Earthquake Resistant 30*5 32*5 32*3 Galvanized Steel Grating Supplier
Earthquake Resistant 30*5 32*5 32*3 Galvanized Steel Grating Supplier
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.
Steel grating is an essential structural component of many builds, particularly in commercial and industrial spaces. Steel Grating is specifically designed for high impact, high load applications, such as in walkways, stairs, platforms, and mezzanines. Steel grating is safer, will last longer, and will look better than any other underfoot options for industrial and commercial spaces.
