Our History

In 1962 the brothers Franco and Giuseppe Rocca founded the “Officina meccanica fratelli Rocca
In 1976, the company abandoned the mechanical process, took the new name of DA-TOR and decided to invest in modern cold forming machines allowing a significant improvement in productivity levels.
The 90s are characterized by a constant evolution: increase in human resources, renewal and upgrading of machinery, technological investments in the production process, in the quality control and in the logistics.

New Millenium

The new millennium opens with a challenge: to manufacture and sell coupling nuts by cold forming. In those years, the company reached a staff of more than fifty units and grew quickly.

The plant of Beverate was then expanded and a new plant was founded in Calco (logistics and management headquarter). The Customers are now international and from all the industrial fields.In order to further improve the level of service, an additional investment was made: the logistics department of Calco was doubled. The company now occupies a total area of 20,000 square meters (10,000 of which are covered).
In 2011 after the death of both founders, the company is left in the capable hands of the sons. They believe and invest constantly in technological innovation and human resources in order to consolidate the company and to meet the ever-increasing demands of the market.
All these changes lead to the new goal reached in 2015 when the Company moves to the new production plant in Verderio with a covered surface of 12000 sqm, maintaining in any case the logistic site in Calco.
Today DA-TOR is a company of excellence in its field and has the privilege of working with the most important industrial groups in the world.
