BRUNO E MARIO TREZZI SRL was founded in 1961 just outside Milan.
The main activity consisted in the recovery and sale of refractory materials
In the early 1970s the owners saw a new market prospect in the marketing of high quality carbon products.
He therefore decided to specialize in the processing and distribution of refuels with a high carbon content, ferroalloys and graphite electrodes used mainly in the steel, aluminium, chemical and brake sectors.
The graphite and all its derivatives become the core business of the company: and it is from here that the change of company name to GRAFITREZZI SRL takes inspiration and it took place in October 2022.
