Buying Guide
Key considerations when choosing 8′ stair stringers:
- Deck height and number of steps: Ensure the stringer length and step count match your exact rise-to-run ratio.
- Material and finish: Steel with powder coating resists rust and weathering; galvanized steel adds extra durability for outdoor use.
- Pre-drilled holes and hardware: Pre-drilled holes simplify installation; check whether screws, expansion bolts, or nuts are included.
- Load capacity: Consider total load, including treads, occupants, and furniture. Some models list 5000+ lbs; verify for residential use.
- Wood tread compatibility: Some stringers require separate wooden treads; confirm tread availability or compatibility before purchase.
- Local codes: Always verify with local building codes or a professional to ensure compliance for outdoor stair installation.
