Easy installation and disassembly industrial used non slip metal steel stairs grate steps
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. So we can produce high quality gratings with firm welding, smooth surface and high strength.
1. Steel Grating Material:Q235 Steel or stainless steel grating.
