Description

Mild Steel Heavy Duty Steel Grating 75mm x 6mm 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. Steel Grating Material:Q235 Steel or stainless steel grating.
2. Steel Grating Surface Treatment: Untreated, Painting or Hot Dipped Galvanizing
