If you add a new staircase, you must determine the length of the railing. Measure the space between the outer edges of the stairs to the support pole running through the middle of the metal spiral staircase, which is the radius. You also need to measure the distance from the bottom of the first floor to the bottom of the second floor, which gives you the height of the stairs. Multiply the radius of stairs from Pi and 2 and the square figure. Square the height of the steps and add it to the last poll. Find the square of the final number, which gives the length of the stairs.
Metal spiral staircase adds a dramatic look to any home. Designers and architects normally set the staircase in the middle of the room or slightly off-center. The staircase winds around in a circular pattern to the second floor. The edge length of the steps is variable and depends on the total length of the staircase itself.
