Welded bar grating is also called metal open bar grating. It can be made of various materials, such as carbon steel, aluminum steel or stainless steel. The bearing bars and cross bars are welded under high heat and pressure to form a permanent joint. And there are two types of the steel bar grating: smooth and serrated steel bar gratings. Smooth surface steel bar grating, also called plain steel bar grating, is more popular than the serrated surface steel bar grating. But the serrated steel grating have better skid resistant property than the smooth surface steel bar grating.
