Abstract
A step for modular staircases, preferably produced by molding using a thermoplastic technopolymer, comprises at least a main body (11) and a spacer (12). The main body (11) comprises at least a tread surface (Ha) and a hollow portion (lib) extending vertically with an internal thread (111), while the spacer (12) has an external thread (121) matching that of the hollow portion (lib) of the main body (11), allowing the spacer (12) and the hollow portion (lib) to be screwed together. The hollow portion (lib) and the spacer (12) also have ends (112,122) which do not interact, shaped to match one another, to allow vertical stacking of two or more steps (10), thus obtaining a modular staircase (1), complete with a landing (20) produced in a similar way to the step (10).
