Complete Your Outdoor Staircase With Deck Stair Risers


A beautiful set of deck stairs can enhance the overall look of your space while providing convenient access between your yard and deck. Deck stair risers are an important finishing touch. By enclosing the space between your exterior stair treads, they give your staircase a complete look while complementing your overall deck design. Look to Lowe’s to find the deck stair risers and outdoor stair treads to complete your project.


We offer pre-finished composite stair risers that coordinate with our supply of decking boards. Choose from a variety of colors and natural hardwood grain patterns. These boards are wrapped in protective layers to prevent staining and fading, and they clean easily with soap and water. The composite core resists splintering, insect damage and decay.


Our outdoor step treads include unfinished or stained pressure-treated pine with slip-resistant grooves for safe stepping. To ensure the longevity of your tread, look for wood treatment that meets American Wood Protection Association (AWPA) standards.
