Quarter-turn staircase with a central stringer (metal frame and wood steps)
KNOCK BASIC
RINTAL
Knock Basic is characterised by a high adaptability keeping always constant the harmony between the structures in varnished steel and the wooden steps.
The family feeling is common to all the solutions feasible with Rintal Stair SystemTM and therefore Knock Basic is the ideal contract staircase, because it can be modified at a later stage without any intervention on the opening.
