2. Standards of steel grating



3.We recommend that you choose nominal width as your choice for the convenient processing and attractive appearance of steel grating panels. It’s better to keep the the length in accordance with the width.

calculation formula of nominal width:

nominal width=bearing bar centers×numbers of centers+thickness of bearing centers


 5.Heavy duty steel grating




 6.Light & Medium duty steel grating



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 heavyduty, well resistance of strong impact on surface. 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. 

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.

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


Wanjie brand welded steel grating panels are manufactured by high-power pressure resistance welder controlled by computers.  

flat bar surface can be flat, serrated and I-type. We have more than 300 specifications.Wanjie steel grating panels are semi-finished products with nominal width and 5-7m in length. Under the process of cutting, edge wrapping and surface treatment, the panels can be made into platforms, ditch covers and stair treads.products have been largely exported and well received due to even surface, strong and beautiful welding spot,accurate size.
