Nowadays, more and more companies are using SMC composite materials to produce manhole covers. Today, PHP will talk about the advantages of SMC manhole covers made by the compression molding process.
1. Lightweight
The weight of SMC manhole cover is only one fourth to one-third of iron cover, so it is convenient to transport, install, and repair.
2. High strength
SMC manhole cover uses high molecular synthetic material with a steel reinforcement framework and is formed by the compression molding process with high temperature and high pressure. The maximum testing result of bearing tonnage is larger than 40 tons.
3. Good anti-theft and self-locking performance
SMC products have low recycle and reuse value, so SMC manhole covers are less likely to be stolen; what’s more, it is self-locking, so the black hole accident in cities can be completely eradicated.
4. Anti-corrosion
SMC materials are natural anti-corrosion, so they have technical and economic advantages for manhole covers used in acidic, alkaline, salty, polluted environments.
5. Good sealing and anti-static property
Oil gas leakage can be effectively avoided to reduce the accident rate.
6. Long service life
SMC manhole cover can be used for more than 30 years.
7. Nice-looking
SMC manhole cover has an exquisite surface pattern with customized company logo, nice and durable.
8. High precision
Since the product is formed by high-temperature compression molding, the joint gap of the cover frame is small. Therefore, the problems of skipping, jumping, and noise that occurs in cast iron or cement manhole covers can be overcome, and the road capacity and drive comfort can be improved.
