THE ART OF BENDING Punto Curvatura initial work was then made more important thanks to the introduction of a patent used for the bending or curving of the aluminum profiles. Punto Curvatura begins to curve for structural glazing systems, ventilated facades, curtain wall systems, and metallic sub-systems used for constructions. With the introduction of these technologies and the consequential word of mouth between extruders and customers, the reputation of Punto Curvatura begins to take hold in applications that differ from the building industry. From starting as a small center of research and development, the company now has an international customer portfolio.
