What are the advantages of cast iron manhole covers? It is a special product designed to prevent people from falling down after they dig sewers. The manhole cover is widely used in people's life. Its material and technology are one of the factors that determine the quality and safety. It is not only safe in use, but also has anti-theft function. What other advantages does it have?

1. Sound prevention: the contact surface between the nodular cast iron well cover and the well ring is machined to make it more consistent without abnormal sound.

2. Anti slip: diamond block pattern is cast on the surface of the well cover, the inspection well ring uses the structure of ring to ring connection, and T-shaped bulges are set on the surface of the ring mouth to increase the friction coefficient, so as to increase the friction coefficient of the asphalt base material behind the auxiliary road and the ring mouth.

3. Displacement prevention: because the well ring of the nodular cast iron well cover is fixed with the ground by anchor bolts (small round holes play a role in fixing), the inspection well cover will not be staggered due to the rolling of the road roller during construction, so as to meet the standard construction.

4. Fall prevention: the new five prevention manhole cover has a built-in fall prevention grid to prevent people or other objects from falling due to the loss of the manhole cover, causing injury.

5. Anti theft: The nodular cast iron manhole cover is equipped with an anti-theft cassette and a folding plate under the well ring to replace the anti-theft chain, which completely plays the anti-theft role and fundamentally eliminates the rust problem caused by cavitation and water erosion.

When designing the ductile iron manhole cover, we need to consider many things. We should not only ensure the quality of the product, but also ensure that it can be more safe in application. Therefore, in application, we are more popular with users. The reason why each product is popular is determined by user satisfaction.
