Double Stringer Staircase Detail Dwg -

A is a structural system where two parallel beams, typically positioned under or at the outer edges of the treads, act as the primary load-bearing members . Unlike a mono-stringer which uses a single central spine, the double stringer configuration offers enhanced lateral stability, reduced vibration, and a more balanced architectural profile. Key Components of a Double Stringer DWG Detail

: Points of attachment for balustrades, which can be side-mounted directly to the stringers for a clean look. Technical Design Considerations

: Usually angle irons or flanged plates that are welded or bolted to the stringers to hold the tread in place. double stringer staircase detail dwg
