How to calculate U-Shaped Stair with Winders?
- Step 1. Choose the measurement units, DU — mm, cm, m, inches, feet.
- Step 2. Choose the drawing color, CL — monochrome, color.
- Step 3. Choose the staircase type — left turn, LF, right turn, RG.
- Step 4. Choose how to calculate total run — along upper stairway, FTP, along intermediate stairway, FMD, along lower stairway, FBT.
- Step 5. Input the stair, stairwell dimensions — total rise, Y*, total run, X, stairway width, Z.
* from the 1nd floor level to the 2nd floor level
* total rise = stairwell height (if top step is on the 2nd floor level) - Step 6. Choose type of winder steps connection to newel post — tongue and groove joint, LOC, mounting inside the newel post, INT.
- Step 7. Input the steps parameters — number of steps on upper stairway, QT, number of steps on intermediate stairway, QM, number of steps on lower stairway, QB, thickness, SW, nosing, SF*.
* nosing = tread overlap - Step 7.1. Select to install the top step below 2nd floor level or keep it at the 2nd floor level, SP.
- Step 8. Select to install risers or not, H.
- Step 8.1. Input the risers parameter — thickness, HT.
- Step 9. Input the stringers parameters — thickness, T, width, WI.
- Step 10. Input the stringers with winders parameters — thickness, IT, width, IW.
- Step 11. Input the support joists parameters — thickness, JT, width, JW.
- Step 12. Input the support posts parameter — width, SB.
- Step 13. Input the balustrade parameters — baluster width, BA, baluster height, RH, handrail thickness, RT, handrail width, RW.
- Step 14. Input the upper floor slab parameter* — thickness, ST.
* required for visualization only - Step 15. Input the wall parameter* — thickness, WT.
* required for visualization only - Step 16. Please check all entered values, click the «Calculate» button and get a U-Shaped Stair with Six Winders design.
