Exterior stairs need coating discipline. Galvanizing, drainage, slip resistance, and bolted field connections should be planned as part of the stair, not after it.
Start with structure, not style
The finished stair can look minimal, but the steel behind it needs clear load paths, connection points, and a guard strategy before fabrication starts.
- Opening dimensions
- Floor-to-floor height
- Tread material
- Guard and handrail type
- Finish and installation access
Buildability decides the final detail
A beautiful stair still has to enter the building, line up with finished floors, and accept the railing system without field improvisation.
