ABSTRACT A wooden pole or standard for power lines or the like comprises a number of staves having trapezoidal cross-section with side faces forming a mutual angle of 360/n degrees, n being the number of staves in the pole, and which staves are glued together along adjacent side faces so that a pole having a centrally extending hollow space is formed. All staves are equally shaped lamellae in a number which, for the cross-sectional dimension in question, is sufficiently large to achieve a laminated structure in the circumferential direction of the pole, and the individual lamellae are, as required, finger- jointed for achieving the desired pole length.
