Shaped trench cover trench cover supplier of steel grating trench cover made ditch (well) cover, with a variety of models to choose from to suit different load and span requirements. Widely used in municipal roads, garden facilities, residential areas, schools, stadium management and other different places. Depending on different occasions and different specifications of the ditch (well) cover, the surface can be hot dip galvanized, cold Coated (Galvanized) or no treatment. I. Introduction trench cover is mainly used for a number of factories and high-end residential use, mainly because the cement trench cover is often crushed, pavement has also been destroyed. Therefore, the use of steel grating trench cover made to fit different truck loads. Because trench cover simple construction, light weight, carrying, impact, rather bend do not break, large displacement, after the hot-dip galvanizing beautiful and durable, corrosion, has incomparable advantages of cast iron cover. And the use of the hinge connecting link or the use of hooks, etc., easy to open, and with anti-theft feature. In some high-end cell factories and widely used. Since 2000, China's trench cover market can be said to become more widely used in some municipal roads, garden facilities, residential areas, schools, stadiums, factories and construction sites have different applications. Country on steel grating products design requirements, its steel grating steel grating class products and related instructions. Second, the classification of a product, usually we can make based on different materials, into the trench cover hot-dip zinc trench cover, stainless steel trench cover, trench cover, etc. spray. 2, according to the trench cover shape can be divided into: general type trench cover, U-shaped trench cover, trench cover and tube-type trench cover can be opened. 3 trench cover product size three, use: 1, trench cover flat direction bearing (support) direction, according to the trench (Wells) wide gaps remain flat fixed length L; 2, according to the ditch (well) long layout, Take in line with standard processing modulus plate width 995mm, leaving a gap between the plates 5mm; 3, ditch (well) remaining less than one meter long section modulus given by size; 4, according to the ditch (well) and carries a wide selection of steel grid requirements grid models. 5, recommended to choose a standard size trench cover design and construction, and other specifications can be customized. Four, flat material: Material for Q235A or stainless steel, ordinary flat 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 AOpen factory outlets, etc. Because so many of the specifications. Rails: Material for Q235A or 304 stainless steel round bar, twisted steel, square steel or six angles. Twisted square steel plate garden by the side of the mold by drawing and twisted together, their common specifications are 5 * 5,6 * 6,8 * 8mm and so on. Concrete: Material for reinforced concrete, strength of C25 / C30 / C35. Load-bearing capacity, low cost, easy maintenance. Five, features a beautiful 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, 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, 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. [2] The product is simple construction, light weight, carrying, impact, rather bend do not break, large displacement, after the hot-dip galvanizing beautiful and durable, corrosion, with cast iron cover not like advantages. Using a hinge connecting link or the use of hooks, etc., easy to open, and with anti-theft feature. Six steel grating trench cover classification usually consists of a fixed frame and the activities of steel grating trench cover composition, may be needed, coupled with tightening fittings and anti-theft device. GT type trench cover: GT type common side ditch, ditch transverse steel grating trench cover steel grating trench cover the roadway into the side ditch ditch lid cover and transverse directions according to dealers. Carrying flat and perpendicular to the direction dealers become side ditch cover, bearing flat and parallel to the direction dealers become transected ditch cover. GU type ditch cover: GU-shaped groove steel grating trench cover for the majority of ordinary concrete masonry along the mouth of the ditch without using U-shaped trench cover is very simple, economical, no special groove edge. T6-14 load when the Gouyan recommend buried angle, but also can be prefabricated blocks to build a U-shaped ditch ditch, effectively preventing the leakage of sewage into the ground. Needs over the car, this U-shaped steel grating trench cover only applies to GM type side ditch trench cover: Road Park and other municipal facilities, water wells, dust shafts, wells, water wells and other water supply and drainage wells, porosity, people Cover the hole, can use GM-type wells steel grating cover, GM-type wells steel grating cover is generally designed to be flip, headstock angle usually turn to 110 degrees. Steel grating with a rudder angle of the only security but also simplifies the procedure of reinforced concrete trench cover: roads, municipal use, size freely adjustable, adjustable intensity. Seven chosen a selection of sizes for use on road traffic sidewalk, driveway, parking steel grating, dock or building ground trench cover, because of the different loads and dealers direction, the design and selection type should be considered the actual situation. 2, for the ditch on the road and crossing the ditch cover (dealers carrying flat direction parallel to the direction), not only to consider the wheel pressure, impact, need to prevent the risk of bouncing shift trench cover, you must ditch Cover and angle, support beams fixed (you can use fixed or welded steel grating installation clips). Selection of light load: 25 tons / m2; car, pedestrians campus residential garden, park, underground parking and other kitchen heavy: 70 t / m2; 20 tons of plant automobile traffic, general highways, main roads roadside parking Field and streets and other super-heavy: 140 t / m2; heavy-duty trailer, container forklifts, cranes and airplanes Supply category: Spot / made whether stock: Yes Origin: Anping main map Source: real shooting Material: iron, stainless steel surface treatment: galvanizing, painting shape: according to customer needs technology: welding Model: 50 * 100 100 * 200
