All of products are picked, checked and packed for delivery making sure everything meets our high standards.
Build Grandmaster to your specification

Choose from base-coated or pressure treated finsh which comes with a 15 year anti-rot guarantee*. Upgrades from external cladding thickness (11mm or 16mm) to flooring thickness (11mm, 19mm or 28mm) providing a stonger base for heavier applications.
