Modern and contemporary exterior spiral stairs are a great way to add an architectural detail to the backyard, deck, or patio. At Acadia Stairs, our exterior spiral staircases are high-end, versatile, and durable. They can fit in virtually any space and in any environment.
Our goal with every staircase is simple: get you from point A to point B safely and in style. With added strength and durability, our exterior spiral staircase designs will add dimension and functionality to your patio, deck or balcony. We’ve worked on a variety of outdoor projects across New York City and Connecticut. Check out some of our past work and let us know what you think!
Exterior stairs should be both visually pleasing and extremely durable, and our custom stairs are the perfect blend of the two.

Outdoor Spiral Staircase Installation
Below you’ll see the installation process of one of our outdoor projects! This is an all aluminum spiral staircase that we fabricated and powder coated white in our shop, then shipped out to be installed at its new home. This particular staircase features a railing with vertical lines, but we are able to design your stair with horizontal lines or a mesh-style rail to match your style. We make the spiral rail in a heavy-duty kit system that makes the stair easy to install and very durable over time.
Here, the main balusters are in place—one baluster per step is all that’s required to hold the handrail up and provide strength at the outer perimeter of the treads. The handrail is a 1.5″ diameter rigid aluminum tube. The balusters have a special tab on top that is pre-drilled and coped for the round handrail while the bottoms are pre-drilled for tread-to-tread connection.
Here’s a closer look at the staircase with the middle balusters in place. The middle balusters complete the look of the staircase and reduce the spacing to less than 4″ as is required for most codes. Diamond plate treads provide an anti-skid surface even when it is wet outside and the stainless steel hardware is painted in our shop to match the finished stair color for a more cohesive look.
The final look: the top of the staircase has a special railing called a closure rail that is welded to a sleeve that slides over the center pole. The center pole is hidden inside of the precision-cut tread sleeves, platform sleeves and closure rail sleeve, providing both a clean look, and weather resistance. The top platform is built to receive decking, but you can choose to match your platform cover to your treads.
