Qualitative and Strength Analysis of Pine (Pinus Sylvestris L.) Wood Materials - Study of Pallet Elements

The manufacture of packaging products requires determining the strength requirements of the components that make up the structural elements of pallets, crates and other packaging. Wood, as a renewable material, is the basic raw material for manufacturing wooden pallets. The premise of this research is that the strength of pallets is derived from the characteristics of their subcomponents. Strength tests of lumber were carried out to evaluate the suitability of sawn materials. The measurement of raw material properties assists in the adaptation of individual components to static and dynamic force loads. Pine (Pinus sylvestris L.) lumber was analyzed, taking into account the part of the cross-sectional area from which the wood was taken and the presence of anatomical structure features. The results of the study confirm the influence of cross-sectional location on the strength properties of pine wood and consequently on its suitability for wood packaging. It was found that wood density is not a critical parameter for evaluating the strength of lumber and of the product. Tests of separated types of structural lumber for wood packaging indicate significant differences in the condition of the wood and the magnitude of the strength parameter.
