STAIR SYSTEM™ - Knock Design

Today we are proud to announce the launch of the new RINTAL STAIR SYSTEM, a revolutionary way of interpreting the idea of “Stair”, created by the collaboration between Rintal and Giugiaro Architettura (a prestigious and historic studio of industrial design).
The basic idea of the STAIR SYSTEM is that a stair is the result of the combination of several elements:
- Structure
- Steps
- Railing
- Handrail
- Accessories
Rintal and Giugiaro Architettura successfully created, for each of these elements, a set of innovative and unique components protected by European patent. New solutions, materials, shapes and colours to be matched and combined in time to create countless aesthetic solutions, according to the tastes and life style of the customer.
More than this! RINTAL STAIR SYSTEM presents itself as an “open system”, where customers’ choices are modifiable in time, so to offer the opportunity to create and recreate their own stairs e and quality of their own daily lives.

Structure in textured grey varnished steel with Unicolor UN 04
“Wave” decor, led lighting, wengé 23 steps, “Leaf” glossy
chromed railing by Giugiaro Architettura and wengé 23 handrail.
