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.
