1.) Processing technic:
Steel grating is made by bearing bar and cross bar according to the flat-steel weft arrangement, in high-pressure spacing on resistance welder welded by cutting, incision, opening, overlock process such as processing and into customer requirements finished products.
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.
Widely used in petroleum chemical industry, power plant, water and sewage treatment plants, municipal engineering, environmental sanitation engineering fields of the platform, footpath, zhanqiao pier, ditch lid, manhole cover, ladders, fences, guardrail etc.
Carbon steel, Stainless steel ,and so on .
Hot-dipped-galvanized ,electro galvanized or PVC coated ....
