Overview
About Steffenini S.R.L.
Who we are
STEFFENINI srl was founded in 1967 as a generic laboratory with the name of OMS Officina Meccanica Steffenini under the guidance of Francesco, the founding father, who is dedicated to the growth and development of the company. Francesco's son, Paolo, followed the same track drawn by his father. Thanks to his skills and dedication that he has always shown towards work, he embarks on a new path at the beginning of 2000 with the name of STEFFENINI VALVES by moving his activities to other markets such as petrochemical, energy and mechanical, developing his skills in production of industrial pumps, flanges and valve components by including design and production of own valves. At the end of 2018, their son Cristian is added to the company and together they decide to focus on what has always been our core business, the subcontracting, dividing the VALVE CONSTRUCTION and THIRD PARTY PROCESSING activities into two departments so the company name becomes STEFFENINI srl. The continuous efforts, the search for qualified personnel, the alternation of old structures with increasingly advanced machines, the passion that involves all the staff and the natural vocation that drives them to lavish all their energy, taste, pride in Seeing your company thrive, gain credit and inspire customer confidence is the company's mission. Specialized above all in the machining of valve components, they are skilled and equipped also for particular machining starting from ø 50 up to ø 2000
