FRP manhole covers (Fiberglass Reinforced Plastic) are a type of composite manhole cover that is made of polyesters and fiber glass. This lightweight manhole cover is exceptional when it comes to durability, strength, and corrosion resistance. You must ditch the traditional manhole covers.

A manhole cover is a removable plate forming the lid over the opening of a manhole, an opening large enough for a person to pass through that is used as an access point for an underground vault or pipe. It is designed to prevent anyone or anything from falling in, and to keep out unauthorized persons and material.
