Twisted steel serrated galvanized steel grid bonding steel grating steel grating

Twisted steel serrated galvanized steel grid bonding steel grating steel grating steel grating has high strength, compression capability, light structure characteristic: As the product uses strong pressure welding grid, forming a welding technology that of its high carrying capacity, and facilitate loading and other characteristics; beautiful appearance, durable; steel grating standard surface hot-dip zinc surface treatment it has a very good corrosion resistance, surface gloss appearance; ventilation, lighting, cooling, explosion-proof, non-slip properties; against product contamination. 1, steel: the material is Q235A or stainless steel, a common plane type, tooth type and section I slip type. Common specifications 20 * 5,25 * 5,25 * 3,32 * 5,32 * 5,40 * 5,40 * 3,50 * 5,65 * 5,75 * 6,100 * 8,100 * 10 and so on. 2, rail: Material is Q235A or 304 stainless steel round bar, twisted steel, square steel or six angles. Twisted square steel plate garden by the side by the die drawing and twisted from its common specifications are 5 * 5,6 * 6,8 * 8mm and so on. Drain cover Features: 1, appearance: simple lines, silver exterior, modern trends. 2, the best drainage: leakage area of ??83.3%, more than twice the iron. 3, hot-dip galvanizing: rust-proof and strong, maintenance and replacement. 4, anti-theft design: hinged lid and the box with the connection, security, safe, easy to open. 5, saving investment: large span, heavy load, the lowest ratio of iron and saves replacement costs stolen or crushed. 6, high strength: strength and toughness is much higher than cast iron, it can be used for terminals, airports and other large span and heavy load environment. 7, specifications: meet the different environmental loads, span, size and shape desired. The product is simple construction, light weight, carrying, impact, rather bend do not break, the displacement of large, after the hot-dip zinc treatment beautiful and durable, anti-corrosion, with a cast iron cover not like advantages. Using a hinge or hook-link connection, etc., easy to open, and with anti-theft feature.
