As noted on the home page of this site, the operation of our company is done under a Quality Management System certified under ISO 9001:2015 (certificate QMS40629) which covers the design, manufacture, delivery and installation of our tanks.

The design of our products involves not only the expertise of our design consultants Trymak but also subjecting these designs to Finite Element Analysis (FEA) to meet or exceed the requirements of the tank standard AS/NZS 4766:2006.

Materials used by West Coast Poly comply with AS/NZS 4020:2005 which confirms that they are suitable for contact with drinking water and the relevant section of AS/NZS 4766:2006 covering water and chemical storage. These materials exhibit outstanding UV resistance (UV20) and have high thermal stability making them less prone to oxidation, discolouration and loss of toughness.
