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 DWG detail typically includes section views, connection methods for the base and landings, and specific material callouts. Core Components of a Double Stringer Detail
Stringer Profiles: Often made of steel UPN or IPE sections for modern industrial looks.
Tread Connections: Can be "concealed" (treads tucked between stringers) or "raised" (treads sitting on top).
Support Points: Details for the ground floor foundation, middle landings, and top floor main supporting beams.
Safety Standards: Standard riser heights typically fall between 15–18 cm, with a step depth of 25–30 cm. Design and Drafting Considerations
Stability: Two stringers can typically support a staircase up to 36 inches wide; wider stairs may require a third central stringer.
User Comfort: Use the 17/18 rule (rise + run = 17 or 18 inches) to ensure a natural walking rhythm.
Aesthetics: Double stringers allow for an "open riser" look, which creates a sense of light and airiness in modern homes. Resources for DWG Files

What is a Double Stringer Staircase?
A double stringer staircase is a type of staircase that uses two side stringers, each supporting the treads and risers, instead of a single central stringer. This design provides additional structural support and is often used in modern architecture.

Detailing a Double Stringer Staircase in DWG:
When creating a double stringer staircase detail in DWG (AutoCAD), you'll want to include the following:

A double stringer staircase (or dual stringer) utilizes two structural support beams placed on either side of the stair treads to distribute weight evenly. This configuration is the industry standard for commercial and industrial settings but is also a popular choice for high-end residential "floating" stairs due to its stability and framed aesthetic. Key Technical Details for DWG Drafting
When creating or downloading a CAD detail for these stairs, professional drawings typically include the following components:
Stringer Profiles: Steel designs often use structural shapes like UPN channels, HSS tubes, or flat plates.
Connection Points: Detailed sections must show the stringer baseplate floor connection, middle landing supports, and the connection to the top floor's main supporting beams.
Tread Support: Details specify how treads are attached—often via steel L-angle plates for timber or welded brackets for steel.
Dimensions: Standard layouts follow the 7-11 rule (7-inch riser, 11-inch tread) or the 27 rule (riser + tread = 27 inches) to ensure ergonomic safety. Resources for CAD Files & Articles
Several architectural platforms provide comprehensive DWG templates and instructional content:
A double stringer staircase features two parallel support beams (stringers) running on either side of the treads, providing exceptional stability and a balanced aesthetic. These are commonly used in modern residential and industrial designs, often utilizing steel profiles like U-channels (UPN), square hollow sections (SHS), or flat plates. Key Technical Components for DWG Detailing
To create a "proper" professional staircase detail in CAD, your drawing should include the following specific elements:
Stringer Profiles: Specify the exact dimensions, such as a C12 x 20.7 channel or similar structural steel section.
Tread Connections: Show how the tread attaches to the stringer. Common methods include:
Concealed Steps: Treads are hidden within the height of the stringer for a flush, modern look.
Raised Treads: Treads sit on top of the stringers, often using steel angle brackets (e.g., ) for support. Top & Bottom Connections:
Top: Detailing the connection to the floor slab or beam. "Cranking" the stringer at the top to create a short horizontal section is a safer practice than connecting directly to a beam heel.
Bottom: Use base plates with anchor bolts to secure the stringers to the structural floor. Standard Proportions & Code Requirements
When setting up your DWG layout, adhere to these common engineering and safety standards:
The 7-11 Rule: A standard for safe steps is a 7-inch riser and an 11-inch tread. double stringer staircase detail dwg
The 27 Rule: For a comfortable rhythm, the sum of one riser and one tread should approximately equal 27 inches (e.g., 7" riser + 20" tread).
Stringer Spacing: For standard two-stringer setups, the stair width should typically not exceed 36 inches without a middle support to prevent sagging.
Nosing/Overhang: Most codes require treads to overhang risers by 3/4" to 1-1/4".

In the world of architectural design and structural engineering, staircases are often the most complex components of a building to detail. Among the various structural supports, the double stringer staircase stands out as a gold standard for durability and load distribution. While single stringer (mono-stringer) or closed stringer designs have their place, the double stringer configuration—featuring two inclined beams supporting the treads from below or the sides—offers an unparalleled balance of strength, material efficiency, and design flexibility.
But a theoretical understanding is useless without precise execution. This is where the Double Stringer Staircase Detail DWG becomes the most critical file in your CAD library. A well-drafted DWG (AutoCAD Drawing) file captures not just geometry, but material specifications, weld points, bolt connections, and compliance with the International Building Code (IBC) or local standards.
This article will dissect the double stringer staircase from concept to CAD, focusing on how to create, read, and implement a high-quality detail DWG.
When designing a modern interior, the double stringer staircase
is a go-to for architects looking for a balance between industrial strength and minimalist aesthetics. Unlike mono-stringers, the dual-beam support offers increased stability and allows for wider tread spans without the bounce often associated with single-support designs. Key Technical Details in a DWG File A professional-grade double stringer staircase detail DWG
typically includes several critical components for construction and fabrication: Stringer Profiles
: Often specified as steel channels (e.g., UPN260 or MC shapes) or rectangular hollow sections (HSS). The drawing will detail the specific pitch and cut of these beams. Tread Support Brackets
: Details on how the treads are mounted—whether they are "raised" on top of the stringers or "concealed" between them for a sleeker profile. Structural Connections
: Precise details of the top floor main beam connection and the ground floor foundation or starter plate. Material Transitions
: Specifications for the interface between the steel stringers and wooden or glass treads. Architectural Gallery
These visual references showcase various double stringer configurations, ranging from heavy timber frames to sleek, laser-cut steel designs.
The "story" of a double stringer staircase is one of transition from hidden support to architectural centerpiece. While traditional stairs often hide their structure behind walls, the double stringer design celebrates engineering by putting the "skeleton" on display. The Evolution of the Double Stringer
Historically, grand staircases used massive stone or timber to impress guests. However, the modern double stringer—characterized by two parallel beams supporting treads from the sides or underneath—emerged as a way to combine transparency with strength.
