Our Story

To talk about locks for wooden doors means first stepping back in time as far as 1830 when Giuseppe & F.lli Bonaiti was founded, to the era when small Lecco area workshops produced the base metal used to create a series of components.
Our workshop gradually increased in size and alongside the fastenings and spring catches we also find bed warmers, chestnut roasting ovens, bed bases and the tubing used for headboards, until 1936 when we began to produce external application door locks.
At the beginning of the war we created a lock model fitted into the front of the door, an absolute novelty in those days, based on the British models patented at that time: hence the term “patented” which went on to become an everyday term to identify this type of lock.
At the beginning of year 2000, in the same factory situated in Calolziocorte, Bonaiti Serrature started to produce magnetic locks which are the result of many years of research and development.

Our Values

Technology, production and italian design

Passion for research and innovation
Bonaiti's planning philosophy has always been to anticipate the different market needs, offering original and innovative technical solutions since the beginning of its history. From sliding door closing systems, the absolute novelty in the nineties for the Italian market, it passed to locks powered by magnetic fields generated by permanent magnets, but Bonaiti is already thinking about tomorrow's products.

Our logo

The logo states, from one side, the strong roots in the Lecco industrial area with the stylization of the shape of Como Lake, and at the same time, the logo characterized Bonaiti's production at the beginning of the internationalization process because the recall to the giraffe helped creating a brand to connect to the company and to support the significant sales flow on the African continent.

Bonaiti Serrature evolution from a business and organizational point of view has favored the development of a modern company, in which, alongside the traditional activity of locks manufacturing, the activities of research and development, communication, technological innovation and after-sales service have equally developed. All this is summed up in the company's new payoff: much more than locks.

In the departments, about 70 employees produce 15.000 locks every day on 12 automatic lines. The use of non-polluting materials and the environmentally-friendly working cycle allow the Company to be recognized as an environmentally friendly company.


Bonaiti’s design philosophy has always anticipated all needs of the market, proposing original and innovative technical solutions and ensuring the highest quality of the product. This entailed a very high annual investment in relation to turnover, creating a technical team of recognized professionalism and experience.

Sophisticated IT systems allow technicians to follow every project from the beginning, up to functional tests. The test cabin looks over the operation of each lock, simulating realistic opening / closing cycles of the locks.


Research and technological development has allowed the Company to offer a complete range of products.

Thus the magnetic lock was invented, which employs an operating system entrusted to magnetic fields generated by Permanent Magnets existing in nature. The use of alternative materials to the iron, allows the silent operation. The adoption of magnetism significantly improves aesthetics and functionality.

The overall effects on the structure of the lock are obvious: a clean design that integrates with the new lines of doors. From the first model, B-ONE has progressively progressed over time to realize the B-TWO, followed by the exclusive B-FOUR, also entering the glass door sector with the B-ALEX and B-FIVE. The magnetism has also allowed to produce a lock without handle, the B NO-HA, allowing therefore to have doors without interruption of the formal architectural lines.


From the widespread presence in every Italian region with the sales network of agents that reach both door manufacturers and hardware dealers, Bonaiti has passed over time to directly and indirectly distribute catalog products abroad.

Thanks to the quality of the product and the evolution of the technologies, with the Bonaiti magnetic locks, from Lake Como, it has entered the global market, conquering and managing many Countries all over the world.
