galvanized steel grating

1) material:carbon steel or stainless steel

2) cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.

3) 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 welding ring 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 PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.

5) 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 M10 long bolt penetrading the gratings and screwing together.it is suitable for loading and unloading by fork-lift and crane.

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

Steel Bar Grating, also known as Welded Steel Bar Grate is extremely strong and durable for all 

load bearing applications and is primarily used for pedestrian and light vehicle traffic. Steel bar 

grating is available in a variety of bearing bar spacing and thicknesses depending on applications 

and load requirements. Available in either smooth top or serrated for slip resistance.

Serrated/non slip                                                                       plain/flat

  welded                                  pressure locked          swage-locked
