Special Shape Steel 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
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.
A).Type of Grating
Specify the type of grating required by reference of our four main
types of products: Plain steel grating, serrated steel grating, I
bar steel grating.
|Plain Bearing Bar||Serrated Bearing Bar||"I" Type Bearing Bar||"I" serrated Bearing Bar|
-Nominate the size of bearing bar and cross bar.
-Nominate the pitch of bearing bar and cross bar.
-Nominate the size of the steel grating panel.
-Nominate whether banding is required.
-For non standard panels, nominate dimension for length and width
of individual panels.
-Where large areas of flooring is to be covered, provide:
i) shop drawings of grating floor zone.
ii) detail drawings of beams, pillars and their joints.
iii) setting positions of stairs and procedures of stairs, railing
piping and etc.
iv) sizes and locations of cutouts, kick plates and nosing.
-For stair threads, select from our ranges of standard types and
nominate dimensions and quality. Our recommended length and widths
should be nominated for economical orders.
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 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
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 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
Notes:common welding standard: single- side full welding every 3
