Where can square composite manhole covers be used? In the urban trunk road, generally use circular, from the mechanical point of view, the mass of the composite well cover is circular force uniform, when driving vehicles and driving through when not easy to tilt, can better protect the safety of pedestrians and vehicles.
Where can square composite manhole covers be used? In the green belt and small non-motorized lane driving area, the general use of square, simple construction, strong adaptability, so that we can better use the square manhole cover to bring convenience.
What are the product features of the new resin composite manhole for high temperature and corrosion resistance
1. light weight, gas station lane manhole cover weight is only 1/4 of the iron cover, engineering installation and use of light and flexible opening and closing.
2. self-locking is good, it has the function of self-locking to prevent the car from jumping off the seat of the rear manhole cover.
The 3. strength is high, the tensile strength of FRP material is equal to that of Q235 steel, and the compressive strength is more than twice that of C30X, and the impact resistance, vibration, fatigue and fracture performance are superior to those of steel and iron, which are used as well covers for bearing
4. prevent theft, FRP products have no recycling value of waste products, used as well cover can avoid steel manhole cover often stolen as waste sale hidden danger, thus prevent the manhole cover theft caused by people, cars fall into or stuck in the well traffic accidents, reduce the owner's economic losses and accident liability.
5. corrosion resistance, FRP material natural corrosion resistance, used as acid, alkali, salt, sewage and other corrosion medium environment manhole cover, with technical and economic competitive advantage.
