The next step in the construction of the stairs is the purchase of materials — if there is still a desire to build a staircase with the “dumps” between the steps, then the option of buying an iron frame under the staircase itself will be perfect, or its independent structure. To do this, it will be necessary to calculate the width of the steps, the length of the “skeleton” of the stairs, the width of the spans, if any, and measure all this. Then, from a sufficient amount of iron, cook the steps and everything else, build up and attach wooden steps to them.
