Product advantages:
(1) long service life: the company has a perfect quality assurance system to ensure that products meet the ISO9001 quality management system standard, the national standard and the European standard (EN124:1994), the product's anti-aging index reaches more than three grade, and the service life is longer.
(2) High product strength: high quality materials are used 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
(3) Beautiful appearance: the product surface pattern design is exquisite, which plays a good role in beautifying the urban environment.
(4) Light weight: the products made of composite materials have strong toughness and can effectively reduce labor costs in the process of production, handling, installation and use, which is an environmental protection product.
(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 trench cover.
(6) High product precision: the frame 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. 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 and tested by national chemical building materials. It has obvious acid and alkali resistance and corrosion resistance, and has obvious advantages in practical application.
SMC manhole cover
(9) material advantages: the product has strong compression resistance, bending resistance, impact resistance, heat resistance, cold resistance, wear resistance, acid and alkali resistance, aging resistance, and deformation resistance.
Resin composite products are made of polymer composite materials, which are molded by high temperature molding, In the design of composite products, the main factor determining the bearing capacity of manhole covers is the mechanical properties of the product materials. These mechanical properties include tensile strength, compression resistance, bending resistance, shear resistance, impact resistance, etc. the composite products have the characteristics of light weight and high strength, good fatigue resistance, good damage safety, superior molding process, corrosion resistance, beautiful appearance, and strong pattern designability Ideal substitute for manhole cover.
Composite products have been widely used in electric power, mobile communication, gas pipeline, gas station, chemical base, real estate, urban trunk road, high-grade highway, expressway, airport, freight terminal, etc. Products with its unique advantages, gradually integrated into our city life. Due to the strong designability of resin composite materials, the corresponding specifications and shapes can be designed according to the different intentions and requirements of users, and the patterns or colors can be added. Its non recyclable and service life makes the comprehensive cost of maintenance and use of the project reduced to quite low.
After 15 years of innovation and development, the company's products sell well in domestic and foreign markets, and become an influential enterprise in the region. The company always adheres to the business philosophy of "focusing on the safety of well covers and guarding the reunion of thousands of families", and takes "helping customers create value and taking responsibility for the society" as its own responsibility, aiming to create a more competitive made in China.
