FRP Manhole Cover also called GRP manhole cover, mainly divided into SMC( Sheet Molding Compound) and BMC( bulk molding compounds) covers according to material difference. They are both fiber reinforced plastic manhole covers.
FRP(Fiber reinforced plastic) is newly developed material of manhole covers. Before FRP came into existence, manhole cover were traditionally manufactured from concrete, frp, cast iron, ductile iron or PVC material, but these materials had their own shortcomings like low load carrying efficiency. FRP is considered to be the best alternate material for manhole covers as it has longer lifespan and has the capacity to withstand heavy loads. Increase in heavy traffic and expensive metals completely replaced traditional covers with FRP manhole covers.
