The life of a curve

One special and very specific type of curved stair is the Double Helix Stair. With all due respect to James Watson and Francis Crick (who recently celebrated 50 years since their discovery of the DNA structure), we feel that our Double Helix Stair can be one of the building blocks of a beautiful home or office.

Often referred to as a spiral stair without a center column, the dramatic look, grace, and beauty of this stair is unparalleled.

Benefits of the double helix stair include: handrails on both sides, greater tread widths ( normally 36" wide), and little "roomier" stair - people often need a spiral type stair but want a stair that offers a larger radius than one gets when walking up around the center column on a standard spiral.

These stairs demand a strong stringer to carry the load and we can fabricate from either metal (steel, aluminum, stainless) or wood (oak, cherry, maple, mahogany, and more). Additionally, specific drawings, design, and engineering is usually required to ensure that our custom-built stairs will perform properly and that your structure will accommodate the load.
