Fiberglass square manhole cover is made of resin, surfacing mat and fiberglass can be widely used in the street.
Unlike the bulky, awkward cast iron manhole covers of the past, precast concrete and fiberglass manhole covers are lightweight and easy to handle and transport. Unlike iron covers, this fiberglass cover has little interference with radio frequency signals used by remote monitoring and remote data retrieval systems. The device is non-conductive and non-corrosive, making it ideal for use in the harshest environments. UV stable, the surface will not peel or crack, and has a maintenance-free lifespan of at least 30 years.
Applications include petrochemical, water and wastewater, natural gas, power, communications and municipal use. The lockable drain cover locks the cover and frame together and provides a seal between the two layers, making the installation odor-proof. The range offers lockable lids and hinged designs for easy access to any manhole.
