China Manufacturer Factory Supply Galvanized Steel Grating for Industrial Flooring, Walkway, Catwalk, Driveway

Bar grating is made up of parallel bars that are connected together with perpendicular bars. The bars are most commonly connected through welding, however, there are other ways of joining the bars together. Alternatives include riveting, close meshing, press-locking and more. The most economical method of joining is determined by the materials being used and the thickness of the bars.

Bar grating can be made out of a variety of different materials but is most commonly made from steel or aluminum. It has a very high ratio of strength-to-weight and a lot of open space, making it a widely used option for industrial flooring. However, it is also used for things such as fire escapes, street drains, and bridges.
