West Coast Poly tanks are manufactured to cope with the harsh West Australian environment and are suitable for external installation. West Coast Poly uses a material which has a UV performance level of UV 20 which is more than the Australian standard requirement. This material is standard for our storage tank range so that customers can be assured they are getting the highest UV protection available.

LMDPE – a hexene grade co-polymer based linear medium density polyethylene. The material offers excellent impact strength and long-term UV stabilisation it is suitable for manufacturing a wide range of products.

HDPE – A new generation of Hexene HDPE, principally for chemical storage tank applications. Suited for manufacturing large storage tanks, the advanced technology of the material leads to superior mechanical properties, high impact strength, high stiffness and long-term UV stabilisation.

Our tanks are a seamless single piece construction making them tough, durable & long lasting in even the harshest condition. We achieve this by using state-of-the-art machines and techniques at our manufacturing facility in Canning Vale WA. Cutting edge computer systems enable us to monitor the internal temperature, rotations and cook times. Ensuring each tank produced is of the highest quality. You can learn more about our manufacturing process here.

Our quality assurance team conducts rigorous and thorough testing on each tank, making sure every tank meets our precise quality specification. Through means of impact testing, ultrasound testing and hydrostatic temperature.

Impact Testing: To ensure the performance & workmanship of each finished tank, a member of our quality assurance team cut samples from a tank after it is made and freezes them. Once the samples have reached -40c we use a drop dart to evaluate impact strength & toughness, ensuring the vessel meets our quality standards.

Ultrasonic Testing: To ensure an even and thick tank structure, our quality assurance team use precise ultrasound equipment, anywhere on the tank walls, roof or floor. This specialised technique allows us to measure the thickness profile of the tank & make sure it’s the exact thickness to meet our quality specification & standards.

Hydrostatic Load Testing: If the tanks have specialised fittings, our quality assurance team can conduct pressure and leak testing, ensuring your tank is fit for purpose when it arrives at site.

Lifting Load Point Test: Testing conducted to achieve certification on the tank lifting points to the working load limit.

In keeping with the high-quality standards applied to manufacturing, West Coast Poly keeps meticulous records of their manufactured products. Standard details of all tanks are recorded with the tanks unique identification number.
