Double Stringer Staircase Detail Dwg Access
The most common stringers for residential interiors. They are usually cut from a 2x12 and notched to support treads and risers (cut stringers). For added strength in wide spans, double LVL or 2x12 stringers can be sistered together.
In modern residential and commercial architecture, the has emerged as a premier choice for combining structural integrity with minimalist elegance. Often used in exposed steel or high-end timber applications, this design features two structural stringers—typically positioned under the treads or on the outer edges—providing a robust, clean, and often floating aesthetic.
The bottom connection resists both downward vertical loads and outward horizontal thrust. Show a base plate welded to the bottom of the stringers.
When downloading or drafting a double stringer staircase detail in AutoCAD or other CAD software, your DWG file must capture several critical elements: Structural Stringers
Plates welded or bolted to the stringers that physically hold the treads. double stringer staircase detail dwg
Drafting these details requires adherence to strict architectural rules to ensure the stairs are safe for daily use:
Structural members usually made from steel channels (C-channels), rectangular hollow sections (RHS), or plate steel. They can be placed directly under the edges of the treads (outer stringers) or tucked slightly inboard for a floating effect (under-slung stringers).

A double stringer staircase is a type of staircase that has two stringers (also known as string boards) that support the treads and risers. Here is some detailed content that you can use to create a Double Stringer Staircase detail in DWG (AutoCAD) format: The most common stringers for residential interiors
The DWG file should contain the following:
When reviewing a double stringer detail, ensure the following are included for a complete set: Plan View: Shows total width, landing depth, and tread count. Section View: Illustrates the riser height (vertical) and tread depth (horizontal). Nosing Details:
: Callouts for steel grades (e.g., A36 or A500) and welding specifications. Best Practices for Using DWG Stair Details
Here, the stringers sandwich the treads, framing them on the left and right sides. Treads are either bolted to brackets welded to the inside face of the stringers or slotted into machined grooves. In modern residential and commercial architecture, the has
How the base fixes to the foundation slab (typically a welded base plate with expansion anchors).
Complete Guide to Double Stringer Staircase Details in CAD Double stringer staircases are a staple of modern architectural design. They offer an ideal balance of structural stability and minimalist aesthetics. For architects, engineers, and fabricators, having an accurate is essential for ensuring precise manufacturing and code compliance.
The double stringer often acts as the mounting base for the guardrail system.
A double stringer staircase is a type of staircase that features two stringers, typically made of steel, wood, or concrete, that run along both sides of the stairs. These stringers provide support to the treads and risers, ensuring the staircase is structurally sound and safe for use. Double stringer staircases are commonly used in commercial and industrial settings, such as office buildings, shopping malls, and warehouses, where heavy foot traffic and high loads are expected.
A minimum clear height of 6 feet 8 inches measured from the tread nosing to the ceiling overhead.
By ensuring your accounts for proper steel section sizing, accurate tread-to-stringer connections, and rigid code compliance, you can confidently transition your design from a digital drawing into a striking architectural centerpiece.
