MOSO® Bamboo N-durance® sub frame joists are made of the same material as MOSO® Bamboo N-durance® decking boards: Outdoor-Density® bamboo, made from compressed bamboo strips.
We recommend the use of Bamboo N-durance® sub frame joists, which are specifically produced for use in combination with MOSO® N-durance® decking, to optimise the longevity and performance of your deck.
