Resin manhole cover

Fiber reinforced thermosetting composite materials based on unsaturated polyester resin, also known as bulk molding compounds (DMC), are made using compression molding technology and are a new type of environmentally friendly cover plate. The composite manhole cover adopts high-temperature and high-pressure one-time compression molding technology, with high polymerization degree, high density, good impact resistance and tensile strength, and advantages such as wear resistance, corrosion resistance, no rust, and maintenance free.
Product Features:
The resin manhole cover is reinforced with mesh steel bars inside, and the key load-bearing parts are specially strengthened. In the event of inevitable external impact, the pressure can be quickly dispersed to ensure the safety of people and vehicles.
Excluding metal, the steel frame of the stone plastic manhole cover and concrete manhole cover is less than 1/10 of the total weight of the manhole cover. There is not much theft value. Moreover, due to the high strength of the manhole cover, it is difficult to remove this small amount of steel reinforcement from inside the manhole cover.
Characteristics:
1. High strength: It has high compressive, bending, and impact resistance, as well as toughness. After long-term use, this product will not cause the manhole cover to be crushed or damaged, which can prevent the occurrence of "urban black hole" accidents.
2. Appearance Beauty: Exquisite surface pattern design, bright and adjustable colors, beautifying the urban environment.
3. Easy to use and lightweight: The product weighs only about one-third of cast iron, making it easy to transport, install, and repair, greatly reducing labor intensity.
4. No recycling value, naturally anti-theft; According to customer needs and equipped with a locking structure, it can prevent theft of property inside the well.
5. Strong weather resistance: The manhole cover can be used normally in an environment of -50 ℃~+300 ℃ through scientific formula, advanced technology, and perfect technical equipment.
6. Acid and alkali resistance, corrosion resistance, wear resistance, vehicle crushing resistance, long service life.
features:
The resin manhole cover is made of polymer composite materials, with steel bars as the main internal skeleton, and is produced by high-temperature molding. It has high strength and can withstand a weight of 50 tons.
The manhole cover is lightweight, easy to transport and install, and can greatly reduce labor intensity. The new resin manhole cover has excellent anti-theft performance, as synthetic resin materials have no recycling value, effectively preventing the emergence of "urban black holes".
Resin manhole covers have high precision and corrosion resistance. After high-temperature molding production, they have excellent acid and alkali resistance and corrosion resistance, effectively extending the service life of resin manhole covers.
