Made of steel grating trench cover, please note here that the steel grating to do, because as a trench cover drainage ditches on the cover, there are a variety of materials, cast iron manhole covers, ductile covers, etc. These materials drainage trench cover because the weight of heavy steel plate, easy to lose, gradually being replaced by steel grille. Trench cover this material, there are three forms, one is ordinary trench cover, one is theft trench cover, the last one for the special requirements of the design of CU-type trench cover. An ordinary trench cover can be applied in any situation steel drain cover what the specifications, it uses welded steel grating, light weight construction is simple to install, load, impact good, rather bend do not break, displacement of large, heat After galvanized beautiful and durable, corrosion and rust, has incomparable advantages of cast iron trench cover, two, trench cover theft is common around the trench cover the theft of welding iron frame, steel grid plate with hinged drainage, etc. steel plate price per square meter, making it easy to open the measurement of drainage steel plate size, and with anti-theft feature. Can effectively resolve the unnecessary loss covers lost caused. Three, GU trench cover you for most ordinary concrete ditch along the mouth puzzle without using U-shaped trench cover is very simple, economical, no special groove edge, load T6-14, the proposal on Gouyan buried angle, also can be prefabricated blocks to build a U-shaped ditch ditch, effectively preventing the leakage of sewage into the ground, you need to cross the car, this U-shaped steel grating trench cover only applies to side ditch. I plant in accordance with customer requirements, production of different load, span steel grating products, according to the actual requirements of the selected, according to the use of different occasions, different materials provided trench cover, in addition to ordinary galvanized outer trench cover also provide other materials such as stainless steel processing trench cover, etc. Technical parameters covers board: Test load: Heavy 400KN, P-type 250KN, light 125KN; bending strength: the impact strength of 22MPa averages: Average 10J / m2; Compressive Strength: Average 25MPa; Tensile Strength: Average 10MPa; elasticity modulus: Average 1000MPa; water absorption: 1%; Acid resistance: the sample of 20% sulfuric acid solution soak 48h; no surface corrosion mass loss of 1%.
