Product advantages:
(1) the service life is long: the composite trench cover plate's anti-aging index reaches more than three grade, and the service life is longer.
(2) High strength: the product is made of polymer material, reinforced framework and molded at high temperature. The test results meet and exceed the new CJ / t211-2005 standard issued by the Ministry of construction of the people's Republic of China, and the product has high strength
(3) Beautiful appearance: the surface pattern design of the composite trench cover plate is exquisite, which plays a good role in beautifying the urban environment.
(4) The product is light: the product made of composite material is inconvenient, has good toughness, and is more portable, convenient for transportation, installation and maintenance, so as to reduce the labor intensity and save the maintenance cost.
(5) The product is anti-theft: the synthetic material has no recycling value, so it can effectively reduce all kinds of personal and property accidents caused by the loss of ditch cover plate.
(6) High product precision: the cover seat seam gap of the product molded by high temperature molding is smaller, and the sealing performance is better, and the noise problems such as "running, jumping and noise" of cast iron products are eliminated.
(7) Stable product performance: the high molecular weight material with high molecular weight, stable chemical performance and strong stability is selected as the raw material for the composite trench cover plate. Through scientific formula and advanced technology, the product can maintain stable performance in high and low temperature environment, will not become brittle, and has a longer service life.
(8) Strong corrosion resistance: the stability of the product has been tested by the national chemical building materials testing center. It has obvious acid and alkali resistance and corrosion resistance, and has obvious advantages in practical application.
