Steel Grating. It is also the most widely used type.
Steel gratings trench cover is produced through automatically resistance welded. The bearing bars and cross bars are resistance welded under high heat and pressure to form a permanent joint. This technology can not only ensure the rugged structure of welded steel grating, but also can retain a smooth and flat surface, which is easy and free to walk.
Steel gratings trench cover can be made of various materials, such as carbon steel bars, aluminum steel bars and stainless steel bars.

But the serrated steel grating have better skid resistance property than the smooth surface.
