20 years of steel grating industry experience
：钢格板是用承载扁钢和横杆依照必定的距离进行正交组合，通过焊接或压锁加以固定的开敞式钢构件；横杆通常选用通过扭绞的方钢、也可选用圆钢或扁钢，原料分为碳钢和不锈钢。 Steel grid plate : The steel grid plate is an open steel member that is orthogonally combined with a flat steel bar and a cross bar according to a certain distance, and is fixed by welding or press lock; Round steel or flat steel can be selected. The raw materials are divided into carbon steel and stainless steel. Steel gratings are mainly used for steel structure channel boards, trench covers, step boards for steel ladders, and building ceilings.
Introduction: Steel grating is usually made of carbon steel, and its surface is hot-dip galvanized to prevent oxidation. Can also be made of stainless steel. The steel grating has the functions of ventilation, lighting, heat dissipation, non-slip, explosion-proof and so on. The steel grid is interspersed with flat steel according to a certain distance and crossbars. It can be welded by a pressure welder or manually to a steel product with a square grid at the base. The steel grid is mainly used as a gutter cover. , Steel structure channel boards, step boards for steel ladders, etc. The crossbar is usually made of twisted square steel.
Steel grating is suitable for alloys, building materials, power stations, boilers. shipbuilding. Petrochemical
, Chemical industry and general industrial plants, municipal construction and other industries, with ventilation and light transmission, non-slip, strong bearing capacity, beautiful and durable, easy to clean, simple installation and other advantages. Steel gratings have been widely used in various industries at home and abroad. They are mainly used as industrial channels, ladder pedals, handrails, aisle floors, side railroad bridges, high-altitude tower channels, gutter covers, manhole covers, road barriers, and three-dimensional Fences for parking lots, offices, campuses, factories, enterprises, sports fields, and garden villas can also be used as exterior windows, balcony railings, highway, railroad railings, etc.
Series classification of steel grid plates with different uses: Series 1 (distance 30mm) Steel grid plates are the most commonly used type, and are used in a wide range of industrial categories. The load flat steel base distance of this series of steel grid plates is 30mm, which is in line with the United States. Standard rules, among all the steel grid plate series, has the strongest resistance to external impact. It is widely used in power plants, refineries, sewage treatment plants, granaries, chemical plants, and public utilities.
Roads, airports and dock channels, walkways and gutter covers, stair steps, etc. The toothed steel grating can be used in wet and slippery places, especially for offshore oil production channels. Series 2 (distance 40mm) steel grating is the most economical and lightweight type. It conforms to the standard of fixed channels, walkways and stairs in the UK. It is the most ideal product for small spans, even in transportation equipment aisles. That kind of load is no exception. It can also be used to make shelves in warehouses, panels of pavilions, trestle bridges, protective gates, sun curtains, etc. Series 3 (60mm distance) steel grating is a type developed especially for the mining industry. It deals with the problem of deposits falling on the surface of the plate. This series of steel gratings have a nominal size of 50 * 60mm, which allows most of the splashing material to penetrate, and then ensures the cleanness and safety of the surface. This product is often designated as the surface of the crushing system. , Aisles on conveyor lines, ball mills, processing plants and operating stations. As a new type of engineering materials, steel gratings are mainly used as channels, trestles, bridges, highway guardrails, trench covers, gates, gates and other equipment in the fields of metallurgy, power, ships, municipalities, petrochemicals, transportation, building materials, and national defense. . At present, the annual demand for steel gratings in China is about 270,000 tons. Therefore, the market prospect of steel grating is very broad.
