FRP/GRP Composite manhole covers main components are fibreglass and unsaturated resin. Our factory existing moulds load capacity are A15, B125, C250, D400, E600 etc. We can free design, Such as Color, Logo, Panel, Load and Dimension. We can be designed according to the requirements of customer. The covers non-conductive and non-sparking, has no value of recycling, completely solving the theft problems .The minimum lifespan is 30 years free of maintenance . It can be installed hermetically, and effectively prevent poisonous gases leaking out from cesspool. It will not rust because it has good wear and corrosion resistance.High and low temperature resistance, excellent insulator ( from-40°C~200°C), the weight of composite manhole cover especially SMC manhole cover is lighter more convenient to transport, install and repair.
FRP manhole cover is Fiberglass reinforced plastic covers, It adopts unsaturated polyester resin as matrix of fiber reinforced thermosetting composite material, also called regiment shape mould plastic , with pressure molding technology is made, is a kind of new environment-friendly power cover plate.
With high-temperature and high-pressure once moulding technology, the degree of polymerization, high density, long service life, have wear-resisting, corrosion resistant, non-rusty, non-pollution, free maintenance etc.
