Description of steel grating:
steel grating, also called smooth surface grating, is a type of
grating made of plain steel bars. The smooth surface contrast with
serrated steel grating, which has a serrated surface. plain steel
grating is the most widely used grating type, which is used in
almost all of the applications.
Plain steel grating can be made of carbon steel bar, aluminum steel
bars and stainless steel bars. Cross bars of plain steel grating
can be crimped bars, which are known as riveted steel gratings,
flat square bars which are the press-locked gratings.
The round bars is welded to the bearing bar is welded steel grating
and the bars are placed into the pre-holes on the bearing bars to
form the swage-locked grating.
Steel Grating Features:
Acid-alkali and corrosion resistance; anti-rust; insulation;
weatherability; excellent anti-pressure capability.
It adopts macromolecule complex material and reinforcing steel bar
moulded by high temperature and press at one time.
this kind of material has no recycle worth so it was
burglarproof.At the same time it has locked construction design,it
can make goods in the well avoid stolen.Avoid City Black Hole
Lower price than stipulated standard cast iron ones.
5.Save mine resource
It is made by regenerated resin or regenerated plastic raw
material, which save application of cast iron.
