Spiral Knock Design is the steel helical staircase that mixes great structural to freedom of customization of both finishes and accessories, signed by Giugiaro Architettura. Quality and versatility The structure of the helical staircase Spiral Knock Design is made of steel modules lacquered with epoxy paints which guarantee better resistance to wear and tear. The modules are interconnected via a patented anchoring system that provides greater strength compared to traditional prefabricated helical staircases. The adjustment of the rise can be done through a series of polycarbonate spacers which can be modulated according to the requirements, allowing Spiral Knock Design to adapt to any type of environment. The steps are made of solid finger joint beech wood. They are 4 cm thick and are connected to the structure using special supports. The handrail can be made both in solid beech wood, same finishing as the steps, or in stainless steel. There is also the possibility to choose among many models of railings for indoor stairs, of various colors and finishes, thus multiplying the possibilities to design a steel staircase that reflects your own style. Modularity evolves Thanks to Rintal Stair System, the innovative design system developed in collaboration with Giugiaro Architettura, it is possible to completely customize the look of the stairs by choosing accessories that push helical stairs beyond modularity, making them become real furnishing elements.
