The aluminum underconstruction offers complete stability compared to the wooden construction for any conditions. Aluminum profiles are straight and stable in shape. There are no cracks, torsion, swelling and shrinkage - that means any changes in wood due to climatic conditions.
Due to the special shape, the screws are prevented from slipping, and this type of underconstruction allows both invisible and visible connections. The method of connection depends on the type of tree. Some high density exotic woods can only be laid with a visible connection, ie. using screws from above. If you use a grid of aluminum profiles for your terrace, remember to work with screws that are designed specifically for aluminum. We recommend using EUROTEC self-drilling screws.
