Advantage of the steel grating:
-light weight-easy to install and clean-nodem
-nice appearance-high strength-ventilation and light can pass through
-material saving-slip-resistant and safe
-heavy loading and durable

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 accident.
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.
The package of galvanized steel grid
galvanized steel grid is normally packed in the way with two pieces of square wood on both upper and bottom sides.there are four or six pieces M10 long bolt penetrating the grids and screwing them together.it is suitable for loading and unloading by forklift.But we also packing our products on costumer’s requirement.
