material

 

1.Bearing bar&cross bar steel grade is Q235 which's in line with GB/T700.Other material can also be used afternegotiation.

 

 

 

2.Hot-rolled flat bar,hot-rolled strip or cold-rolled strip silt by slitting shears are available for bearing bar.

 

 

 

3.Tolerance for the size of hot-rolled flat bar should be in according with the standard of YB/T4001.1-2007.

 

 

 

4.Hot-rolled flat bar,hot-rolled strip or cold-rolled strip silt by slitting shears are avallable for serrated bar.There would be 5 teeth at least within 100mm length.

 

 

 

5.The size of section & processional moment of section should be in according with the standed of YB/T4001.1-2007.

 

 

 Bearing bar centers at 20mm: 

 This kind of fine mesh steel gratings have strong 

 load ability and also can prevent the access of 

 sundries of 18mm in diameter. This kind of gratings 

 fit for pedestrian deck, walkway and ditch covers 

 which require high security

  Notes: common welding standard: single-side full welding every 6 bearing bars

 Bearing bar centers at 30mm: 

 This kind of steel grating is the most commonly

 used in projects with American, Australian, Japan

 standards are available. This kind of gratings are

 featured well by heavyduty, well resistance of 

 strong impact on surface. this kind of steel 

 grating fit for all kind of industrial platforms.

 

 Notes: common welding standard: single- side full welding every 5 bearing bars

 Bearing bar centers at 40mm: 

 light grating and very economical. This 

 kind of gratings fit for fixed platforms, 

 walkway, and stair treads and British, 

 German,French and Japanese standards 

 are available. The products most commonly

 used for Belt corridor, storage shelf,Attic 

 panel, trestle, guardrail, sunshade gate, etc.

 notes: common welding standard: single- side full welding every 4 bearing bars

 Bearing bar centers at 60mm: 

 This kind of steel gratings are especially 

 used for mining industries. It can solve 

 the problem that mineral splashing down 

 and stacks on the walkway. This product

 usually used for mineral miningand 

 processing and it is the best choice for 

 workshop, meeting room and suspended 

 ceiling of stadium in terms of it's light weight.

 notes:common welding standard: single-  side full welding every 3 bearing bars

Our projects

  

This is our project of steel grating ,it can be used to many aspects just like:

Installation of steel grating:

1.Welding & using saddle clips are two ways for installation of grating. The welding is suitable for those places where there is no need to move or dismental,for instance,the flooring around the machines. However,using saddle clips are featuring in easy installation & saving zinc layer.

2.Regarding welding installation, angle wolding would used at the first bearing bar of every corner,which the welding length is no less than 20mm,&the height is no less than 3mm.

3.Saddle clip composed of a top plate,a hold down & a M8 bolt, is suitable for all kinds of steel gratings installation.

4.Regarding saddle clip installation, at laest four sets of saddle clips would be used in one pc grating.It would be better using more in the staddle for those gratings with a bigger span.
