Q: What is the staircase width specification?: 7, security: staircase components should be smooth, rounded, no prominent, sharp parts. There are children of the elderly family, the stairs slope to be slow, the rotation angle can not be too large; staircase pedal to do anti-slip measures, such as non-slip, anti-skid pads, non-slip groove. 8, residential staircase stepping size: 150 ~ 175, 260 ~ 300 9, primary and secondary school staircase step size: 120 ~ 150, 260 ~ 300 10, office staircase stepping size: 140 ~ 160, 280 ~ 340 11, kindergarten staircase step size: 120 ~ 140, 260 ~ 280 12, nursing home staircase step size: 150 300 13, the theater, the hall staircase step size: 160 130 ~ 150, 300 ~ 350 14, according to the size of the staircase between the staircase width B and ladder width. 15, to determine the step number of curse, adjust the stepping high chu and step width b, with a layer of high H divided by stepping high h, step step n ≈ H / h, when the decimal, when the integer, and adjust the step high h (H ≈ H / n), using the formula b + h = 450 (mm), or b + 2h = 600 ~ 620 (mm), determine the step width b.
