Steel Grating – Welded Platform, Walkway, and Trench Cover
Steel Grating is used for platforms, walkways, stair treads, trench covers, drainage covers, bridge side paths, and industrial flooring. It is made from bearing flat bars and cross bars by pressure welding or press locking. Common materials include Q235 low carbon steel, galvanized steel, and stainless steel. Alloy steel can be checked by order. Surface can be plain, serrated, or I-bar type (I-bar available by order). Hot dipped galvanized finish is often used for outdoor projects. Panel size, bearing bar size, bar spacing, cross bar spacing, surface type, finish, and edge banding should be confirmed according to span and load requirement.
