Steel Grating is made by welding with flat steel and bars with certain distances. It goes through
cutting, opening, edging and other processes. The products enjoy the feature of high strength, light
structure, high bearing, convenience for loading and other propertier.
The hot dipped zinc coating gives the product excellent anti-corrosion.
flat bar: plain type, plain I type, serrated type, serrated I type;
cross bar: round type and square twisted type.
electric galvanized, hot dipped galvanized.
They are have many advantages,such as easy construction, big bearing capacity, good looking and long
durability through hot galvanizing for the surface treatment, transmission and aeration, anti-skid and
secure, wears well, non-sagging, non-dirt, and easy to install.
Widely used in the petrochemical industry, power plants, waterworks, sewage treatment plants, municipal
works, sanitation projects in areas such as platforms, corridors, bridge, ditch cover, covers, ladders, fences, rails, and so on.
