Description

Schotten & Hansen manufactures steps and staircases to match and complement individual design concepts. Grain selection, finish and coloration can be harmonized with flooring or any other wooden interior elements to create precious spaces.

Essential for the physical effort when climbing a stair is the rise ration S/A, which is derived from the inseam of an adult human. This is on average 63 cm. For the definition of a slope ratio with low energy requirements, the formula is: 2 S + A = 63cm. The for humans physiologically cheap „Get Work“ is given at an inclination angle of the staircase of 30 ° and a rise ratio of S/A = 17/29 cm.*

Overview of slope ratios ( after pith ration ) and tilt angles:
12,5/37,5 = 20°
15/33 = 24°
17/29 = 30° (optimum)
21/21 = 45°

(After DIN 18 065 A is max. 37cm and S has to have min. 14 cm)
The stair barrel length is min. 3 and max . 18 successive - steps; during long flights of stairs every 18 steps should be arranged an intermediate landing at the latest. The number of steps is resulting from the rise number, which in turn derives from the floor height and slope (rise number = H/S). For the determination of the steps 1 is subtracted from the previous result.
Based on the slope ratio the ideal slope number is for example in a house with a floor height of around
270 cm 16 rises , which results in 15 steps or stages. (*after Ernst Neufert „Bauentwurfslehre" 35. Auflage)
