Substructure Angelim Pedra finger-jointed | four sided smooth | FSC®100%

Angelim Pedra comes from Central or South America. It is a very hard wood and is ideally suited for outdoor use thanks to its good resistance (durability class 2) and its technical properties. The wood is 100% FSC certified and comes from legal logging. The substructure is untreated, finger-jointed or solid (not glued) and planed on 4 sides.

Grading

The substructures (UK) are generally available in a standard quality. Occasionally, sub-constructions with damage, cracks, areas that have not been planed out cleanly and drop-out knots may occur. The goods are not re-sorted and therefore contain all grades from A to C. In some cases, the individual substructure battens cannot be used in their full length and must be cut to a healthy length on site. We recommend that you plan for at least 10% of the goods as a reserve or offcut.

Assembly

The installation must be carried out professionally, i.e. the maximum distance of the substructure must not exceed approx. 40-45 cm. A slope of at least 2% must be maintained in the longitudinal direction of the boards. The decking boards must be well ventilated. Waterlogging must be prevented by structural wood protection such as rubber or plastic underlays. Please use only fastening materials made of stainless steel (V2A or V4A) for installation. Simple fastening materials that are only galvanised react with the ingredients of the wood and lead to unsightly, usually dark discolouration. If the screws are visible, the holes must be pre-drilled to avoid cracks and splintering due to the tension in the wood. Treat the decking boards with an end-grain wood preservative at the ends to prevent drying-related cracks at the board ends.
