Welded Steel Grating used for stair treads and various floor
Mild steel - We utilize a high quality mild steel for load bearing bars, which exceeds the strength of ASTM A36, BS4360 Grade 43A and JIS G3101 SS400, KSD3505 SB41. This is particularly beneficial where a floor is subjected to wheel loads, as deflection becomes a subordinate consideration to the ability of the load bearing bar to withstand high stress. Stainless Steel – Floor can also be manufactured from stainless steel. The normal grade used are 304 and 316, but other grades can be considered upon request.
Manufacturing Standards HongSheng steel gratings are designed and manufacture in accordance with relevant international standards. The figures found in the load and deflection tables are calculated in compliance to national standard, while the manufacture conforms to the requirement of international standard.
Common sizes of our steel grating bar:Pitch of Bearing Bar A center distance between the two bearing bars adjacent to each other. Common pitch : 30mm & 40mm Other : 12.5mm, 15mm, 25mm, 60mmPitch of Cross Bar A center distance between the two cross bars adjacent to each other. Standard pitch : 50mm & 100mm.
NOTE: Difference spacing of bearing bar & Cross bar can also be manufacture upon request.Uses: Electro-Forged Steel Grating can be used as industrial trucks, stair treads and various floorings.
