The aluminum substructure of BioMaderas was specially designed for the properties of BioMaderas-Terrace boards developed from tropical wood. The profile resists stresses that can occur with hardwood decking. It remains warp-free and practically indestructible. The construction rails can be connected to each other with the connection adapters. The rails can easily be shortened with a hacksaw.

Please ensure good ventilation and pre-drill the floorboards and substructure. The swelling and shrinking of wood can cause problems when combined with an aluminum substructure if the terrace is not well ventilated and the wood and aluminum have not been pre-drilled.
