Raw Material:
Grid load flat steel bar: High-quality low carbon steel, galvanized steel, stainless steel, alloy steel.
Horizontal pole: Q235A or 304 stainless round steel, twisted square steel, square steel and hexagonal steel.
Classification: Welded steel grating, standard pressure lock grating, dense grating, ditch cover and ladders
Features: Strong steel structure made it have a high carrying capacity; With good corrosion resistance through surface by hot-dip galvanized; light structure easy to lifting; flat serrated have the character of safety and anti-slip; ventilation, lighting, heat, explosion-proof.
Finish treatment: Hot dipped galvanized, cold dipped galvanized, spray painting, dip anti-rust oil, can prevent oxidation.
Surface type: Flat type, serrated type, I shape type (According to requirement made different protective treatment).
Flat type: The most widely steel grating.
Serrated type: With better non-slip.
I type: On the surface, path and items not in the same flat. With the character of light weight, economic and practical.
