The air in coastal cities is humid, and traditional manhole covers are prone to corrosion and rusting. By selecting products suitable for the local conditions, the government can reduce the risk of manhole cover corrosion and damage, ensuring long-term use and safety.

The manhole covers used at gas stations need to have excellent physical and chemical properties to adapt to the special environment of a gas station and ensure safety. SMC material manhole covers are the best and most widely chosen option for gas stations.

Combining features such as environmental friendliness, lightweight, and smart manufacturing, the future development trends of SMC products and SMC manhole covers remain positive, aligning with the requirements of sustainable development.

With the continuous advancement of material science and molding technology, SMC (Sheet Molding Compound) has emerged as a high-performance composite material that is gradually replacing traditional materials such as plastics, steel and aluminum in various fields, including construction, automotive, and aerospace.
