Press-Locked Bar Grating

Press-locked steel bar grating is a steel grate with a system of interlocking, perpendicular bars, it provides a smooth clean look ideal for architectural applications such as grilles, dividers and screens. It is used in the same structural applications as its welded steel and rectangular aluminum counterparts. Materials include carbon steel, stainless steel or aluminum. Spacings range from 7/16" to 1-3/16".

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.

Press-Locked Rectangular Aluminum 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.
