The same SMC composite manhole cover, what's the difference?_

Because of different processing technology, structure and materials, the performance of the composite manhole covers is different.

Generally, composite manhole covers adopt layered composite method. Different reinforcement materials are used at different parts of the covers. BETTER COVER ‘s covers:

High temperature film pressing processing technology: independently designed and developed mold, one-time high temperature molding using SMC materials. BETTER COVER optimizes and upgrades materials independently on the basis of the original SMC materials. Through the perfect material ratio, the manhole cover is technically lightweight, and the bearing capacity, deformation resistance and fatigue resistance of the manhole cover are greatly improved. Meet or even exceed industry standards.

Some manhole cover manufacturers can only use the thick bottom design to increase the bearing capacity by increasing the thickness of the well cover because they can't master the best formula ratio of materials. Such well covers are generally heavy, which will increase the labor cost for later installation, maintenance and servicing.
