Galvanised Metal Bar Grating ( China Grating Factory)

platform welded bar grating
Welded Steel Grating (Metal bar grating) can be defined as a series of metal bars positioned vertically, placed an equal distance apart and joined by cross members to form a rectangular or reticuline pattern. Typically manufactured from mild carbon steel, 6000 series aluminum and 300 series stainless steels, bar gratings are also available in specialty metal alloys to suit nearly any application


The vertically positioned bars are designated as the bearing bars. These bars range in size from 3/4"x1/8" for light pedestrian traffic to 7"x1/2" for extreme vehicular loads. Typically, the spacing of the bearing bars is indicated in sixteenths of an inch, measured from the center of one bar to the center of the adjacent bar. This center-to-center or "on center" spacing ranges from 7/16" to 19/16"(1-3/16") on standard grating products. Standard gratings are also available with wider spacings providing even greater open area, but should not be specified without consulting the manufacturer. Heavy Duty grating products are commonly manufactured with bearing bar spacings ranging from 15/16" to 38/16"(2-3/8") on center.


The bars used to secure the position of the bearing bars are commonly designated as the cross bars. Cross bar profiles vary according to the method of assembly and material selected. As with bearing bars, cross bar spacing is measured as "on center" spacing. The customary cross bar spacing is 4" on center. On special order, 2" on center and other special spacings are also available.

Spacing of Bearing Bars


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

40_.jpgBearing 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
