Steel grating is made by the world first-class equipment,which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high tension resistance welding ring which is controlled by computer. The material of steel grating is mainly Carbon steel Q235, and the surface is hot dip galvanized, which can prevent the grating from oxidation, also we can make it in stainless steel 304/316. The steel bar grating has the advantage of ventilation, good lighting, anti-slip, explosion-proof, etc. we can can produce high quality gratings with firm welding,smooth surface and high strength. 255/30/100G is one of the most popular size.
