Comprehensive Guide to Double Stringer Staircase Details (With DWG Resources)
A standard, low-quality CAD block can lead to fabrication errors. A professional-grade should feature: 1. Plan View (Top-Down) Exact staircase width and total run. Stringer centerline dimensions relative to the walls. Tread depth and nosing projections. Handrail and guardrail alignments. 2. Elevation/Section View Total finished floor-to-floor height. Precise calculation of individual rise and run dimensions. Stringer pitch angle (typically between 30 to 38 degrees). Clearance heights (minimum 6'-8" or 80 inches of headroom). 3. Connection and Mounting Details
The stringers remain straight, solid diagonal beams. Treads are mounted via welded interior cleats or brackets, keeping the outer side of the beam perfectly smooth. 2. Under-Tread (Centered) Double Stringers
