Open staircases with central structure
Design Made in Italy
Rintal’s open staircases with central structure represent the perfect balance between Italian design, structural strength, and modularity.
Increasingly popular among those seeking an interior staircase that combines contemporary design, functionality, and a light visual impact, open staircases allow natural light to flow freely, helping to create brighter, airier, and more welcoming spaces.
Custom Solutions for Every Space
Each staircase is designed to adapt to different architectural settings, thanks to a wide range of modular widths (from 65 cm to 95 cm) and configurations (straight, with one turn, or with two turns). Whether for compact spaces or large open areas, these staircases become true focal points in any environment.
An Investment in Quality, Safety, and Durability
Prices vary depending on the materials, width, and selected options, but every Knock staircase is an investment in long-term quality and reliability. The structures are engineered to ensure comfort, safety, and lasting aesthetic value.
