Set of step elements for angular winding staircase, particularly for staircases with an external right angle. Two step elements (11, 11') have different long sides, where the short side (18) of the one corresponds to the long side (17) of the other. Each step element (11) comprises two main sections (11A, 11B) which are joined around a centrally placed axis (13). In each main section lamellas extend at an angle which is equal or similar to 1/8 of a right angle in relation to the axis. The narrow end side (14) of the step elements form a right angle to the axis. |
