Acadia Stairs specializes in designing modern and contemporary staircases for the home. However, as evidenced by many of our straight stair designs, we are able to deftly blend tradition and innovation.

Stringer stairs, which offer support for the treads, are renowned for being precise, durable and strong. The most popular option among our straight stairs is the single stringer stairs, which are sometimes referred to as mono or center stringer stairs. These stairs provide both a modern and elegant look. However, our double and pan-type stair options are also popular among clients searching for a specific look and increased durability. The double stringers are also a more economical option for our customers.

Our modern and contemporary straight stairs are open risers that you can see through; however, we can also close them if that is what the client desires.

We will fabricate your custom metal stairs to your specifications, as we make them precisely to shop drawings. Additionally, we will ship our stairs to any place in the country. If you have any questions, or if you would like to learn more about the many options we offer, please contact us today.

Acadia Stairs designs and fabricates stairs with steel or stainless steel stringers. The stringer, or stringers are the support for the treads. In having a steel stringer, the stair is very precise, durable and strong. These stairs can be made to have a much more open look than a typical wood box stair.

Most of the stairs we sell are open riser stairs that you can see through, but we also make closed riser stairs.

The stringer(s) can be made from:

  • A single stringer down the center of the stair
  • Double Stringers going down under the treads, set in from the edges
  • Pan-Stair (Outer Stringer) where stringers are at the perimeter of the treads

These stairs can be made in almost any configuration:

  • Straight-line
  • L-shaped
  • U-shaped (aka switchback stair or scissor stair)
  • Geometric winder treads
  • & combined with curved stairs or spiral stairs!
