Solid structural timber is a material that is specifically developed for the high requirements modern wood construction. It is a technically dried, strength-graded and finger-jointed solid softwood timber product. The production process starts with drying of spruce timber to a moisture content (15% +/-3%). The wood defects such as large knots or wane, labeled and excluded. Sorting is done first in order to achieve a certain level of strength. At the ends of the different length of the segments of slats finger joint profile, and then lamellas are glued to each other under pressure. After curing of the adhesive a ready-made timber planed on all four sides.
