Impact of raw material quality versus production of construction elements

For the production of wooden construction determining the quality of pinewood to be used is of vital importance. Material on which the research was carried out came from two quality classes: WBO and WCO. Large-size as well as laboratory samples were obtained from the material to undergo tests of their physical and mechanical parameters. As the result of quality classification process of construction materials the impact of raw material quality on the parameters of semi-finished products used for the production of wooden construction was determined.
