Finger-jointed robinia: decking, cladding and joists
Robinia rarely grows straight over long lengths. To produce long, stable, defect-free boards, we finger-joint the timber: short, narrow boards, known as strips, are cut clear of defects, then joined end to end with finger joints and glued. The result: boards of 2 to 6 m, planed on all four faces.
Our finger-jointed robinia is grade A, kiln-dried to 12% moisture content and bonded with a class C4 adhesive suitable for outdoor use. Density 750 kg/m³, use class 4 (standard EN 335): a service life of up to 30 years, with no chemical treatment.

Joists — the substructure of the deck, in the same timber as the boards.
