How to calculate U-Shaped Stair with AUTO 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 the staircase construction mode — fixed total run, EX, fixed total run №1, intermediate total run and total run №2 are calculated automatically, EB, fixed intermediate total run, total run №1 and №2 are calculated automatically, EM, fixed total run №2, intermediate total run and total run №1 are calculated automatically, ET.
- Step 5. Input the stair, stairwell dimensions — total rise, SH*, stairway width, SW, opening between stairways, MD**, length along lower stairway, LB, length along lower stairway, LT.
* from the 1nd floor level to the 2nd floor level
* total rise = stairwell height (if top step is on the 2nd floor level)
** opening between stairways = intermediate stairway length - Step 6. Input the steps parameters — rise, DH, thickness, SC, nosing, SF*.
* nosing = tread overlap - "Step 6.1. Input the winder steps parameters* — minimum tread depth at the connection to the support post, MW, minimum tread depth at the connection to the stringer, MF.
* more details in the image below - Step 6.2. Select to install the top step below 2nd floor level or keep it at the 2nd floor level, SP.
- Step 7. Select to install risers or not, H.
- Step 7.1. Input the risers parameter — thickness, HT.
- Step 8. Input the stringers parameters — thickness, T, minimum throat depth, WI, quantity, QT*.
* standard stair — 2 pcs (by default)
* custom stair — 3-5 pcs
* mono stringer stair — 1 pcs - Step 9. Input the upper floor slab parameter* — thickness, ST.
* required for visualization only - Step 10. Input the wall parameter* — thickness, WT.
* required for visualization only - Step 11. Please check all entered values, click the «Calculate» button and get a U-Shaped Staircase with Winders (AUTO pcs) design.
