Dark Grey Dual Colour  Decking Board For Outdoor Flooring Project

Composite Warehouse are proud to offer our timeless anthracite grey decking board, rated by our customers as the best choice in all aspects of overall performance. This collection offers fade, stain, mould and mildew resistance. It also requires minimal maintenance compared to our essential collection. Our Timeless board has been engineered to stand the test of time hence the name timeless. 

Our Timeless collection is a capped dual colour composite decking board. Dual colour is two colours in one singular board. These two colours are grey and dark grey also referred to as anthracite grey, supplying customers the choice to flip the board over in time or use the growing trend of a contract picture frame finish.


Capped composite decking boards can also be referred to as second-generation composite decking. The board is produced with a hard-wearing shell and a thin plastic layer to help protect against UV rays and stains, enabling low maintenance. This means by opting to purchase our timeless collection, you will benefit from increased colour stability as it protects against family spills of wine, beer, fizzy drinks and even BBQ spills of grease, ketchup and much more.


How do our boards perform with slip resistance? Our timeless collection is one of our best-performing boards for slip resistance, passing EN-15534  test reports. Hazard decking areas are now a thing of the past when you choose composite decking.

Another key feature of our timeless collection is that it has extremely low water absorption; this prevents a breeding ground for mould and mildew, ensuring they are kept at bay. 

Our timeless collection comes with a 25-year residential warranty supplying customers with the piece of mind about the future performance of our product. 


Here are the reasons our customers love this composite decking board.

  • Our Dark Grey Composite Board comes with a 25 years warranty*.
  • Timeless Dark Grey Decking Board has an Ultra-violet, stain, and slip-resistant surface* that ensures your deck stays as good as new for many years.
  • It is lightweight and easy to carry.
  •  An easy-to-maintain board with a capped surface that protects it against mother nature elements & keeps a stable colour for decades.
  • Complete ultra-low maintenance compared to its wood cousin and first-generation wood fibre boards.
