This creates a cantilevered visual effect on the outer edges of the steps, making the staircase appear lighter and more floating. 📐 Critical Technical Specifications for CAD Drafting

: The "heel" of the stringer must fully bear (at least 1.5 inches) on the landing or header to prevent shearing .

Not all CAD files are created equal. When you download a free DWG for a double-stringer staircase, you must ensure it contains the critical details that will pass a plan check and guide construction.

Lightweight, open-riser design that allows light to pass through, making spaces feel larger.

The two primary load-bearing beams running diagonally from the lower floor to the upper landing. They are commonly made from structural steel channels (C-channels), rectangular hollow sections (RHS), or plate steel. double stringer staircase detail dwg free

The steel plate is cut in a zigzag pattern matching the rise and run. The treads sit flat on top of these cuts.

Often used in traditional or rustic-modern designs. Requires thicker dimensions (typically 45mm to 70mm minimum thickness per stringer) to prevent twisting and deflection. 2. Connection Details

Welding symbols indicating continuous fillet welds for bracket connections.

The stringers are positioned inboard, tucked directly underneath the treads. This conceals the supports from the side view, giving the treads a "floating" appearance. It requires robust welding and precise brackets to prevent lateral wobble. 2. Side-Slung (Exposed) Stringers
