The invention relates to a tower for a wind power plant having a plurality of corner bars (1) for forming a mast construction, wherein the corner bars (1) are each made up of a plurality of partial profiles (2) connected to each other and having opposing connection areas (3a, 3b) at which the adjacent partial profiles (2) of a corner bar (1) can be connected to each other, and wherein the partial profiles (2) each have two kink points in cross section extending in the longitudinal direction of the partial profiles (2) in a segment located between opposite connection areas (3a, 3b) of the partial profile. The corner bars (1) are each formed of at least three partial profiles (2), wherein the at least three partial profiles (2) of a corner bar (1) form a closed overall profile having an annular cross section, and that the joints at the connection of connection areas (3a, 3b) of adjacent partial profiles (2) of a corner bar (1) are each flush with an adjacent joint of an adjacent corner bar (1) extending the corner bar (1) in the longitudinal direction.
