Rain Water Hot Dipped Galvanized Platform Floor Steel Grating 32mm x 5mm Heavy Duty
1. Full-locked grating. Both the bearing bars and cross bars are notched and have the same height. They are interlocked with one another under extreme pressure.
2. Heavy-duty pressed grating. Both the bearing bar and cross bar are notched, but they have the different heights. The bearing bars are higher than the cross bars and they are interlocked with each other also at a high pressure.
3. Press-locked grating. Only the bearing bars are notched and the cross bars are common plain steel. They have different height and are locked with each other at a very high pressure.
4. Louver grating. The notches of bearing bars are at a angle of 30° or 45°. The cross bars are insert into the bearing bars before being pressed. This type is widely used in the places where the privacy is very important. It can also be used as sunshade of the buildings.
With Press-Locked Steel Bar Grating the cross bars and bearing bars are notched and pressed together through a high pressure manufacturing process.
Press-Locked Steel Bar Grating is often desirable because of its clean, smooth look and excellent lateral support. It exhibits the same strength, long life and openness as welded grating.Press-locked bar grating features a system of interlocking perpendicular bars that offer the same degree of strength, durability and openness as welded bar grating. Permanent locking is achieved by forcing the deep cross bar into the notched bearing bar.
