Mechanically laminated timber (MLT) is an engineered wood product that is intended for structural applications subjected to out-of-plane loading. The MLT layups contain lumber laminations connected to parallel to each other along adjacent laminations on the wide face using either steel metal or wooden fasteners, with the laminations loaded on edge. The fibre directions of all laminations within MLT are parallel to each other. In this standard design specifications for MLT products produced in accordance with a parallel proposed product standard are provided.
