Rectangular Steel Tubing (HSS) such as 6" x 2" or 8" x 2" options are favored for sleek looks. Plate steel (e.g., 1/2" thick laser-cut profile stringers) provides a highly modern jagged profile matching the steps.
Double stringer staircases are a hallmark of modern architecture, offering a perfect balance of structural integrity and minimalist aesthetics. Unlike traditional stairs where the support structure is hidden beneath the risers and treads, a double stringer system exposes two robust beams (stringers) running along either side of the stairs to support the treads.
Showing the overall width of the stair, landing dimensions, and handrail placement.
Double stringer staircases are a hallmark of modern architecture. They blend structural integrity with a clean, contemporary aesthetic. Whether you are an architect detailing a high-end residential project or a fabricator looking for precise shop drawings, understanding the anatomy of a double stringer system is critical. double stringer staircase detail dwg free
Double stringer staircases are a hallmark of modern architecture. They offer exceptional structural stability while maintaining a clean, open, and minimalist aesthetic. For architects, structural engineers, and draftsmen, having an accurate CAD drawing (DWG) of this detail is essential for precise construction modeling and fabrication.

Often designed without risers (open-riser stairs) to allow light to pass through the space. Rectangular Steel Tubing (HSS) such as 6" x
Finding high-quality, free requires looking for files that include structural connections, material profiles (like UPN or SHS), and precise tread details. A double stringer design uses two parallel beams on either side of the treads to distribute weight evenly, making it ideal for wider or modern floating staircases.

A comprehensive collection of staircase detail drawings is available. These professional packages include floor plans, detailed section views, dimension grids, and construction details for treads, risers, and handrails. This resource is widely used for design reference and as a template for further technical development.
