Our Story

A story that starts from afar

The original nucleus of Cortellezzi Primo was opened by its founder, Cortellezzi Primo, towards the end of 1955, who had accrued considerable experience and skills working in large companies in the mechanics sector. In the early sixties the first product that increased the company’s notoriety was marketed. In fact, it was on the occasion of the Rome Olympics that a system was developed to block telephone dials in order to prevent international calls.

Primo’s son Franco joined the company in the early ‘70s, managed to establish collaborative projects with several Italian and foreign companies in need of ‘special’ or personalized cylinders that were hard to find elsewhere on the market. The company went through a tumultuous period of change during the ‘80s. In fact, in those years the company changed its form of incorporation, becoming Cortellezzi Primo & C S.r.l., but remained in the hands of the family. Also during that time, the company began producing a very special line of gate chains, which became very popular and increased the company’s visibility with the public at large.

In the new millennium, when Primo’s grandson Fabio joined the company, new locks were designed in collaboration with partners in the nautical and automotive sectors. In fact, these two sectors often have very special requirements that present stimulating challenges. Starting in 2010, some collaborations and partnerships were set up with established clients, permitting the development of a special catalogue of accessories for wood, glass and aluminum products.
