Laminated Veneer Lumber
LVL (Laminated Veneer Lumber) is an engineered wood product created by edge-joining veneers of standard dimensions and bonding them in layers with parallel grain orientation. We offer standard sizes ranging from 25 to 210mm in thickness, 25 to 600mm in width, and 1800 to 6100mm in length. Our product line includes finishing-grade materials predominantly made from Japanese cedar (Sugi), as well as structural components manufactured from various softwood species including Japanese larch (Karamatsu), Japanese red pine (Akamatsu), and Douglas fir—all selected to meet specific strength categories in accordance with JAS standards.
