A is a structural system where two parallel beams, typically positioned under or at the outer edges of the treads, act as the primary load-bearing members . Unlike a mono-stringer which uses a single central spine, the double stringer configuration offers enhanced lateral stability, reduced vibration, and a more balanced architectural profile. Key Components of a Double Stringer DWG Detail
For stringers: use 25–30 MPa concrete, design as inclined beam with main tension reinforcement along bottom, stirrups for shear.
A double stringer staircase uses two structural supports (stringers) running along the sides or underneath the treads to provide stability and a distinct aesthetic. In architectural and structural drawings, a comprehensive typically includes section views, connection methods for the base and landings, and specific material callouts. Core Components of a Double Stringer Detail
: Two stringers can typically support a staircase up to 36 inches wide ; wider stairs may require a third central stringer.

The structural backbones running the length of the flight. They can be exposed structural steel channels, rectangular hollow sections (RHS), welded plate girders, or heavy timber.
Q: What is the minimum width for a double stringer staircase? A: The minimum width for a double stringer staircase is typically 36 inches, but can vary depending on the specific application and local building codes.
The StructuralDetails library allows for easy adjustments to tread thickness, rise/run, and material choice. Typical Application Scenarios Double stringer staircases are highly versatile:
A-STAIR-DIMS : Dimensions, extension lines, and callouts (Continuous, Fine weight). A is a structural system where two parallel
A double stringer staircase features two parallel structural beams—known as stringers—running on either side of the steps to support the treads and risers. Unlike mono stringer stairs which use a single central beam, double stringers distribute the load evenly across both sides. Key Component Anatomy
Offers comprehensive structural CAD drawings for steel staircases with concealed tread steps.
Several architectural platforms provide comprehensive DWG templates and instructional content:
: Steel angles or plates welded to the stringers to support the individual treads. A double stringer staircase uses two structural supports
: Pre-made DWG files from the internet may not match your local jurisdiction's latest egress or guardrail height mandates. Always manually cross-reference dimensions.
The stringers are inset slightly from the edges of the treads, creating a floating effect while maintaining dual-beam rigidity. 2. Key Structural Components in a DWG Detail
What are you prioritizing? (e.g., steel channels, laser-cut plates, or timber?)
When mixing materials (e.g., steel stringers with timber treads), allow for material movement.
