{dede:global.cfg_gsname/} | Updated: 2020-01-06 02:35:00
As manhole covers are more and more valued by more and more people, the quality of manhole covers on the market is getting higher and higher, and product types are more and more. Manhole covers of different sizes are allocated for use in different regions. Resin manhole covers are generally used in municipal and electric power applications and have a wide range of functions, so the specifications of resin manhole covers are different.
BMC, SMC resin and other materials are used for one-time compression molding at high temperature and pressure. This product has the advantages of high density, high hardness, high pressure, corrosion resistance, aging resistance, light weight, and beautiful appearance. According to the inspection of the national authority, the higher bearing capacity is more than 50 tons, and all indicators exceed the national standard, and even exceed other domestic composite manhole covers. More suitable for municipal engineering, fast lane use. The products sell well all over the country and are exported to South Korea, Taiwan, Spain, Saudi Arabia and other countries and regions. It is an ideal substitute for cast iron manhole covers. The polymer composite manhole cover developed by our company has high strength, low price and beautiful appearance. Because there is no recycling value, the problem of theft of the manhole cover is completely solved.
Product advantages:
High standards: Strictly implement the national standard of the People's Republic of China "GB / T23858-2009 inspection manhole cover" and the European standard EN124: 1994 "vehicle and pedestrian area water cover
Standard for Plates and Manhole Covers.
Light weight: only about one third of cast iron, which is much lower than the weight of the cement manhole cover under the same load, which is convenient for transportation and installation and greatly reduces labor intensity.
High strength: BMC block molding compound with reinforced skeleton, BMC composite manhole cover produced by high temperature and high pressure, the test load reaches F400KN; HZ-SMC sheet molding compound
Production of high load (50KN-900KN) SMC composite manhole cover, test load reaches F900KN
Appearance: The pattern design on the surface of the inspection well cover is exquisite. It can be customized according to user requirements and made into various colors to beautify the urban environment.
Anti-theft property: This synthetic material has no recycling value and is naturally anti-theft. It also has a locking structure to prevent theft of property in the well.
Weather resistance: The product uses high molecular weight, high chemical stability polymer materials as raw materials. Through scientific formula, advanced technology and perfect technical equipment, the product can be used normally at -50 ° C- + 150 ° C.
High accuracy: As the product is molded by high temperature molding, the gap between the cover and seat is small, which overcomes the disadvantages of "running, jumping, ringing" of cast iron and cement manhole covers, and improves road traffic capacity and driving comfort.
Corrosion resistance: The product has been tested by the National Chemical Building Materials Testing Center. It has corrosion resistance, acid and alkali resistance, anti-aging index of more than three levels, and long service life.
Good after-sales service: strictly enforce the warranty policy of the product under the premise of non-human damage and correct use.
