Low Carbon Steel Bar Grating Heavy Duty Non Silp Easy Install
Press Locked Steel Grating – Common, Integral
Common type:
After the grooving of bearing bar, the cross bar press locked and molded.
Maximum machining height of common steel grating is 100 mm, the length of steel grating is less than 2000 mm.
The standard height of bearing bar: 20 mm to 170 mm.
The standard thickness of bearing bar: 2 mm, 3 mm, 4 mm, 5 mm.
Integral type
The bearing bar of integral steel grating has the same height as cross bar. The grooving depth is 1/2 of bearing bar.
The height of the steel grating is less than 100 mm. and the length usually less than 2000 mm.
The standard height of bearing bar: 20 mm to 100 mm.
The standard thickness of bearing bar: 2 mm, 3 mm, 5 mm.
Heavy duty steel grating
Heavy duty steel grating is bit by bearing bar and cross bar in the 1200 tons of pressure under the molding. It is suitable for high load bearing occasions.
The standard height of bearing bar: 80 mm to 200 mm.
