The innovative ACO Manhole Cover System has been developed to meet today's urban infrastructure challenges. The intelligent structure of the elements allows the distribution of dynamic traffic load to ensure that the cover remains at the level of the road surface. The flat surface of the installation guarantees safety and comfort when passing.

The material is Sheet molding compound (SMC) resin, a fiberglass-based compression molding that is used in applications that require high strength. SMC is comprised of several materials including fiberglass, polymer resin, release agents and thickeners.
