Modular spiral staircase made of engineering plastics launched

Fontanot, an Italian leading company engaged in the production of open staircases, recently introduced a modular outdoor and indoor spiral staircase entirely made of technopolymers. Robust and conceptually modern, the product was launched thanks to the expertise of Fontanot’s R&D center in collaboration with Fauciglietti Engineering and LATI. 

The Techne staircase, included in the 2008 edition of the ADI design index, and protected by an international patent, is available in 120, 140, and 160 cm diameters, and is made of independent steps easily connected to each other in the bearing hub. It is equipped with different railings, and available in green, red and white.  

The development of the steps required intense planning, calculation, and selection of materials, in which LATI took part with through its own Technical Assistance and Co-design structure. In fact, in order to comply with the strict regulations, it was necessary to fine-tune the tread and hub design by introducing not only duly positioned and dimensioned reinforcing ribs, but also different materials with their own features contributing to achieve the best synergy between stiffness, robustness, and weight. 

Once the project was defined, the molding process was then optimized based on a large geometry, and LATI contributed to this activity with its great experience in the field of conversion. The step resulting from this combination of skills consists of a superstructural core made of PA66 stiffened by a high content of special glass fibers  (hub and ribs area), and a highly reinforced, dimensionally stable PP overmolded tread resistant to UV and weathering. 

Due to its excellent mechanical resistance and lightness, as well as its aesthetically pleasing appearance despite the high reinforcing fiber content, the modular element of the Techne staircase lends itself to indoor and outdoor applications in both domestic and industrial environment.
