Galvanized steel grating, also known as hot-dip galvanized steel grating, steel grating after being produced, anti-rust treatment. There are two kinds of hot-dip galvanized and electro-galvanized points. Hot dip galvanized steel grating according to the manufacturing process, into pressure welding galvanized and pressure lock galvanized steel grating; galvanized flat steel surface according to the shape of the tooth into hot galvanized, hot-dip galvanized flat, I hot-dip galvanized and hot dip galvanized steel composite grating. HDG mark codenamed letter "G" may be omitted in the steel grating designator. HDG implementation of standards: GB / T 13912-2002 galvanized steel grating characteristics: 1, hot dip galvanized (flat pitch 30mm) flat pitch 30mm galvanized steel grating for the industry's most extensive use species. In the commonly used galvanized steel grating series, with the strongest impact on the surface force arrived. Using flat wide 65mm-200mm thick 5mm-20mm and other welded galvanized steel grating, for large freight yard, docks, mines, roads, bridges, etc., can carry large trucks through. 2, hot dip galvanized (flat pitch 40mm) flat pitch 40mm galvanized steel grating is the most economical and lightweight varieties. In the span of smaller occasions, is the best choice. For various occasions, especially aisle, sightseeing platform. 3, hot dip galvanized (flat pitch 60mm) flat pitch 60mm 50mm rail for hot galvanized for mining mineral mining industry to solve the problem of splash on the plate, often designated for mining plants. Galvanized steel grating appearance, durable: hot-dip zinc surface treatment it has a very good corrosion resistance, surface gloss appearance; ventilation, lighting, cooling, good slip resistance against product contamination. Widely used in petrochemical, power plants, water plants, sewage treatment plants, municipal engineering, environmental engineering and other fields platform, walkway, bridge, ditch cover, covers, ladders, fences, guard rails and other venues.
