Steel grating cross arrangement of flat steel in accordance with a certain pitch and the crossbar (twisted square steel, square steel, round steel, flat steel, etc.), and welded into the middle with a square lattice of an iron and steel products, steel grating Main use to do the drain cover, steel platform boards, steel ladder treads. The crossbar generally use the twisted square steel. Steel grating generally use made of carbon steel, hot dip galvanized appearance, can serve to prevent the oxidation of. Can also be made of stainless steel. Grating with the ventilation, lighting, cooling, non-slip, explosion-proof performance. Commonly uses uses a series of classification of steel grating steel grating Model Expand classification packaging production standard steel grating surface treatment method of making steel grating price formula steel grating, stainless steel grating, platform steel grating 3 drain cover, steel grating, composite steel grating, plug steel grating, FRP grating, steel grating ceiling 9 Series classified according to the purpose of plug steel grating steel grating plate expand uses commonly used steel grating Model edit this paragraph packaging steel grating packaging, general bulk or packaged with bundling, which is mainly based on the customer may be very few and do not need to use the forklift handling general bulk. Conversely goods more generally packaged forklift loading and unloading will be more convenient, short, everything for customer convenience, product protection in transit produce 货损 prevail. Edit this paragraph production standards, YB/T4001.1-2007 standard (China 2007 steel grating the latest version of the steel grating standard); addition, the United States, the United Kingdom, Australia and New Zealand have their respective standards, but also in accordance with the British BS4592- 1-1995 and American ANSI / NAAMM (MBG531-88) and other standard production. Steel standards in accordance with GB700-88, GB1220-92. Edit this section steel grating surface treatment hot dip galvanizing, cold galvanizing, painting, dip anti-rust oil, dip, do not deal with.
