Product Description

~1.Steel grating material:carbon steel or stainless steel
 
2.cross bar pitches:maybe *****0mm,of which *0mm,*6mm and **0mm are recommended.
 
3. Galvanized steel grating  is made by the world first-class equipment,which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high tension resistance weldingring which is controlled by computer.so we can produce high quality gratings with firm welding,smooth surface and high strength.
 
4.Surface process of gratings: there are three types:hot-dipped galvanized ,electro-galvanized and spraying brushing and soaking.anti-acid and alkali corrosion capacity the range PH6 to PH*2.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property

NOTE
Difference spacing of bearing bar & Cross bar can also be manufacture upon request.
 

~6.Packing conditions of steel grating:normally packed in pilling up ways with two pieces of square wood on both upperand bottom sides.there are four or six pieces of M*0 long bolt penetrading the gratings and screwing together.it is suitable for loading and unloading by fork-lift and crane.

We produce three kinds of steel gratings, they are Plain Style Steel Grating, Serrated Style Steel Grating and I Bar Type Steel Grating. They are widely used in steel structure platforms, stair treads, sidewalks, drainages and well covers etc. We can design and manufacture standard steel grating and in customized shapes per client's requirements.
