About us

A family business founded in 1933, with values spanning back over 3 generations

Head of the company "Constructions Mécaniques A. Borrelly" from 1933 to 1968

Borrelly®, in search of innovation for 3 generations

It all started in Lyon in 1933, in a Mechanics workshop. Alexandre Borrelly was a passionate, rigorous and ingenious mechanic

His son Albert, just as inventive, took over the reins in July 1968, his focus, from the 70s onwards, was on the design and manufacturing of spring washers.

Driven by the same passion as his father, he grew Borrelly® into a firm appreciated for its technical know-how and expertise. Over the years, Borrelly became a reference and brand of choice for engineers working in the mechanical industry.
