Knock Design is a  modular design staircase  that combines great flexibility of composition with structural solidity, aesthetic customization and a strong design content.

The extreme design flexibility makes Knock Design the perfect solution also for construction companies, leaving the freedom to customers to customize their staircase according to their tastes and housing needs, without subsequent masonry interventions.

The  self-supporting structure  is made up of  painted iron modules  connected by a patented fastening system which offers considerable strength, compared to classic  prefabricated stairs . The adjustment takes place via polycarbonate spacers that allow Knock Design to adapt to all spaces, even the most critical ones, in a simple and precise way. The steps are in solid finger joint beech wood, 4 cm thick, connected to the structure by means of supports. The handrail is in solid wood matching the steps or in   painted or stainless steel .

Rintal Stair System for total customization

Knock Design is a  self-supporting staircase  designed to allow maximum freedom of aesthetic customization. The underlying philosophy is that of the system (Rintal Stair System) which revolutionizes the concept of  prefabricated internal stairs  by transforming them into an open combination of elements, each of which can be customised, combined and re-combined to create a unique solution.
With the Rintal Stair System, the structure, steps, handrail and accessories are no longer just parts of the staircase, but become tools for creating a composition that fully reflects your style. Many wood and metal colors available, the possibility of choosing from 10 different models of railings for internal stairs, the LED light integrated in the structure, two different models of masks and the decorations of the structure multiply the possibilities to infinity. In addition, it will be possible to continue to modify one's scale even over time.
