No matter what you want to put the finishing touches to a new deck or replace an existing staircase, build outdoor stair treads is as easy as following the method used by carpenters to design and cut stairs with equitable measures, firm structures and of any length. With the basics of geometry, common tools and materials, building wooden stairs is something that can be accomplished. Supports the end of the topographic level on the surface of the deck so that it extends above the ground. Then use a tape measure to measure the vertical distance between the bottom edge of the topographic level and terrain. This will let you know the total lifting of the stairs.
Calculate the number of steps that need dividing the measure of the total lifting of seven. If the calculation does not yield an exact number of steps, rounded up to the next number. To determine the height of each step, known as a riser or riser, the site recommends outdoor stair treads that you divide the total rise of the staircase by the amount of steps. For example, if the total rise is 32 inches (81.28 cm) and divides by seven, the result is 4.57. To round this number up to five means they are five steps.
