Curved Side Stringers

Versatile yet stylish, the curved side stringer staircase can be freestanding or attached to a wall, making it a popular option for homes and businesses. Curved side stringers are one of three curved staircase design options that we at Acadia Stairs offer.

Also known as pan-style stairs, curved side stringers have supportive beam-like structures on each side of the stair, and riser plates in addition to tread plates. The term pan-stair comes from traditional cement-fill pan-type stairs, but these pans can be made to receive stone, wood or even glass steps.

Customizable Staircases

Curved pan stairs are completely customizable. Our design team will work with you to fit your space, style, and traffic pattern.

  • Can be attached to a side wall or free-standing
  • Prominent feature is the stringer or skirt
  • Ribbon-like appeal as they flow up the curvature of the staircase
  • Wide variety of tread options available

This type of stair typically has the handrail installed outboard of the stringer or in-line with the stringer. It is possible to have the balusters attach to the treads, but it is more common to attach to the stringer alone.

Curved Side Stringer Stair FAQs

What is a curved side stringer staircase?
A curved side stringer staircase uses structural stringers mounted along the sides of the stair treads while following a curved path. The side stringer design provides strong support while allowing the staircase to maintain a sleek and open architectural appearance.
How is a side stringer different from a center stringer staircase?
A center stringer staircase supports the treads from a single beam located beneath the center of the stair. A side stringer staircase instead uses structural supports on the outer edges of the treads, which can provide additional stability and allow for different railing and tread configurations.
Can curved side stringer stairs support heavy materials like hardwood or stone?
Yes. Curved side stringer staircases are engineered to support a wide range of tread materials including hardwood, metal, glass, and stone. The dual side support structure helps distribute weight evenly across the staircase.
Are curved side stringer staircases custom built?
Absolutely. Every curved staircase must be custom designed to match the exact radius, rise, run, and layout of the space. Fabrication is typically done using precision steel forming to achieve the correct curve and structural strength.
What types of spaces work best for curved side stringer stairs?
Curved side stringer staircases are commonly used in modern homes, luxury residences, commercial buildings, and architectural spaces where both strength and visual impact are important. Their flowing design makes them ideal for entryways, atriums, and open floor plans.
