Double Stringer Staircase Detail Dwg Jun 2026

C10 or C12 sections are common for high-traffic areas.

If you'd like, I can suggest specific types of stringers or materials to use based on your project requirements.

A complete, construction-ready DWG file must look beyond a basic side profile. To be highly functional for fabricators, ensure your file contains the following detailed views and callouts: A. Base Connection Detail (Footing)

Double stringer staircases are not just structural solutions—they are also an expressive architectural element. Notable projects demonstrate how steel, timber, glass, and other materials can be combined with dual stringers to create sculptural and beautiful stairs:

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:

Detail a bolted connection using high-strength structural bolts (e.g., A325 bolts) fastening directly to a structural header beam. Bottom Footing Detail (Base Connection)

must be maintained along the entire pitch line of the stairs.

Top (header) plates and bottom (footing) plates for anchoring to floors. C10 or C12 sections are common for high-traffic areas

: Detailed specifications for different finishes, including concealed wooden planks (tucked inside the stringer height) or raised wooden steps (sitting above the beam).

Q: Can I use a double stringer staircase detail DWG for a curved staircase? A: While a double stringer staircase detail DWG can be used as a starting point for a curved staircase, it may require modifications and additional calculations to ensure accuracy and safety.

Shows how the stringers attach to the concrete slab or structural subfloor via embedded anchor bolts and base plates.

When drafting these details in AutoCAD or Revit, your DWG must account for specific tolerances and building codes (such as IBC or IRC). 1. Stringer Profiles and Dimensions To be highly functional for fabricators, ensure your

You can find downloadable templates and technical drawings at these professional libraries:

: Usually angle irons or flanged plates that are welded or bolted to the stringers to hold the tread in place.

While DWG is the industry standard for 2D shop drawings, the AEC industry is moving toward BIM (Building Information Modeling). When you create your double stringer detail:

Remember: A great detail shows every weld, every bolt, every edge distance, and every material callout. It respects the fabricator's need for clarity and the engineer's need for precision. So next time you open your CAD software, spend the extra hour on that 1:2 scale connection detail—your stairs will stand silent and strong for decades.

This detail shows how the top of the staircase attaches to the upper floor joist or landing beam.

By distributing the load across two members, these stairs can span greater distances without intermediate supports.
