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.

 

Notes: common welding standard: single-side full welding every 6 bearing bars. 

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 heavy-duty, 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.

 

Notes: common welding standard: single-side full welding every 5 bearing bars. 

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. 

 

Notes: common welding standard: single-side full welding every 4 bearing bars. 

Bearing bar centers at 60mm: 

This kind of steel gratings are especially used for mining industries. It can solve the problem that mineral splashing down and stacks on the walkway. This product usually used for mineral miningand processing and it is the best choice for workshop, meeting room and suspended ceiling of stadium in terms of it's light weight.

  

 

Notes: common welding standard: single-side full welding every 3 bearing bars.

 

We have many kinds of grating ; we can produce and design gratings according to customer different environment , bearing capacity, span, shape, colour and cost .

 High intensile strength : firmmesh pressing welding structure make it high load bearing;Light structure : easy to liftBeautiful shape ,durable : hot galvanization treatment make it good corrosion resistance ,

smooth surfaceVentilation,lighting, cooling, explosion-proof, non-slip performance;

Standard type: 1m×6m(special sizes are available)Material:Carbon SteelSurface Treatment: Galvanized,Hot-dipped Galvanized or black.Appearance of Surface:Plain or Serrated.
