Benefits of Welded Grating:
By pressing and welding to form a homogenous unit of all intersection points, high shear forces can be absorbed. Depending on static or dynamic loading, heavy-duty gratings can be provided for many applications depending on the clear span.
Material: Carbon Steel,Stainless Steel
Surface: Smooth,Serrated
Finish: Mill Finish, Black Primer, H.D. Galvanized
Material Standard:
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
Qindelin 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:
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, 60mm
Pitch 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.

Technical Terms Applied for Welded Bar Gratings
U = safe uniform load, psf
C= safe concentrated load, pfw
D = deflection, inches
E =modulus of elasticity,29,000,000 psi
F =fiber stress,18,000 psi
Material: ASTM A-569 standard
Defiection: Spans and loads to the right of the bold line exceed 1/4"deflection for uniform load of 100 psf which provides safe pedestrian comfort. These can be exceeded for other types of loads with engineer's approval.
Serratet Bars: For serrated grating, the depth of grating required for a specified load is 1/4"deeper than standard.
General: Loads and deflections are theoretical and based on static loading.
