What are standard steel staircase dimensions?
Our base configurations are a 1000 mm wide straight staircase with 12 steps for a 3250 mm rise over a 3960 mm run, and a 1700 mm diameter spiral staircase with 18 steps for a 3330 mm rise. We make straight staircases from 800 mm to 1200 mm wide and more. Every staircase is recalculated for your floor-to-floor height so all steps have an equal rise and the climb is comfortable.
