Welded Bar Grating Heavy Duty Steel Grating Banding Untreated Surface

Welded Heavy Duty Steel Grating Banding Hot Dipped Galvanized

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. Materials & Finishes

Heavy duty gratings are manufactured in carbon steel and 300 series stainless steels. Carbon steel products are available bare (no finish), painted with manufacturers standard paint, or hot dip galvanized. Stainless steel products are available mill finish, commercially cleaned or electro-polished.

2. Steel Grating Surface Treatment: Untreated, Painting or Hot Dipped Galvanizing
