Press-Locked Bar Grating

With Press-Locked Grating the cross bars and bearing bars are notched and pressed together through a high pressure manufacturing process. The result is a bi-direction flush surface that assures a firm, rigid connection and makes it aesthetically appealing for architectural applications. It is available from stock in twp bearing bars heights, in plain or corrosion-resistant galvanized steel, or aluminum. A variety of other bar heights, bar spacings and materials is available by special order.

Press-Locked Rectangular Bar Grating is constructed with the two close-tolerance slotted bars bonded together (positioned every 2" or 4") using tremendous hydraulic pressure. Permanent locking is achieved by forcing the deep cross bar into the bearing bar. Both the cross bars and the bearing bars provide walking surfaces in the press-locked design.

Rectangular bar grating in either the swage-locked or press-locked styles is your best choice when lateral stiffness is required. The rectangular bar is also available in a serrated surface for additional safety.

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, although it is not recommended for rolling loads. 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.
