I have 13.7sm of Hyperion Frontier composite decking made by Envirobuild for sale. This 13.7sm consists of 24 full length 4m x 143mm x 22mm boards that were leftover from my deck build. I also have a few offcuts that are not included in the square meterage. I will also include several all of my leftover fixings which include the secret fasteners as well as some decking screws used to secure the outer boards, if you desire. Price for boards alone direct from envirobuild is £1K. First photo in listing is the my deck made with these boards.
