Exterior spiral staircase-The tread staircase is the horizontal part of each stair build. It is the part that you are actually going to step on when you go up and down the stairs. The piece that connects the steps called stair riser. A do-it-yourself project for those experienced with similar projects is building exterior spiral staircase, which is likely part of the measures leading to a deck or porch outside. When the sides and base pieces of the staircase are built, the next step will be to install the external stairs.
Measure the pattern size of the stairs. This is the total depth of the steps that you install less one-half inch of overhang. Calculate the height of each tribe. First, measure the height of the total exterior spiral staircase. Then share it with the number of risers you plan to install. For example, if the total height is 28.5 inches and you want four risers, each tribe will be 7 1/8 inches tall.
Cut lengths of wood treads and risers using the measurement you took. Use a circular saw to make cuts. Place the tribes against the stair sides and base pieces in between the pages. They will be pushed into place vertically to cover the back of each staircase. Attach with a drill. Set the steps in place in front of the risers installed. Use your drill to attach the treads to the stair sides and base pieces.aluminum spiral staircase, aluminum spiral staircase prices, installing spiral staircase, exterior spiral staircase, spiral staircase exterior
