Circular Stairway Design Detail with Steel Connector Drawing

This Circular Stairway Design AutoCAD drawing provides a complete set of plan views, elevations, sections, and construction details for a curved stair system. The drawing includes circular stair layout geometry, step arrangement, riser and tread proportions, and handrail alignment. Structural components such as steel connectors painted with automotive support color, aluminium thin elements, and fixing brackets are clearly illustrated. The stair plan shows radial dimensions, center pivot alignment, landing connections, and guardrail positioning, allowing accurate fabrication and installation of the circular stairway.

The detailed stairway drawing further explains solid wood handrails finished in natural maple, baluster spacing, steel plate connections, and anchoring details to floor slabs. Section drawings highlight step thickness, structural support members, and safety railing heights. Multiple detail callouts present bolt connections, joint treatments, and material transitions between steel, wood, and aluminium components. This AutoCAD DWG file is useful for architects, civil engineers, interior designers, and builders involved in residential and commercial stair design. The drawing is compatible with AutoCAD, 3D Max, Revit, and Google SketchUp, supporting precise drafting, coordination, and construction documentation for circular stairway projects.
