Study Notes
Purpose of Stringers
- Stringers provide structural support for the steps, distributing weight evenly.
- They create the framework that holds treads and risers in place.
Number of Stringers
- Each set of steps typically contains three stringers to enhance stability and safety.
- The third stringer helps prevent sagging and ensures even load distribution.
Measuring Stringers vs. Treads/Risers
- Stringers are measured based on the total rise and run of the steps, considering the angle of the slope.
- Treads are measured in width and depth, typically the horizontal part where foot traffic occurs.
- Risers are measured in height, determining the vertical distance between each tread.
Calculating Handrail Length
- The length of the handrail can be determined by assessing the total rise of the steps and the angle of inclination.
- Measurements should account for the overall slope and any additional features like turns or landings.
Bidding Considerations for Handrails
- In addition to materials and labor, consider safety codes and regulations that govern installation.
- Assess installation complexity, potential obstacles, and any required finishing work.
- Factor in maintenance needs and durability of materials selected for the handrail.
