Eco-friendly solid composite decking

BiForm is an eco-friendly and durable alternative to traditional hardwood decking. While composite decking has been widely used in other parts of the world for decades, it’s still  relatively new in New Zealand. A 10-year track record of successful hands-on development and testing has seen the BiForm team establish themselves as  leaders in the local market.

Decks Designed for NZ Conditions

Biform composite decking has been formulated especially for New Zealand and Australian high UV conditions. We have backed this up with extensive testing by the Building Research Association of New Zealand (BRANZ) in conjunction with CSIRO in Australia. This testing includes accelerated weathering, UV xenon arc exposure (equivalent of 15 years) and testing of quality control systems throughout the whole supply chain.

BRANZ Appraised

Here at BiForm, our BRANZ Appraisal No. 680 [2015], is something that we are proud of, and being the only BRANZ appraised Composite Decking on the market, it is another thing that sets us apart. After rigorous testing, our decking was given the BRANZ Appraisal. We have held the Appraisal for over 5 years.
