Press-Locked Bar Grating

Bar-Grating-PressLocked Press-Locked Bar Grating Products

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. However, instead of welding the joints together, architectural press-locked grating products rely on the application of enormous hydraulic pressure that fuses the two close-tolerance slotted bars together. Permanent locking is achieved by forcing the deep crossbar into the notched bearing bar.

This type of grating can be manufactured from stainless steel, carbon steel, or aluminum.


The Benefits of Press-Locked Bar Grating

Press-locked bar grating is an extremely versatile product that can be used in a wide range of industrial applications. Industrial bar grating products like press-locked bar grating offer the advantage of superior lateral support, particularly when using press-locked steel bar grating (as opposed to the aluminum version). It also produces a smooth, clean look that is favored by architects and design professionals. What’s more, press-locked bar grating is durable and very easy to maintain, making it a reliable and long-term grating solution.
