Building Material Heavy Duty Hot Dipped Galvanized Stainless Steel Grating for Drainage Trench/Drain Cover
Steel bar grating is also known as steel grating. Steel grating is made up of parallel bars that are connected together with perpendicular bars. The bars are most commonly connected through machine pressure welding or manual welding, as the case may be. However, there are other ways of joining the bars together. Alternatives include riveting, close meshing (swaging), and press-locking. The most economical method of joining is determined by the materials used and the bars' thickness. Steel bar grating is usually made out of carbon steel orstainless steel. 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.
At Tec-Sieve, both press welded steel bar grating panels and press locked steel bar grating panels are manufactured. Our press welded steel bar grating panels are ideal for most industrial applications, including without limitation the oil and gas industry, the petro-chemical industry, the mining industry and in power stations, so now we focus on our press welded steel bar grating panels in the following.

Application of Steel Floor Grating
1) It can be used in urben construction as drainage trench cover to drain water and keep ground dry.
2) The serrated steel gratings will be used in the port, parking lot, farmland and other places to be walk platform for pedestrian and vehicles access and passing.
3) Forge-Welding gratings also will be used for industry platform, power plant, water treatment industry, tower platform, etc.
4) Serrated steel gratings also be guardrail for garden, villa, balcony, highway, etc.
