The main structural supports, usually made from steel channels, rectangular hollow sections (RHS), or engineered wood.
This story follows Alex, a junior architect tasked with designing a "floating" feature staircase for a modern office lobby. To ensure the design was both beautiful and structurally sound, Alex needed a precise double stringer staircase detail The Challenge: Form vs. Function
Open-riser double stringer designs permit natural light to pass through the structure, making tight interior spaces feel larger and more connected. double stringer staircase detail dwg free
The vertical space between treads (often left completely open in modern double stringer designs).
: For double stringer stairs, the width is typically limited to 36 inches before a third (center) stringer is required to prevent sagging . The main structural supports, usually made from steel

When drafting or reviewing a double stringer staircase in a DWG file, several critical components must be clearly detailed and labeled: A. The Stringers (The Structural Beams) 6-foot-tall rear deck needing a double stringer stair
Word spread. An architecture student, Lara, downloaded the DWG to study its elegant joinery; a community center in town saw potential to replace their rickety stairs; an independent maker created a CNC-ready kit from the CAD layers. In the comments, people debated interpretation of the handrail curvature and the best finish to protect the exposed steel stringers. Each person who used the file left a note of thanks.
The vertical gaps between treads. In modern double stringer designs, these are frequently left open to allow light filtration. Architectural and Engineering Advantages
The detail should show how the handrail posts attach to the stringers. Side-mounted (fascia-mounted) posts bolted to the outside of the stringer preserve the clear walking width of the stairs. What to Look for in a Free DWG Download
Not all free CAD files are drafted equally. A high-quality, professional-grade detail drawing should include the following structural specifications: Connection Details
