A support for steps, having the shape of a triangular corner plate to be installed one after the other along a stringer. The sides of this support ar e reinforced, horizontally and vertically by a 90 degree fold, to fix the step s and risers. The ends are wider and possess a number of fixing holes to provi de more stability when fixed against a stringer. The horizontal side is ended b y a projecting horizontal rule. The wide part of the vertical side is flanked by vertical graduations. The horizontal rule is set against a stringer at a desired step run and the vertical graduations are set against the stringer a t a desired step rise. The horizontal rule is at least the thickness of the plate away from the stringer and it overlaps the vertical graduations of the preceding support, thereby preventing warping of the plate when overlapping.
