hot-dip galvanized steel grating For Drainage Covers

hot-dip galvanized steel grating For Drainage Covers
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.
