Bespoke 100% Virgin Plastic Tanks

High Density Polyethylene (HDPE) is used for all fuel tanks. Using the thermoplastic polymer-formed method, we are able to easily cut, fold and weld all tanks inside and out, eliminating the number of joins needed to make a near seamless tank. HDPE is lightweight yet super strong, very low moisture absorption, easily mouldable and resistant to corrosive chemicals and recyclable.

Polypropylene (PP) is used for all types of water tanks. PP is a food grade plastic material which will not taint fresh water and it does not allow odour absorption so ideal for waste/sewage water tanks. Lightweight, super strong and recyclable.

Welding Rod: All our welding rod is made in-house. This enables use of the same HDPE or PP as the tank being manufactured.

Recyclable: All our High Density Polyethylene (HDPE) and Polypropylene (PP) plastic is sourced locally from PRO-FORM in Hamilton (a division of ARB New Zealand).  HDPE is fully recyclable using plastic code 2. PP is fully recyclable using plastic code 5. PRO-FORM practices lean manufacturing. PRO-FORM takes back all processed offcuts to be used into their internal applications.
