Building Material Heavy Dut Serrated Steel Grating
Press-locked steel bar grating made by fixed size flat steel through slotted, pressure lock plug, finish, etc process. At the intersection point of flat steel and horizontal pole, press horizontal pole into loading flat steel, then fixed it. Sometimes the horizontal pole also used flat steel.
The grating is widely used for floor, catwalk, Mezzanines/decking, stair tread, fencing; vault bin floor floor, ramp, dock/warehouse, all kinds of trench cover, window and machinery safe guards, wash rack, ventilation screen, storage rack, suspended ceiling, drainage pit cover and etc.
