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. Ductile iron Grating 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. Ductile iron Grating superiority: 1----Anti-theft 2----Load-bearing great 3----Corrosion resistant 4----Opens conveniently 5----Superior safety performance Product Description: Drainage ductile iron grating Materials: ductile iron (GGG50), grey iron (GG20) Standard: EN124,BSEN124, UNIEN124 Load weight: B125 C250 D400 E600 Specs: according to all client's drawings Packing: ply wooden pallet / case with plastic layer Paint: anti-rust bituminous painting It is widely used in the urban drainage system and road facilities.
