Heavy steel grating galvanized cover plate industrial steel grating

Introduction of hot dip galvanized steel grating

1>material:carbon steel or stainless steel

2>cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.

3>Steel grating is made by the world first-class equipment,which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high tension resistance weldingring which is controlled by computer.so we can produce high quality gratings with firm welding,smooth surface and high strength.

4>Surface process of steel grating:Types:hot-dipped galvanized,electro-galvanized ,spraying brushing. 95% people choose hot-galvanized because its anti-acid and alkali corrosion capacity range is from PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.

5>Attractive appearance:Simple outline.silver colour and modern.

6>Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron.

7>Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free.

8>Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft,safety and convenient opening.

Processes:
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.

Surface treatment:
Hot-dipped-galvanized ,electro galvanized or PVC coated

Size:
Standard size or OEM(Making as the customers' request).

Features
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.

Useage:

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.
