Nowadays plants in different sectors,
must work under very critical conditions, therefore high temperature and corrosion resistant materials are increasingly employed.
The flexibility of our manufacturing systems,
allows us to offer standard and out of standards products even for limited request
and for quick delivery.
We export our production all over the world and supply both retailers and end users. The main users of our products are the chemical, petrochemical, pharmaceutical, oil & gas, off-shore, seawater desalination, nuclear and power generation industries.
Our mission is to manufacture pipes, fittings and prefabrications in
special alloys, standard or customized,
of high quality, on time and with the characteristics defined in the

"Continue to value the experienced
HR and continue
to invest in their training."
Thanks to the flexibility of the production system and thanks to the stock of raw materials and finished products, a wide variety of requests can be satisfied such as non-standard dimensions, production of small batches, manufacturing in a very short time.
The materials treated are all metal alloys with exceptional resistance to corrosion and high temperatures.

The constant growth in terms of turnover, collaborators and square footage of the plant is the confirmation of the virtuous path followed since the beginning.
Our history, since 1954, has been marked by constant growth and specialization in the machining and welding of special materials which have allowed us to export our products all over the world.
The company culture has remained anchored to the same values
that have determined its success, year after year,
even when people, markets and situations have changed.

Exports are affirming, with requests
in particular from chemical,
petrochemical and pharmaceutical,
European and non-European industries.
The customization, upon request,
of the products remains a strong point.
The use of materials such as titanium, Duplex, Superduplex and Super-austenitic stainless steels increases the
turnover which extends to the off-shore and Oil & Gas sectors.
