High strength vandal resistant best quality steel grating clamp
Introduction of steel grating clamp
It's a series of metal bars positioned vertically,placed an equal distance apart and joined by cross members to form a rectangular or reticuline pattern.
1. Material
mild carbon steel,stainless steel,aluminum
2. Bearing bar
It's the vertically positioned bars.
Size:from 3/4"×1/8" to 7"×1/2"
Bearing bar pitch: from 15/16" to 38/16"
3. Cross bar
Used to secure the position of the bearing bars.
Cross bar pitch: 2" or 4"
4. Optional surface
Plain surface
Serrated surface
Surface Treatment:Untreated, Painting or Hot dip Galvanizing
Steel Grating standard:
China: YB/T4001.1-2007(YB/T4001.1-1998)
Britain: BS4592-1:1995
US: ANSI/NAAMM(MBG531-93)
Australia: AS1657-1992
Charaterristics:The installation has the advantages of simple construction, light weight, good impact resistance, good bearing capacity ability,rather large water displacement characteristics, corrosion and rust resistance.
Feature of steel grating clamp
1.Optimum water draining: Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron.
2.Hot-dip galvanizing: Good antirust performance,maintenance free and replacement free.
3.High strength: With strength and toughness far higher than those of cast iron,it can be used in the environment with large span and heavy load,such as the wharf and the airport.
