Press-locked grating is also called pressure locked grating or press-locked steel bar grating. Basically, the press-locked grating have the same load capacity with the welded steel bar grating. The difference between press-locked grating and welded steel bar grating are joint connection technology and cross bars.
Cross bars of welded steel bar grating are twisted square rods and the bearing bars are rectangular bars or I type bars. Both the bearing bars and cross bars of press-locked grating are rectangular bars.
Compared to welded steel bar grating, which is produced through resistance-welding process, the press-locked grating is constructed with the two close-tolerance slotted bars bonded together by tremendous hydraulic pressure. This production can let press-locked grating be a permanent locking.
Press-locked grating and swage-locked grating has excellent lateral stiffness, which can be used in some special applications. And the serrated surface is available for press-locked grating.

Classification of press-locked grating
Press-locked grating has main four types because they have different bearing bars and cross bars.
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.
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.
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.
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.
