Round Bar Twisted Steel Heavy Duty Steel Grating For Bridge, Store Shelves for Large Carg
Description:
Heavy-duty steel grating can be made by welding and press-locked. It is higher and thicker than the ordinary steel grating. With the features of high strength, high bearing capacity and non-slip, heavy-duty steel grating is widely used as the floors, lanes and rack accessories in the highway, bridge, store shelves for large cargo, parking lot, industrial plant that often use forklift and the traffic junctions, roads or trails that large trucks often come and go.
Features of heavy-duty steel grating
1. High strength and resistance to stress.
2. High bearing capacity it can carry the things of 3 to 60 tons.
3. Non-slip, anti-corrosion.
4. Durable and safe.
5. Easy to install and disassemble extend the lifespan.
Materials & Finishes:
Heavy duty gratings are manufactured in carbon steel and 300 series stainless steels. Carbon steel products are available bare (no finish), painted with manufacturers standard paint, or hot dip galvanized. Stainless steel products are available mill finish, commercially cleaned or electro-polished.

Surface process of grating:
-Hot-dipped Galvanizing
-Normally, hot-dipped galvanizing will be carried out after end welding process.
-When the thickness of bearing bars is not less than 5mm, the weight of average Zinc Layer will not be less than 610g/m2.
-When the thickness of bearing bars is less than 5mm, the weight of average Zinc Layer will not be less than 460g/m2.
-The quality and requirements after hot-dipped galvanizing are according to the standards of GB/T13912.
