There are many ways to attach the tops of the stringers to the structure. One easy way is to screw metal joist hangers to the floor joists or deck supports. Drive screws through the holes in the joist hangers, putting one edge flush with the end of the stringer and the other against the joist. Set the bottoms of the stringers on a firm footing like concrete, wood flooring, or even a block of treated lumber on top of gravel (for outside stairs). Stringers are usually made from 1 in × 6 in (2.5 cm × 15.2 cm) wood. Though you can do without them, screwing these planks vertically between each step will make the stairs look nicer, and last longer.  Cut 1 in × 6 in (2.5 cm × 15.2 cm) boards to the width of your stairs. Secure each stringer with 2.5 in (6.4 cm) screws. Ensure that the riser height is exactly the same for each step. Cut lumber to be at or slightly longer than the tread run in width, and as long as the stairs are wide (or just wider, if you prefer a slight overhang on the ends of your stairs. Secure the treads to the steps of the stringers with 2.5 in (6.4 cm) screws over each stringer.  For instance, you could cut 1 in × 10 in (2.5 cm × 25.4 cm) lumber to the width of the stairs, and use this for your treads. For a special touch, use two boards and leave a 1⁄8–1⁄4 inch (0.32–0.64 cm) between them. For instance, you could cut 1 in × 5 in (2.5 cm × 12.7 cm) boards to the width of the stairs, and install two on each step, with a gap between them. To make extra-strong steps place 2 in × 4 in (5.1 cm × 10.2 cm) boards on both sides of the center stringer under the treads. Trim boards can give your stairs a little more class by covering up the ends of the risers and treads. Cut 2 in × 12 in (5.1 cm × 30.5 cm) boards to the same length and angle as your stringers, but do not cut step notches into them. Place the cut lumber over the ends of your stairs, and fix into place with 2.5 in (6.4 cm) screws. Consider treating the wood against the elements, especially if the stairs will be outdoors. Even if you're...
