COEN. The Green Alternative.

  • Made from 90% recycled materials, offering superior ecological sustainability to timber.

  • Certified non-toxic and safe, COEN Composite Wood contains NO ASBESTOS or FORMALDEHYDE.

  • Any excess from manufacturing and construction waste is recyclable.

  • It is resistant to termites, water & fire.

  • No need for chemical based treatment ie. no oiling, staining or painting.

  • Energy efficiency benefits to lower long term costs and reduce carbon footprint.

  • Our manufacturing facilities have ISO9001/14001 and also hold ATSM and CE certification for our products.


Composite Wood provides significant environmental, time and cost savings when compared to natural timber products.

We took a Merbau Hardwood 90mm timber product and compared the total cost over 5 years to COEN Composite 140mm boards on a 20 Sqm deck*. The total cost savings of a COEN Composite deck versus a Merbau deck over 5 years is between $1,400 to $2,000 on a 20sqm area.

*Estimated $50 cost per year for COEN maintenance versus $300 cost per year for Merbau Hardwood. Annual costs considered are time, varnish, brushes/rollers and cleaning agent.
