Welded Bar Grating is made of flat steel and bars by welding with certain distances. The bearing bars are automatically resistance welded at the contact point with the cross bars and, under a combination of high heat and pressure, are fused together to form a permanent joint. The cross bars provide a high degree of rigidity, yet retain a smooth flat surface for free and easy walking.

It goes through cutting, opening, edging and other processes. The products enjoy the features of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the product excellent anti-corrosion resistance.

The type of grating is indicated by a letter as follows

 W  welded

P  press locked

BEARING BAR SPACING

Bearing bar spacing is designated by mm

For welded or press-locked grating, it’s the distance center to center of bars

CROSS BAR SPACING

For welded or press-locked grating, it’s the distance center to center of cross bars
