Steel Bar Floor Grating

We are professional manufactuer steel grating forplatform,pavement, trestle bridge, Pedestrian overpass,steelladdersandtreads, trench cover, trash rack, guard railling, goodsshelves andothers, wildly used in shipbuild plant, boiler factory,oilrefinery, sewage treatment plant, power plant, port, port andsoon.All grating are processing in our workshop strictly accordingtoclients' requirements. 

1.Specification & Marks

2. Standards of steel grating

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

 
calculation formula of nominal width:

nominal width=bearing bar centers×numbers of centers+thickness ofbearing 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. thiskind 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.
HESLY welded steel grating panels are manufactured byhigh-power pressure resistance welder controlled bycomputers.  
flat bar surface can be flat, serrated and I-type. We have morethan 300 specifications.Wanjie steel grating panels aresemi-finished products with nominal width and 5-7m in length. Underthe process of cutting, edge wrapping and surface treatment, thepanels can be made into platforms, ditch covers and stairtreads.products have been largely exported and well receiveddue to even surface, strong and beautiful welding spot,accuratesize.
