Product advantages

1. Light weight, the weight of FRP manhole cover is only 1/4-1/3 of that of iron cover, which is convenient for transportation, installation and emergency repair.

2. High strength, made of polymer synthetic materials, equipped with steel skeleton, molded by high temperature and high pressure, the highest test result is more than 40 tons.

3. Anti-theft, good self-locking. FRP products have low recycling value, and using them as manhole covers can avoid the hidden danger of being stolen and sold as scrap; in addition, the unique constraint connection structure of FRP circular manhole cover and manhole seat can prevent theft of manhole cover and cause traffic accidents such as people and cars falling into or getting stuck in the well, which can completely prevent the occurrence of "urban black hole" accidents.

4. Corrosion resistance, FRP material is naturally corrosion-resistant, and it has technical and economic competitive advantages when used as manhole covers in corrosive media environments such as acid, alkali, salt, and sewage.

5. Excellent sealing performance and anti-static function can effectively prevent oil and gas leakage and reduce the accident rate.

6. Long service life, with a service life of more than 30 years.

7. Beautiful appearance: The surface pattern of the fiberglass manhole cover is exquisitely designed and can carry the company logo, which is both beautiful and durable.

8. High precision: Since the product is molded by high-temperature die-casting, the gap between the cover and the seat is small, which overcomes the problems of cast iron and cement manhole covers such as "running, jumping, and making noises", and improves the road traffic capacity and driving comfort.
