About us

from 1962

To manufacture quality has always been more than a mission for Tresoldi&Casiraghi, it has always been an actual passion. Since 1962, when the company was set up, this passion has been implemented in the manufacture of carpentry which, over time, has distinguished itself on the Italian and international market. A way to work which marked the step from the artisanship to industry and technology to ensure competitiveness and offer only the best, along with competitive prices.
A progress made not only by figures but also in term of safety of internal processes and compliance with environmental regulations. A success built day by day thanks to the commitment of a group of people capable to face the challenges of the future with the same unchanged enthusiasm of the beginning.
