GRP PIPE (Glass Fiber Reinforced plastic pipe) 

Glass Fiber Reinforced Plastic pipe (GRP pipe) is based on unsaturated polyester resin and comprises sand to enhance stiffness and continuous glass fiber to improve performance against internal pressure, GRP pipe is characterized by superior leak tightness against subsoil variations caused due to earthquake or settlement of poor land, superior stiffness against high earth pressure, superior elastic safety against instant weight variation due to vehicle loads etc. and superior corrosion-resistance against salt, sulfuric gas.etc.
