Arc Roof Truss Detail Design with 21.78 m Span Metal Structure

This Arc Roof Truss Detail Design AutoCAD drawing shows a complete curved metal roof structure with a clear span of 21.78 meters. The drawing illustrates reinforced steel profiles, a triangular truss configuration, and curved geometry designed for long-span roofing applications. Key elements include steel angle profiles, circular metal tubes of 7 cm diameter, anti-corrosive paint coating, and precise member connections. The roof covering system is detailed with polycarbonate opaque sheets, metal sheet lining, and calamine roofing, ensuring durability and weather protection. Dimensional annotations and slope indications support accurate fabrication and structural planning.

The detailed roof structure section further explains groove alignment, gutter placement, roof cover fixing method, and integrated lighting system using mercury vapor lamps with iodide additives. Connection details show the relationship between primary truss members, secondary supports, and roof covering layers. Material thicknesses such as steel profiles sized 15 x 7 cm and 4 x 4 cm are clearly indicated, making the drawing suitable for execution-level documentation. This AutoCAD DWG file is ideal for architects, civil engineers, interior designers, and builders working on industrial sheds, halls, and large-span roof structures using AutoCAD, 3D Max, Revit, and Google SketchUp.
