We sepcialized in welded bar grating for more than 10years. maily produce mild steel grating. for more price, cooperation or quality information, pls inform us to xtproppant@outlook.com. 

Welded bar grating for steel structure platform provides one piece grating with a flush top surface.  It is widely used for walkways, fire escapes, and decks where a non-slip surface is desired.  We will cut any stock grating to your exact sizes or can order special sized panels.

Welded steel grating technical parameters:

1.Material: 

① Flat-rolled steel: high quality low carbon steel, stainless steel, aluminum alloy steel. 

② Cross Bar: Q235A or optional 304 stainless steel twisted steel, square steel, round steel, flat steel.

2:Flat Bar Surface Shape: flat, serrated, I -shaped,

3:Flat Bar Specification: 

① Plane Flat Bar Specification: 

a Thickness: commonly 3mm and 5mm; 

b Height: commonly 25mm, 30mm, 32mm, 40mm, 45mm, 50mm, 60mm and so on. 

① I -shaped Flat Bar Specification: 

a, Thickness of both ends: 5mm; 

b, Thickness of the center: 3mm; 

c, Height: commonly 25mm, 32mm, 38mm, 44mm, 50mm and so on

4.Flat Bar Spacing: Two adjacent center bearing bar distance , commonly three sizes: 30mm, 40mm, 60mm. Dense steel grating spacing is less than 25mm. Steel grating is mainly used for demanding applications.

5. Cross Bar Specification: common specifications: 5 × 5,6 × 6,8 × 8mm.

6. Cross Bar Spacing: Center distance between two adjacent bar is typically 50mm, 100mm

7. Length of Steel Grating Panel:. General steel grating length ≥ 800mm. Trench cover for large span platform has a length of 3000-10000mm.

8. Surface Treatment: Electro-ga anized, hot ga anized , painting, dipped rust-proof oil. These treatment can play a role in preventing oxidation.

9. Steel Grating Shape: Square steel grating , rectangular steel grating , steel grating with round edging , V- groove decking , profiled steel grating , fan-shaped steel grating combined into hollow circular plate, semicircular steel grating , special shaped steel lattice panels, profiled steel grating

10. Packaging Methods:

① Strap Packaging: Generally for relatively common shape steel grating .

② Pallet Packaging: General packing for export.

③ Screw Rod Fixation: Using four screws through the steel grating aperture, locking screw
