The most popular size for rafters and floor joists. Made from pine, with a 6-meter length that spans longer distances without joints.
FULL DESCRIPTION The 50×150 mm section is the standard choice for roof rafters and floor joists, offering an excellent balance of strength and manageable weight for easy handling. The 6-meter length allows most spans to be covered without additional joints, reducing connection points and speeding up installation. Thanks to its natural resin content, pine provides good resistance to decay while remaining one of the most cost-effective structural timber options.
APPLICATIONS – Roof rafters (typical spacing: 600–900 mm) – Floor and intermediate joists – Timber-frame wall studs – Terraces, canopies, and pergolas – Formwork ribs and supports
