Metal Building Materials Galvanized Steel Bar Grating Walkway Price For Construction

Steel grating Xingbei is racking related product. So it is widely used as flooring on mezzanine and steel platform, and as shelving on racking. For its perforated surface, it can meet fire-resistant requirement in many countries. The flat steel and the twisted square steel are distributed at certain intervals. The computer-controlled high-voltage resistance welding presses the twisted square steel into the flat steel to obtain a firm welding joint. The board surface is flat and contains steel grating with extremely high strength.

Steel gratings are widely used in platforms, walkways, trench covers, manhole covers, stair steps, stair platforms, and fences in the fields of petrochemical, electric power, tap water, sewage treatment, port wharf, building decoration, shipbuilding, municipal engineering, environmental sanitation engineering, etc.

PRODUCT FEATURES

Steel grating is made by welding with flat steel and bars with certain distances.other pIt goes through cutting, opening, edging and other processes. The products enjoy the features of high strength, light structure, high bearing, convenience for loading and roperties.The hot dipped galvanized coating gives the product excellent anti-corrosion resistance.
