Description

This steel stair construction CAD block is a construction detail, 70′-6½″ × 91′-7¼″ (21,500 × 27,921 mm), drawn at full size.

Both versions, inches and millimeters, are DWG files that open in AutoCAD 2000 or newer; insert either one at scale 1 and it lands at its real size. In an imperial drawing insert cadgrid-steel-stair-construction-details_in.dwg; in a metric one, cadgrid-steel-stair-construction-details_mm.dwg. No scaling is needed in either case.

Residential stairs under the IRC have risers of 7¾″ (197 mm) at most, treads of at least 10″ (254 mm), handrails 34–38″ (864–965 mm) high and 6′-8″ (2032 mm) of headroom.

Working outside CAD? The same drawing also comes as a DXF for other CAD programs, a PDF for printing, a PNG with a transparent background for slides and mood boards and an SVG you can edit in Illustrator, Inkscape or Figma.

Common questions

What size is the steel stair construction drawn at?

It measures 70′-6½″ × 91′-7¼″ (21,500 × 27,921 mm) in detail, taken from the outer edges of the drawing. The page shows the same sizes in both units next to the drawing.

Do I need to scale the block when I insert it?

No. cadgrid-steel-stair-construction-details_in.dwg is drawn in inches (INSUNITS 1) and cadgrid-steel-stair-construction-details_mm.dwg in millimeters (INSUNITS 4). Insert the one that matches your drawing at scale 1 and the block comes in at its real size.

What are the code limits for residential stairs?

Under the IRC: risers no higher than 7¾″ (197 mm), treads at least 10″ (254 mm) deep, handrails 34–38″ (864–965 mm) high and 6′-8″ (2032 mm) of headroom. Guards are 36″ (914 mm) high in homes and 42″ (1067 mm) under the IBC.

Can I use this steel stair construction outside AutoCAD?

Yes. Use the DXF in other CAD programs, the PNG with its transparent background in slides, documents and mood boards, the SVG to edit it in Illustrator, Inkscape or Figma, and the PDF to print it or send it to someone without CAD.
