Galvanized Compound Steel Bar Grating Floor Composite Metal Steel
Grating With Checker Plate Grating
The compound steel bar grating is a perfect combination of steel bar grating and checkered plate,
featuring beautiful appearance and high solidity. When it comes to
the manufacture of compound steel bar grating, JG323/40/100,
JG253/30/100 and JG323/40/100 steel bar grating are most often used
as the base plate. Then, weld 3mm thick checkered plate upon the
base plate. After proper polishing and surface treatment, a good
condition compound steel bar grating is produced. In consideration
of different working conditions, the dimensions and materials of
grating and checkered plate can be customized.
Applications:
Compound steel grating is widely used in the platform, corridor,
bridge, well covers and stairs, fencing for petroleum, chemical,
power plant, waste treatment plant, civil engineering projects and
environmental projects. Because of its robust design and spanning
abilities, this kind of grating is extremely strong and safe for
the supportive structures on deckings, mezzanine floors and
elevated walkways.
Specification of Compound Steel Grating:
1)Type: SG323/40/100, SG253/30/100 and SG323/60/100
2)Standard: YB/T4001.1-2007, ANSI/NAAMM, BS4592, AS1657
3)Thickness: 3mm thickness is used as sealing; sometimes checkered
plate with thickness of 4mm, 5mm or 6mm is also used as sealing
plate according to customer’s requirements
4) Surface treatment: Hot-dip galvanizing, paint or other
anti-corrosive coatings are available, of which hot-dip galvanizing
is generally recommended
5) Application: Industrial platform, flooring and walkway, traffic
& steel structure
6) Notice: as thermal stress may cause shape distortion after
hot-dip galvanizing treatment, especially when choosing large
spacing grating, it’s not easy to flatten, so special attention
should
