Product Description

Heavy Duty Galvanized Steel Welded Serrated Anti-slip Trench Cover Floor Bar Grating

Press-locked steel bar grating manufactured through a precise process of slotting, pressure lock plug insertion, and finishing. At the intersection points of flat steel and horizontal poles, the horizontal pole is pressed into the loading flat steel and securely fixed. In some configurations, flat steel may also serve as horizontal poles.

This versatile grating is widely used for flooring, catwalks, mezzanines/decking, stair treads, fencing, vault bin flooring, ramps, docks/warehouses, trench covers, window and machinery safety guards, wash racks, ventilation screens, storage racks, suspended ceilings, drainage pit covers, and various industrial applications.
