Toothed steel grating from one side is serrated flat welded together, in addition to ordinary steel grating characteristics and uses also has a strong anti-slip capability, especially for wet, slippery places, offshore oil platforms. Toothed steel grating hot-dip galvanized surface treatment, has a strong anti-rust power. Toothed steel grating can be used as a drain cover and frame hinge connection, security, safety, easy to open. Toothed steel grating made of high strength steel, the steel grating with high strength: the strength and toughness is much higher than cast iron, can be used for docks, airports and other large span and heavy load conditions. This product has a large mesh with the best drainage: leakage area of ??83.3%, more than twice the iron. Product appearance: simple lines, silver exterior, modern ideas, saving investment material Province: large span, heavy load, low prices than cast iron; and save iron Gein stolen or crushed and replacement costs. Toothed steel grating Raw material: ordinary steel: Material Q235 common models are generally the material is generally 253 255 303 305,323,325,403,404 405,503,505,605,705 and other specifications. We use mainly flat steel slitting and cutting steel plate together. Toothed steel: Model and flat like an ordinary, except that the flat side has spiky teeth marks. Mainly due to slip. I type steel: flat sides thick in the middle and thin. Twisted steel: also called twisted square steel. Generally 5x5 6x6 8x8 square steel, twisted steel. Series 1 (spacing 30mm) steel grating is the most common type, the use of products across all industrial sectors, this series by steel grating bearing bars center distance of 30mm, in line with US standards, the entire steel grating series , has the strongest impact on the surface resistance. It is widely used in power plants, refineries, sewage treatment plants, silos, chemical plants, highways, airports and docks and other platforms, walkways and drain cover, stair stepping, etc. Steel grating teeth which can be used in wet, slippery places, especially for offshore oil platforms. Series 2 (spacing 40mm) steel grating is the most economical and lightweight, in line with British standards for fixed platforms, walkways and stairs specifications, in a small span of occasions, this is the best product, even in the transport equipment aisle Under that kind of load is no exception, but also can be used for warehouse shelves, panels pavilion, bridge, protective fence, sun screens and so on. Series 3 (spacing 60mm) steel grating is designed specifically for the application and development of the mining industry, breed, it solves the mineral splash on the plate of the problem. This series of steel grating with a nominal size of 50 * 60mm through empty, allowed most of the splashed material wear off, so as to ensure a clean and safe plate surface, this product is often designated by the broken system board , transmission line corridors and ball mill, processing plant and operating station. Toothed steel grating is widely used; in petroleum, chemical industry, ports, power, transport, paper, pharmaceutical, steel, food, municipal, real estate, manufacturing and so on. http://www.ganggeban20.com
