Combining the grace of a spiral with the clean lines of modern engineering, this style offers a "best of both worlds" solution for homeowners and architects looking to make a statement without sacrificing space.
Unlike traditional stairs that might hide their structure behind drywall, double stringer systems celebrate their engineering, often leaving the "skeletons" of the staircase visible to create an open, airy feel. What Defines a Curved Double Stringer Staircase? curved double stringer staircases
Bending steel is an art form. Achieving a perfect, smooth curve in a structural steel beam requires heating and hydraulic manipulation or cutting the curve from a thick plate of steel and welding the profile. This labor-intensive process makes curved double stringers significantly more expensive than straight stairs. Combining the grace of a spiral with the
A curved double stringer staircase is characterized by two parallel stringers, or supporting beams, that curve to form the staircase's elegant, sweeping shape. The stringers are typically made from steel, wood, or a combination of both, and are carefully crafted to support the weight of the staircase and its users. The curved design requires precise calculations and skilled craftsmanship to ensure a smooth, flowing shape that is both aesthetically pleasing and structurally sound. Bending steel is an art form
Because the stringers are anchored only at the top and bottom (and sometimes the side walls), a curved steel stringer can act like a giant spring. Engineering is critical here; the gauge of steel must be calculated precisely to prevent the staircase from swaying or vibrating when walked upon.
Each stringer is engineered to match the exact curve of the space, resulting in a smooth, continuous flow from floor to floor. Top Benefits of the Double Stringer Design
