Months later the courthouse reopened. The double stringer stood, newly dressed in elm and brass, the rope handrail installed with careful knots. People climbed it like they had always done, but some paused on the third tread, where a small plaque had been placed: FOR LUCAS — KEEP CLIMBING.

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. double stringer staircase detail dwg

To ensure your DWG file is easy to edit, scale, and integrate into larger master architectural plans, organize your layers cleanly:

Here are the essential elements you should look for in a 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.

A high-quality double stringer staircase detail DWG typically includes:

: Detail the specific timber members and connections, often including L-angle plates for fixing the stringers to the ground and landings. Adaptability

What you plan to use for the stringers (HSS box sections, PFC channels, or flat plates)?

2R + T = 600–630 mm (24–25″)

A double stringer (or dual stringer) system consists of two structural members—typically steel channels (UPN/C-channel), rectangular tubes, or timber beams—running along the outer edges or slightly inset from the sides of the treads. In a standard DWG detail , you will typically find:
