Product superiority: 1----Anti-theft 2----Load-bearing great 3----Corrosion resistant Use: Drainage ductile iron grating are mainly used for drainage of municipal roads and general roads, factory drainage, basement drainage, general building drainage facilities and inspection well facilities. Advantage: The tensile strength and pressure resistance of the ductile iron grating are good. Compared with the resin composite material and the cement material, the elongation rate is much improved, and it has good pressure resistance and is not easily damaged.
