Remember, you must gather all the right tools and invest in high-quality materials if you want your deck stairs to stand the test of time. Tools and Materials Needed to Build Deck Stairsīuilding deck stairs requires multiple tools and materials. The total rise is a stairway’s overall change in height from the landing pad to the top of the decking. The total run is the overall horizontal distance that the stringer travels. A stair rise is the vertical distance from the top of one tread to the top of the next tread.A stair tread is the width (or depth) of a single stair run.Risers are typically made of fascia board or decking material. Risers are boards installed on the ends to cover the vertical spaces between the treads.It might also be an open stringer with a solid board attached to the side. An “open” stringer has notches that you can see, while a “closed” stringer is a solid board with cleats for the treads. A stringer is a wide board, often a 2x12, that runs at an angle from the landing pad to the deck framing and supports the treads.The stringers must be spaced properly to support the size of the board selected for the treads.

Stair treads may be made of a single 2x12 but typically have two decking boards - usually 2圆s or 1圆s. Stair treads are the horizontal boards that you step on.Building codes in most areas specify that there must be a landing. A landing pad is a flat surface made of concrete, pavers, or gravel at the bottom of the steps.Before you start building, you must first learn the parts of deck stairs.
