Galvanized steel grating:
The advantage of hot-dip galvanizing is its strong anti-corrosion ability, and good adhesion and hardness of the galvanized layer.
Serrated steel grating:
The model is the same as that of ordinary flat steel. The difference is that there are uneven teeth marks on one side of the flat steel,
and the main function is to prevent slippag.
Stainless steel grating:
Light weight, high strength, large carrying capacity, material saving and economical, ventilation and light transmission, modern style, beautiful appearance, non-slip safety.

Intensity, light structure: strong grid bonding structure makes it with high load, the structure characteristics, facilitate hoisting light; Beautiful appearance, durable: hot-dip galvanized surface treatment make it fairly good corrosion resistance, the surface luster beautiful; Ventilation, lighting, heat dissipation, explosion-proof, prevent slippery properties is good; Deposition prevention dirt.
Plain steel bar grating usages:
Steel Grating is widely used in the platform, corridor, bridge, well covers, stairs, fencing for petroleum, chemical, power plant, waste treatment plant, civil engineering projects and environmental projects.
