Compound steel grating plate for Hot dipped galvanized steel grating for construction:

1.The compound steel grating plate consists of steel grating plate with certain loading ability and surface seal retreader.
2.After hot dip zinc treatment, the compound steel grating plate will warp and distort because of the heat, espacially the great model steel grating plate, difficult to smooth; please note the shaping.

3.The compound steel grating plate commonly takes series 3 steel grating plate as basic plate, also can use series 1 or series 2 steel grating plate. Retreader usually uses 3mm plate, also can uses 4mm, 5mm, 6mm plate.
