3D Spiral Staircase DWG with Metal Railing and Concrete Slab Design

This AutoCAD DWG file provides a detailed 3D design of a spiral staircase, featuring metal railings and concrete slab steps with precise dimensions. The drawing illustrates the complete staircase layout, including landing positions, step heights, and railing placements for structural stability. Architects, civil engineers, interior designers, and builders can use this file to visualize and plan spiral staircase installation for residential, commercial, or industrial projects. The 3D model allows for accurate assessment of space, slope, and construction feasibility, ensuring safe and functional design. Each component, including treads, the central support column, and handrails, is annotated with measurements and material specifications to assist in fabrication and on-site installation. This DWG file is compatible with AutoCAD, 3ds Max, Revit, and SketchUp, allowing integration into architectural projects and design workflows. Professionals can use the model for material estimation, construction planning, and 3D visualization of the staircase. The file is essential for designers needing a complete, detailed, and practical reference for 3D spiral staircase projects.
