SUSTAINIBILITY REPORT

Our history

In 1976 Bernareggi started operating from a 100 square meters warehouse, supplying continuous cast-iron bars to customers in the surrounding area.

In 1976 Bernareggi started operating from a 100 square meters warehouse, supplying continuous cast-iron bars to customers in the surrounding area.
Since then, the acquisition of an ever increasing number of qualified customers had determined a balanced, steady growth engaged in a constant extension of storage space.

Today, with the acquisition of a new commercial area, the warehouse occupy a covered area of 5.600 square meters (the total warehouse is about 11.000 square meters) with a stock of more than 3.500 tonnes and a wide range machine tools.

Since 2010 BERNAREGGI has expanded its own range of products by introducing continuous and non-continuous casting bronze, supplied in bars, cut and semi-finished in all its forms and qualities.

 

In February 2021, the Danish Tasso foundry, a partner in Bernareggi for over 20 years, acquired the entire company, guaranteeing continuity in the casting business for the years to come.
