hot dip galvanized grating

Hot-dip galvanized steel grating, also called hot-dip galvanized steel grate, is a grid-shaped building material welded horizontally and vertically by low-carbon steel flat steel and twisted square steel. Hot-dip galvanized steel grating has strong impact resistance, strong corrosion resistance and heavy load capacity, elegant and beautiful, and has excellent performance in municipal roadbed and steel platform construction projects. The extremely high cost performance is that hot-dip galvanized steel grating is widely used in the construction of new and old roadbeds to cover ditches and roads. The surface of hot-dip galvanized steel grating is treated with special hot-dip galvanizing, and its chemical and physical properties are stable, and it is not easy to be corroded and oxidized by air and microorganisms. Can significantly enhance the trench load capacity. prevent collapse. The hot-dip galvanized steel grating with a flat steel spacing of 3 cm has a greater impact resistance and has the characteristics of the largest span. The longer its service life, generally in the range of 40-50 years. If no destructive factors are involved, the hot-dip galvanized steel grating is a very good steel frame structure and load-bearing platform. Type: 1. Ordinary hot-dip galvanized grating After the load-bearing flat steel groove is cut, the flat section of the cross bar is press-locked and formed. The maximum processing height for the production of ordinary gratings is 100mm. The length of the grid plate is usually less than 2000mm. 2. Integral hot-dip galvanized grille The load-bearing flat steel and cross-bar flat steel have the same height, and the groove depth is 1/2 of the load-bearing flat steel. The height of the grid plate shall not exceed 100mm. The length of the grid plate is usually less than 2000mm. 3. Sunshade type hot-dip galvanized grille The bearing flat steel is opened with 30° or 45° chute, and the groove rod flat steel is grooved and pressed to form. According to different needs, gratings with other spacing and specifications can be delivered, and ordinary carbon steel, stainless steel, aluminum and other materials can be used. The height of the grid plate is less than 100mm. 4. Heavy-duty hot-dip galvanized grating The high flat steel and the horizontal bar flat steel are interlocked and pressed together under a pressure of 1,200 tons. Suitable for high-span load-bearing occasions. Use: 1. The characteristics of hot-dip galvanized steel grating are: high strength, light structure: the strong grid pressure welding structure makes it have the characteristics of high load, light structure, easy hoisting and other characteristics; beautiful appearance and durable. 2. Use of hot-dip galvanized steel grating: widely used in platforms, walkways, trestles, trench covers, manhole covers, ladders, fences in petrochemical, power plants, water plants, warehouse construction, sewage treatment plants, municipal engineering, sanitation engineering and other fields , guardrail, etc.
