How to Calculate Concrete Spiral Stair?
- 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. Input the stair, stairwell dimensions — total rise, Y*, staircase diameter, D**, staircase internal diameter, ID, rotation angle, RA.
* from the 1nd floor level to the 2nd floor level
* total rise = stairwell height (if top step is on the 2nd floor level)
** staircase diameter = stairwell diameter - Step 5. Input the steps parameter — quantity, Q.
- Step 6. Please check all entered values, click the «Calculate» button and get a Spiral Concrete Staircase design.
