremendous hydraulic pressure is used to bond the two close-tolerance slotted bars together in processing of Pressure Locked Gratings.
Rectangular bar grating in either the swage-locked or press-locked styles offers good lateral stiffness. The rectangular bar is also available in a serrated surface for additional safety.
Manufacturing Process: slot (hole), plug the pressure lock, welding, finishing and other processes.
