Heavy-Duty Steel Grating with High Strength and High Bearing Capacity

 

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.

Packaging:

  • Strap packing: Generally used for neat press locked steel grating.
  • Pallet packing: Generally for the press-locked steel grating which need to export and load in container.
  • Screw rod fixation: Use four screw rods through the mesh and fixed with screws.

The standard of heavy duty steel grating: DIN: 1072

Production Process: Heavy-duty steel grating uses automatic welding technology, combined with high temperature and high pressure, a permanent connection is formed between the bearing bar and the cross bar.
