Abstract

This research evaluated the quality of Eucalyptus dunnii sawn wood for use in the lumber industry. Logs of 25 and 30 cm of diameter were used, broken down according to two methods. The first method produced boards with tangential faces and the other method produced boards with radial faces. Defects such as crooking, bowling, cupping, and index of cracks in boards, in two humidity conditions, were appraised. Defects were appraised before and after drying, i.e. after reaching the humidity balance. The crooking was more intense in radial boards. The bowling was similar in the two studied systems. Cupping only happened in tangential boards after drying. Cracks were more intense in tangential break down, presenting larger evolution after drying, when compared with radial break down. The breaking down system envisaging boards with radial faces presented pieces of better conditions for industrial purposes.
