Hot dipped galvanized/electro galvanized Steel Grating

 

Steel Grating Mesh 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

 

1.Material: carbon steel

 

 

 

2.Types: We produce three kinds of steel gratings, they are Plain Style Steel Grating, Serrated Style Steel Grating and I Bar Type Steel Grating. They are widely used in steel structure platforms, stair treads, sidewalks, drainages and well covers etc.

 

 

3. The common Type:

Bearing bar centers at 20mm: 

This kind of fine mesh steel gratings have strong load ability and also can prevent the access of sundries of 18mm in diameter. This kind of gratings fit for pedestrian deck, walkway and ditch covers which require high security.

Bearing bar centers at 30mm: 

This kind of steel grating is the most commonly used in projects with American, Australian, Japan standards are available. This kind of gratings are featured well by heavyduty, well resistance of strong impact on surface. Gratings with cross bar centers at 50mm can bear lateral impact well. This kind of steel grating fit for all kind of industrial platforms. 

Bearing bar centers at 40mm: 

light grating and very economical. This kind of gratings fit for fixed platforms, walkway, and stair treads and British, German,French and Japanese standards are available. The products most commonly used for Belt corridor, storage shelf,Attic panel, trestle, guardrail, sunshade gate, etc.

 

 

4.Advantages: They are have many adeantages,such as easy construction,big bearing capacity,good looking and long durability through hot galvanizing for the surface treatment.

 

 

 

5.Usage: They are widely used in municipal engineer walkways,shools,residential quarters,garden facilities,stadium,port,industry,oil and chemistry projects etc .
