Steel Grating Standard Specification

Steel grating is commonly made of flat steel panel and supporting bars welded together with setting spacings. It goes through cutting, opening, edging and other processes. The popular vertical bar grating spacing is 30mm, 40mm or 60mm, horizontal bar grating is 50mm or 100mm normally. Details information please refer to the specification List below.

Surface Treatment: hot-dipped galvanized or electro galvanized mild steel.

Features:
The products enjoy the features of high strength, light structure, high bearing, convenience for loading and other properties.

Applications:
Steel grating is widely used in the platform, flooring, corridor, bridge, well covers, stairs, fencing for petroleum, chemical, power plant, waste treatment plant, civil engineering projects and environmental projects.
