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.
