Do Stair Stringers Need to Be Supported Along Their Length?
Stair stringers are the structural members of a staircase that support the treads and risers. They are typically made from metal, wood, or composite materials, and are installed in an inverted “V” shape with one end at the top of the stairs and one end at the bottom. It is important to consider whether or not they need to be supported along their length when constructing a staircase.
Sizing Stair Stringers for Adequate Support
In most cases, stair stringers do not need additional support along their length if they are adequately sized for the application. A stringer should be sized according to local building codes and industry standards, taking into account factors such as weight load and rise/run ratio. If this is done correctly, then additional supports are usually unnecessary. However, there may be instances where additional support is needed due to excessive loads or uneven terrain.
4. Consider additional supports if extreme loads or uneven terrain are present.
In some cases, additional support is necessary even if the stringers have been properly sized for their application. This could include areas where extreme loads exist (such as near a hot tub or sauna) or areas where seismic activity is high (such as near an earthquake-prone area). In these instances, it is important to use adequate supports
7 tips
1. Always consult local building codes and industry standards when sizing stair stringers.
2. Take into account factors such as weight load and rise/run ratio when sizing the stringers.
3. In most cases, additional support is not needed for properly sized stringers.
4. Consider additional supports if extreme loads or uneven terrain are present.
5. Use adequate supports if the staircase is located in an earthquake-prone area or near a hot tub or sauna.
6. Make sure any supports used are properly secured to the stringer and underlying structure to ensure stability and safety of the staircase.
7. Regularly inspect the stair stringers for signs of wear and tear, and replace them as needed to prevent failure or collapse of the stairs over time
