Overview

GRP is highly chemical resistant and suitable for aggressive environments such as acid sulphate soils. GRP is a well-established pipe material that is suitable for the most corrosive of fluids, making it an ideal option for wastewater mains, drainage and waste fluids.

With a fully integrated rubber ring joint, it is especially effective in projects that require large diameters, high pressures, deep burial application, or all three in combination.

We ensure each product is accredited to Australian standards, with our GRP pipe and fittings certified to AS3571.

We offer GRP products that are produced using either the Continuous Filament Winding (CFW) or Centrifugal Casting (CC) manufacturing process.Typically, the CFW process leads to a more material efficient pressure pipe, ideally suited to high pressure applications such as water mains and sewer rising mains.

Alternatively, the CC process produces a pipe that is equipped with qualities for dealing with higher axial compressive loadings, making it an ideal solution for jacking pipe applications. Although they vary in design and application, both methods produce a corrosion resistant pipe with superior strength and outstanding hydraulic properties.
