How to calculate Two-Quarter-Turn U-Shaped Stair with Six Winders (3+3 pcs)?
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 overlapStep 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 onlyStep 15. Input the wall parameter* — thickness, WT.
