Resin manhole cover is a manhole cover made mainly of unsaturated polyester resin and other polymer composite materials, with the addition of reinforcement materials, fillers, etc., and compounded through certain processes. The following is a detailed introduction and purpose:

Product Features

●Strong anti-theft performance: It is made of unsaturated resin, fiberglass and other materials, as well as steel reinforcement skeleton, which are compounded by special production processes. The materials have no recycling value, and it is difficult and costly to remove the steel reinforcement, with active anti-theft function.

●High load-bearing capacity: The bottom adopts a special pot bottom structure, which increases the load-bearing area. At the same time, continuous reinforced fiber filaments are used to ensure that the product has sufficient load-bearing capacity, which can meet or exceed national standards.

●Long service life: By using high-performance resins, glass fibers, and special production process formulas, the penetration of resins into glass fibers is ensured, enhancing their adhesion and preventing internal damage under cyclic loading. The service life can reach more than 20 years.

●Beautiful and practical: According to customer needs, complex logos and personalized designs with multiple colors can be made on the same manhole cover surface. It can also be made into imitation stone surfaces and colors to beautify the urban environment.

●Superior performance: It has the characteristics of high temperature resistance, low temperature resistance, good insulation performance, strong corrosion resistance, etc. It can be used normally in the environment of -50 ℃ -+300 ℃. After testing, many indicators such as acid and alkali resistance, anti-aging, etc. have reached and exceeded the national standards.

●Environmental protection and anti slip: After being crushed, the car does not slip, there is no harsh noise or rebound phenomenon, and the product is lightweight with precise closure of the cover and seat, overcoming problems such as "jumping, tilting, noise, and displacement" of other inspection manhole covers.

Product Usage

●Municipal engineering: widely used in urban drainage systems, sewers, rainwater wells and other places. Its anti-theft, lightweight, corrosion-resistant and other characteristics can ensure the normal operation of urban infrastructure.

●Road traffic: Suitable for busy areas such as urban roads and highways, it can withstand the long-term pressure of heavy vehicles, and the lighter weight reduces the time and cost of traffic construction.

●Underground pipelines and power systems: commonly used in power wells, communication wells, gas wells, etc., their corrosion resistance and pressure resistance can protect important facilities such as underground pipelines and power cables.
