quality and advice
What is special about the aluminum substructure of BioMaderas is that the screws sit in two layers of aluminum. This is the prerequisite for using aluminum as a substructure for tropical wood decking boards. Unlike wood, aluminum practically does not weather and since the substructure is machine-made, it also impresses with its straightness when building a terrace. The profile meets the special requirements of tropical wood, so that the substructure is particularly well suited for tropical wood terraces. The aluminum rails are easy to cut and can be used with a plug-in system be extended at will.
If wooden floorboards are installed on an aluminum substructure, the screws between the floorboard and substructure should have a shearing area: wood moves with temperature fluctuations, but aluminum remains rigid - if the screw has no leeway, it will otherwise break quickly. A distance profile, which is placed between the wooden floorboard and the aluminum construction, creates the necessary space. With a concealed screw connection with the BioMaderas-Clips – which are specially adapted to the aluminum substructure – no spacer profile needs to be used.
