About Tresoldi&Casiraghi Srl
Who we are
For Tresoldi & Casiraghi, producing quality is more than a mission; it has always been a true passion. Since 1962, the year the company was founded, this passion has been reflected in the production of carpentry, which over time has won recognition on the Italian and international markets. A way of working that marked the transition from the craft dimension to the industrial and technological dimension in order to ensure competitiveness and offer only the best at always competitive prices. Progress has been made not only in terms of the number but also in terms of the security of internal processes and respect for the external environment. A success that is thanks to the daily commitment of a group of people who are able to look at the challenges of the future with the same enthusiasm as on the first day. The company employs personnel who specialize in welding, bending, stamping and assembly. The welding work is carried out by qualified personnel who have the following qualifications: WIG — MIG — MAG — ELECTRODE. We are also able to issue mechanical test certificates and non-destructive test certificates.
