Trench 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, strong, maintenance and replacement. 4, anti-theft design: with a hinged lid and box connection, security, safety gullies Grate wholesale price, easy to open. 5, saving investment: large span, heavy load, the lowest ratio of iron and saves the cost of replacing the stolen or crushed. 6, high strength: strength and toughness is much higher than cast iron grate gullies can be used for docks, airports and other large span and heavy load conditions. 7, specifications: meet different environmental loads, span, size and shape desired. Steel grating cover Itai an analysis of different materials, better SMC / BMC molding board substrate material covers the overall performance, but is short fiber reinforced materials, limited enhancement. Reinforced with steel grate gullies manufacturers, due to the interfacial bonding of metal and non-metallic materials and different thermal expansion coefficients and defective product for use on motor vehicles, their post-carrying capacity can not be evaluated; 2, layered composite plate covers not unsaturated resin as matrix material reinforced with continuous glass fiber composite material covers the plate, because the structure using pot grate structure gullies size, material force uniform, and the use of continuous fiber reinforced, not steel reinforced, composite materials are materials, carrying capacity and carrying capacity of the covers of the late protection, from the perspective of the carrying capacity and longer service life; stratified composite plate covers, outdoor part is resistant, anti-aging materials, vehicles from rolling resistance and anti-aging perspective, life is relatively long. Grate road gullies, Asahi Connaught wire mesh (certified), gullies grate provided by Asahi Connaught Anping Wire Mesh Products Co., Ltd. Asahi Connaught Anping Wire Mesh Products Co., Ltd. (www.wangpian1688.com) Hebei Hengshui, the wire mesh of the leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Snow in Asahi Metal Mesh leadership with the staff warmly welcome all inquiries negotiations to create Asahi promise a better future wire mesh.
