Galvanized Compound Steel Bar Grating Floor Composite Metal Steel Grating With Checker Plate Grating
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.
composite lattice steel plate by hot-dip zinc processing, it will be due to thermal stress generated warpage, in particular the use of larger models steel grid plate, school-more difficult, please note that selection.
Applications:
Compound steel grating is widely used in the platform, corridor, bridge, well covers and stairs, fencing for petroleum, chemical, power plant, waste treatment plant, civil engineering projects and environmental projects. Because of its robust design and spanning abilities, this kind of grating is extremely strong and safe for the supportive structures on deckings, mezzanine floors and elevated walkways.
