GBM is a private Italian Company established by Giovanni Battista Martinis in 1962

Since its beginnings, GBM has been focusing on the design and fabrication of pressure vessels, starting from small carbon steel and stainless steel vessels, often produced in series (dampers, air & oil filters, LPG bottles for instance).

In 1970 GBM decided to increase its design office and to reorganize its workshop in order to produce heavier and more sophisticated pressure vessels, filters and heat exchangers, without loosing the attitude to be flexible and to remain competitive in the production of small vessels too, possibly in lots.
Specialisation’s and constant development’s processes continued throughout the years; GBM remains up to date with latest engineering software and fabrication technologies. Human resources and their excellence are GBM true winning factor.

The company owns its facilities, workshop and offices, for a total surface of approximately 20,500 square meter, of which 7,500 m² are covered area.

From its foundation, GBM’s core business consists of the design and fabrication of pressure vessels, starting from small carbon steel or stainless steel vessels, often produced in series.
