Steel grating is welded 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 we can produce high quality gratings

withfirm welding,smooth surface and high strength.

1.material: low carbon steel,mid steel or stainless steel

2.Surface Treatment: Untreated, Painting or Hot dip Galvanizing

3.Specification of steel grating

(1)The shape of bearing bar: Plain type (may be omitted in the symbol of steel grating), Serrated type 

4.Tolerance of hot dip galvanized steel grating

The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm. 
The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar. 
Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not surpass

the end surfaces of two sides of grating 2mm.

5. steel grating application
