Custom Double Stringer Stairs

The double stringer stair is an affordable option for homeowners looking for custom staircases. With a variety of materials and styles available, Acadia Stairs can match your new double stringer to virtually any design.

Double stringer stairs use two support members for their structure down under the treads and in from the edges of the stair for a floating look. The carriers for the treads are usually angle irons, flanged in toward the middle of the stair for a cleaner look from the side. Double stringers can be used in residential or commercial applications, as well as in both interior and exterior projects.

You’ll find extra support without all the bulk of a traditional staircase, allowing you to keep your space open and bright.
