The most affordable option (applicable to free draining, relatively dry conditions only) is to use treated softwood. Although softwood substructure will become slimy/moldy easily over time, this is normally acceptable as it is not seen. We can also provide a composite substructure profile which is useful in wet conditions or areas with low air circulation. In particularly damp conditions where the deck is over 1 meter off the ground, we recommend the use of galvanized steel box section beams / hard wood structure or other stronger structure.
