LEM history: since 1974, a journey of innovation and craftsmanship
LEM
Since 1974, we have firmly believed in the potential of people and in the protection of craftsmanship applied to the industrial process, focusing on the quality of Made in Italy and technological progress.
A 50-year-long story of passion
LEM was founded in 1974 in the heart of Valdarno, from the vision and determination of Dino Franco Gualdani and Franco Rosadini. With a long artisanal tradition behind them and a spirit turned to the future, Gualdani knew how to transform an ambitious project into an industrial reality capable of becoming a benchmark for galvanic and PVD treatments applied to fashion and luxury accessories.
From the beginning, LEM has embraced a philosophy that combines artisanal attention to detail with the adoption of innovative technologies. This unique combination has allowed the company to grow rapidly and win the trust of major brands in the fashion and luxury sector, becoming synonymous with quality and reliability.
Dino Franco Gualdani was a forerunner for his time: he decided to bet on his territory and believed in the possibility of innovating and staying one step ahead.

LEM: Innovation and Tradition at the Service of the Future
Since its inception in 1974, LEM has never stopped evolving and looking towards the future. It equipped itself with an in-house chemical laboratory for immediate improvement of processes and, a few years later, anticipated industry trends by choosing to invest in physical vapor deposition (PVD) treatments, which at the time were still seldom used in the treatment of luxury metal accessories.
Upon reaching its fiftieth year, LEM can boast one of the largest automatic galvanic plants for accessories in Europe, a state-of-the-art manual galvanic facility, and a dedicated team focusing on ESG issues.
