A hot dip galvanized grating Overview: galvanized grating is in accordance with a certain distance and crossbar (twisted steel, square steel, round, flat, etc.) with a flat cross arrangement, and welded into An intermediate steel products with a square lattice and then again its deep processing of steel products by means of a hot-dip zinc corrosion process. Because usually adopts galvanized steel grating with a lower cost and better corrosion dual advantages, so the industry often uses hot dip galvanized steel grating steel grating. Second, galvanized grating production standard galvanizing production standards grill plate: YB / T4001.1-2007 standards and YB / T4001-1998 standard; three, galvanized grating characteristics: galvanized grid grid-saving construction materials reduce the investment period is durable and easy to save modern style structure against product contamination reduce drag, lightweight design is simple good ventilation, lighting, cooling, explosion-proof, non-slip performance characteristics. Fourth, galvanized grating Uses: Widely used platform petrochemical, power plants, water plants, sewage treatment plants, municipal engineering, environmental engineering and other fields, walkway, bridge, ditch cover, covers, ladders, fences, guard rails, etc. Fifth, galvanized grating classification 1, according to the tooth can be divided into flat shapes galvanized grating, galvanized grating plane type and I-type hot galvanized grating. One of the most commonly used type of hot galvanized flat grid sheet, hot dip galvanized using tooth grating at the higher slip requirement, while the decorative ceiling, which do not require any load but requires aesthetic usually hot galvanized lattice type I grid. 2, according to the production process galvanized grating into bonding grill plate and pressure lock grating. Pressure welding is the crossbar grille using twisted square steel grating, mainly used in load-bearing platform in one direction; the pressure lock crossbar grille is also used flat grill plates, mainly in the two sides of the bearing platform. 3, according to the series of hot-dip galvanized steel grating can be divided into the following three categories: Series 1 (spacing 30mm) galvanized grating is the most common type, the use of the product throughout the various industrial fields, such series grill plates Loaded flat center distance 30mm, in line with US standards, the entire grating series, with 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) galvanized 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 Under that kind of load transport equipment aisle 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) galvanized 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 grid sheet having a nominal size of 50 * 60mm through-air, to allow most of the splashed material wear off, thus ensuring a clean and safe plate surface, the product is often designated for use in crushing system board , transmission line corridors and ball mill, processing plant and operating station. Six, galvanized grille crossbars: Material for Q235A or 304 stainless steel round bar, twisted steel, square or hexagonal steel and flat steel. Twisted square steel plate garden by the side of the mold by drawing and twisted together, their common specifications 6 * 6,8 * 8mm seven, galvanized flat steel grill plate: Q235A material usually ordinary flat. Model main 25X3mm, 30X3mm, 32X3mm, 25X5mm, 32X5mm, 40X4mm and 50X5mm of flat steel. Eight, galvanized grating installation: galvanized grating available welding clamp mounting and installation methods. Grating installation space is generally 10MM. Each installation must pay attention when installing solid and reliable, you should always check to prevent the mounting clip loose in the vibration source close to the best steel grating welding or add a rubber pad. 1, suitable for permanent fixed welding without disassembly of parts, such as equipment around the platform, while the use of the mounting clip has not destroy the zinc layer and easy removal features. Fixed welding methods are: steel grating on each corner of the first root of flat steel, weld length is not less than 20mm, height not less than 3mm of fillet welds. If you are directly or steel grating treads on the supporting steel welded, then weld zinc-silver paint should be brushed twice rust.
