Single Stringer Staircase Detail Dwg – Premium & Essential

Unlike double stringers that resist torsion (twisting) naturally, a single stringer must handle:

If you describe your (steel vs concrete, residential vs commercial, tread material), I can write a detailed drafting checklist tailored to your DWG. single stringer staircase detail dwg

| Error | Consequence | Fix in Your DWG | | :--- | :--- | :--- | | | Stringer rolls over when loaded on one side. | Add horizontal stiffeners or use a box section. | | Missing weld symbols | Fabricator uses undersized welds. | Explicitly call out "6mm fillet weld, full length." | | No landing connection moment | Creaks, movement at top landing. | Specify a moment connection (not just a pin). | | Inadequate concrete embedment | Base plate pulls out of slab. | Increase anchor bolt embedment to 150mm min. | | No consideration for finish thickness | Finished tread clashes with riser face. | Show both structural tread (steel pan) and finished tread (wood/stone). | | | Missing weld symbols | Fabricator uses undersized welds

This article serves as a technical deep dive. We will cover the engineering principles, material choices, connection methods, and step-by-step guidance on what to look for (or draw) in a file. | | Inadequate concrete embedment | Base plate
