The mechanical and quality properties of the preparation of pallet production using spruce wood (Pice abies (L.) Karst.) (with and without knot) and pine wood (Pinus sylvestris L.) (with and without knots) have been assessed. The results suggest that the quality of pine wood was slightly higher - 73.4% of the preparation were of the first quality class and 18.2% were defects. For spruce wood, 67.4% of the preparation were of the first quality class and 12% - defects. Mechanical strength and modulus of elasticity of pine wood (without knots) preparation proved to be slightly higher than those of spruce wood (without knots): on average bending strength was 8.5%, but the modulus of elasticity - 8.3%. Whereas mechanical strength and modulus of elasticity of pine wood (with knots) preparation was slightly lower than those of spruce wood (with knots): bending strength - 4.5% modulus of elasticity - 8.5%. Whereas mechanical strength and modulus of elasticity of pine wood (with knots) preparation was slightly lower than those of spruce wood (with knots): bending strength - 4.5%, modulus of elasticity - 8.5%.
