introductions:
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. Instead of welding the joints, however, tremendous hydraulic pressure is used to bond the two close-tolerance slotted bars together. Permanent locking is achieved by forcing the deep cross bar into the notched bearing bar.
Pitch of loading bars Center to Center: 11.1mm & its multiples; 20mm & its multiples; 25mm & its multiples

The loading bar punched with slots and flat cross bar are press together by a large capacity hydraulic machine. And then pressed-locked grating is formed. Surface treatment can be galvanization, bitumen dipped or painted.
Compared with press-welded grating press-locked grating has more advantages as below:
Compared with press-welded grating press-locked grating has more advantages as below:
1) Excellent force transfer in horizontal direction and material saving
2) Ensure clean, even and smooth surface, adding artistic beauty to appearance
3) Diversified loading bar and inserted bar pitch can meet various needs of customers
4)Enjoy the same loading capacity, lifetime and mesh pattern with electro forged welded grating
