Compound steel grating is composed of checkered plate on sealed surface & steel grating with certain spanning capability. Compound steel grating is formed of any type of steel grating and checkered plate in different thicknesses.
Compound Steel Grating. Composite steel grid grating is composed by steel grid grating of certain load-bearing and checkered plates. This kind of bar gratings may deform going through the hot dipped zinc coating process. So heavy type steel bar with big gauge is normally chosen in making composite steel grid gratings. The checkered plates are normally in the thickness of 3 mm, 4 mm, 5 mm or 6 mm.
