Compound Steel Grating
Composite steel grid grating is composed of steel grid grating with
certain load-bearing capacity and checkered plates. This type of
bar grating may deform during the hot-dipped zinc coating process,
so heavy-type steel bars with large gauges are typically selected
for composite steel grid gratings.
The checkered plates are normally available in thicknesses of 3mm,
4mm, 5mm, or 6mm. Due to thermal stress generated during hot-dip
zinc processing, the composite lattice steel plate may experience
warpage, particularly when using larger models of steel grid
plates.
Applications
Compound steel grating is widely used in platforms, corridors,
bridges, well covers, stairs, and fencing for petroleum, chemical,
power plants, waste treatment plants, civil engineering projects,
and environmental projects. Its robust design and spanning
capabilities make it extremely strong and safe for supportive
structures on deckings, mezzanine floors, and elevated walkways.
