The steel grating adopts the world-class equipment from the Italian company ORSOGRIL. The flat steel and the twisted square steel are distributed at certain intervals. The computer-controlled high-voltage resistance welding presses the twisted square steel into the flat steel to obtain a firm welding joint. The board surface is flat and contains steel grating with extremely high strength.
