The straight stairs comprise a maximum of four structural components consisting of two support beams (1), between which step profiles (2) are fixed by means of fixture components (18) inserted through the beams, gripping into tracks (14) in the profiles. The beams can be joined with plates of length greater than the basic dimension of the modules. The support strength of the beams can be increased by the addition of a freely selectable number of joint and reinforcement plates. The step profiles can be extended by step joint plates to greater lengths than the basic dimension of the modules. The step profiles and beams can be provided with insertable decorative and/or wear material (11). |
