Beech wood is one of the most important species used in furniture production in Europe. In this work, the effects of poly(vinyl acetate) (PVAc) bonding [durability classes D1, D2, and D3 according to EN 204 : 2001), finger length (4 and 10 mm), and finger orientation on the bending strength of finger-jointed steamed and unsteamed beech wood (Fagus sylvatica) were studied. Specimens were prepared according to EN 385 (2001) In both steamed and unsteamed wood the specimens with a finger length of 10 mm showed higher MOR than the specimens with a finger length of 4 mm. The MOE of the unsteamed specimens was not affected by finger jointing, whereas, the MOE of the steamed specimens increased slightly (by 5.4%) compared to the control solid wood. It was concluded that it was better to use a 10-mm finger length and the D3 durability class of PVAc adhesives when fingerjointed furniture lumber is produced.
