Press-locked Steel Bar Grating serrated grating for extra safety

Pressure lock bar grating is a kind of high strength grating. It is a product featuring unique combination of uniformity and precision. It has light structure, elegant style, beautiful and natural design and it is maintenance-free. Press-locked steel grating is used in civilian and commercial buildings, theatres, subway, suburban railway, and other municipal engineering.

It exhibits the same strength, long life and openness as welded grating. Materials applied include mild carbon steel and stainless steel. It is also available in a serrated surface for extra safety.
