    The steel grating is made of flat steel which is cross-aligned according to a certain spacing and cross bar (twisted square steel, square steel, round steel, flat steel, etc.) and welded into a steel product with a square lattice in the middle.

Anti-soil: no rain, ice and dust


   Lightweight structure: less material, light structure and easy lifting.


   Reduce wind resistance: due to good ventilation, small wind resistance and wind damage.


   Acid-base corrosion ability: In the range of PH 6 to PH 12.5, a stable protective film is formed on the surface of the zinc layer, and the corrosion resistance is good.


   This product is mainly used in steel structure platform, sewage treatment system, drain cover, stair tread
