Abstract (en)
An improved step for treadable-grating staircases, of the type comprising a grating stair tread (1) having a length suitable for the width of the staircase, as well as at least two end plates (5) for attachment of the step to the outer stringers of the staircase, welded on which are the bars of the grating. To obtain a functional and structural co-operation between said stair tread (1) and reinforcement elements that are provided underneath the treading surface of the step itself, in the bottom part of the stair tread (1) an obscuring panel with inclined bars (2') is integrated to implement an anti-vertigo function, which inclined bars (2') are rendered fixed to the end plates (5), as well as structurally participating by means of one or more bands (3) made of sheet metal arranged orthogonal thereto and to the treading surface.
