Laminated veneer lumber (LVL) made from beech wood veneers treated with boric acid by using dipping method was tested for some mechanical properties following different standards. The values for treated LVL varied around the mean values of untreated LVL panels for static bending strength in the grain direction and modulus of elasticity; decreased for compression and splitting strengths, perpendicular to the grain; increased for compression strength parallel to the grain, and for Brinell hardness and pull-out strength of screw, perpendicular to surface.
