A manhole cover or maintenance hole 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 maintenance and other work on an underground utility vault or pipe. It is designed to prevent anyone or anything from falling in, and to keep out unauthorised persons and material.

  • All BRIGHT GREAT Covers are self pigmented and hence, doesnot require painting. However, if wanted they can be painted.
  • All BRIGHT GREAT products are UV stabilised and hence, there is no effect of sunlight.
  • Due to poor heat transfer properties of FRP, FRP Covers do not absorb heat and remains at normal temperature under sunlight. Hence, it is convenient to handle BRIGHT GREAT FRP Manhole Covers under extreme hot conditions.
  • As the FRP Manhole Covers are flexible and do not disintegrate into pieces due to excess load bearing imparted on the cover, accidents on roads are avoided as the chambers are not left open even in case of cracking of cover.
