Steel grating is a kind of widely used grid products. They are used in various industrial fields and has the strongest resistance to surface impact.
According to the shape of the surface,they can be divided into tooth-shaped steel grating, pressure welded steel grating, I-type steel grating and composite steel grating.

According to the surface treatment,they can be divided into hot-dip galvanized steel grating, spray paint steel grating, stainless steel grating and original steel grating.

Cross bar spacing:

30- 150 mm (center distance)

Crossbar Size:Generally 5 x 5 twisted rod

6 x 6 twisted rod

Bearing bar Size:

Usually 20 x 3 mm ~ 100 x 7 mm

Bearing bar spacing:

30,31,32.5,34.5,35,40 mm (center distance)

Bearing bar type:

P refers to common plain type

S refers to reinforced anti-skid serrated type

I refers to load bar with I- shape section

Surface Treatment:

G refers to hot- dip galvanizing (as default)

P refers to dip painting

U refers to no surface treatment
