The Difference Between Composite Manhole Cover, Cement Manhole Cover and Cast Iron Manhole Cover
The manhole covers are mainly divided into three categories, namely cement manhole covers, Composite Manhole Covers, and cast iron manhole covers. What is different between them?
1. Appearance: The composite manhole cover series products are smooth and beautiful. Coloring and designing patterns according to design requirements;
Cast iron manhole cover series products are easy to rust, corroded, and the appearance is not good;
The surface of the cement manhole cover series is uneven, the coloring is difficult, the product is brittle, and it is easy to fall off the corner.
2. Weight: The composite manhole cover series is light in weight, about one-third of the similar products of cast iron and cement.
3. Toughness: The composite manhole cover series has good toughness and is not easy to be brittle;
The cast iron manhole cover series products are rigid, lack of toughness and easy to be brittle;
The cement mandrel series products are strong in solidity, lack of toughness and rigidity, and are easily brittle.
4. Exercising of the vehicle: The composite manhole cover series product covers are tightly combined, and the balance is not warped or bounced;
The cover of the cast iron manhole cover series is not tightly coupled, and the vehicle is easy to bounce when driving, and the noise is large;
The cover of the cement manhole cover series is not tightly coupled, and the vehicle is easy to bounce when driving, which is easy to damage.

5. Maintenance: The composite manhole cover series products are characterized by corrosion resistance, light weight, coloring, good airtightness, etc., which are easy to identify and open and maintain daily, which effectively reduces the labor cost of maintenance and the expenses of renewal expenses;
The cast iron manhole cover series products are heavy, easy to rust and corrode, easy to lose, and increase maintenance difficulty and update costs;
The cement manhole cover series products are heavier, and the products are not enough to increase the maintenance difficulty.
6. Unit cost: The unit cost of composite manhole cover series products is lower than 40% of cast iron manhole cover series products, 20% higher than cement manhole cover series products.
