Rock Plast® FRP Pipes and Fittings offer significantly enhanced mechanical properties, primarily due to the use of continuous glass filament reinforcements, which are wound based on calculated winding angles and advanced technology. Rock Plast® provides a variety of FRP pipe classifications, including Glass Reinforced Polyester (GRP), Glass Reinforced Vinyl Ester (GRE), and GRP Mortar Pipe. These products are available in SN Number 2500-5000-10000 and cover pressure classes ranging from 50 psi to 300 psi in increments of 50 psi. Our Rock Plast® FRP Pipe is meticulously designed by professional engineers to assure the quality of our products and to offer the most optimal cost to our customers. Our FRP Pipe also meets the international standards, such as AWWA M45, AMSE B31.3, and ASTM 2996. Our FRP is fully customizable according to the customer's need based on the size-pressure-stiffness class number (SN). Additionally, the available diameter is available from DN 50 to DN 3000 and the length standard is 6 & 12 meter.
