Steel grating is an open-structured steel grid formed by the orthogonal arrangement of bearing flat steel and crossbars at a certain spacing, which is fixed by welding or press lock.

Pieces; The crossbars of steel grating are generally made of twisted square steel, but can also be made of round or flat steel. The materials for steel grating are divided into carbon steel and stainless steel.

Grating is primarily used for structural platform panels, manhole covers, stair treads for steel ladders, and ceiling systems in buildings.
