Granziero S.p.a. was founded by Mr. Otello Granziero in 1974.
This courageous choice came from the experience gained as an employee for over ten years in an important company of metalworking carpentry and boiler making in Padua, Italy.
From the profession of carpenter, he obtained a high degree of specialization in the construction of pressure vessels, mainly intended for water treatment.
On the 2nd of January 1974, the activity of “Granziero Officine Metallurgiche” (Granziero Metallurgical Workshop) officially began, and thanks to the support and dedication received from the closest collaborators of Mr. Granziero, the company immediately studied the technical and constructive aspects to acquire the necessary knowledge to build process columns, process reactors and pressure equipment for the petrochemical sector, oil refineries, oil & gas.
Over the years, the company has acquired a great experience in the construction of pressure equipment, specializing in the manufacture of columns and process reactors. The most used materials are: Carbon steel, High strength carbon steel, Stainless steel (type 304, 304H, 310S, 316, 316H, 316L, 321, 410), Low alloy steel, cladded steel.
A new furnace for PWHT, HDO & ISR completely designed & fabricated by Granziero has been installed.
