Series 3 (spacing 60mm) steel grating is designed specifically for the application and development of the mining industry varieties, it solves the mineral splash on the plate problem. This series of steel grating has a nominal size of 50 * 60mm through space to allow most of the spilled material wear off, thus ensuring a clean and safe plate surface, such products are often designated for use in the broken system board , conveying line walkways and ball mill, processing plant and operation station. Toothed steel grating is widely used; in petroleum, chemical industry, ports, electricity, transport, paper, pharmaceutical, steel, food, municipal, real estate and manufacturing. Since its establishment, more than by quality, reasonable prices, quality service, excellent technology, won the praise users! And eager to support each other with various user units, long-term friendly cooperation! Toothed steel grating is serrated on one side is flat steel welded together, with a strong anti-slip capacity, particularly for wet, slippery place, but also on oil platforms, etc., but its high price, consider the cost of procurement, serrated steel grating hot-dip galvanized surface treatment, has a strong and rust. Galvanized steel grating galvanized steel grating steel grating is later produced, to be anti-rust treatment. Hot dip galvanized steel grating and galvanized steel grating two kinds. HDG standards: GB / T 13912-2002 "hot-dip galvanized steel parts Technical requirements and test methods" Steel Grating as a new material, new products are being increasingly widely used, its superior performance and more good cost performance shows the prospects of its application. This paper discusses the performance of the steel grating, steel grating and a comprehensive selection of economic technical and economic analysis. In metallurgy, mining, petroleum, power and industrial sectors as well as some civilian areas, steel grating, as a new building is being increasingly widely used. The so-called new material, in fact, have decades more foreign history, but has been widely used for nearly 10 years only thing in China. But like aluminum doors and windows, as compared to conventional materials, it is customary or be referred to the new material. We often say that there are two kinds of galvanized steel grating: galvanized ---- also known as hot-dip galvanizing, he is at a high temperature to melt the ingot in put some supplementary material, and then the metal structure dipped galvanizing bath, the metal member attached to a layer of zinc layer. HDG has the advantage of his strong corrosion resistance, zinc coating adhesion and hardness better. After the product has galvanized increased weight, we often say that the amount of zinc, also mainly for hot-dip galvanizing for the. "Cold-plated" ---- "plating", that zinc solution by electrolysis, iron ions and zinc ions are replaced reflect generally without heating, the amount of zinc rarely encountered moist environment is very easy to rust . Galvanized Steel Grating suitable alloys, building materials, power plants, boilers. Shipbuilding. Petrochemical, chemical and general industrial plants, municipal construction and other industries, with air and light, non-slip, bearing capacity is strong, beautiful and durable, easy to clean, easy to install and so on. The new bridge steel grating has been widely used in domestic and foreign businesses, mainly for industrial platforms, ladders pedal, railings, access flooring, railway bridge side road, aerial tower platform, covered drains, manhole covers, road barrier , parking lots, offices, schools, factories, enterprises, playgrounds, Villa fence, can be used as homes outside the window, balcony rails, highways, railways and railings.
