SIPRO® Stahl Holding AG

The operative business is managed by the sales companies. The mother company SIPRO® Siderprodukte AG and the other sales companies handle the distribution of a wide range of products from renowned, mainly Italian, steel producers.

  • Global trade transactions and transports are so complex that we have founded our own company for this purpose. SIPRO® International AG creates tailor-made import/export trade transactions, financing as well as transports for sea freight
  • The management companies operate with local staff in SIPRO’s main sales countries
  • SIPRO invests in strategic products through its associated companies. The latter give the Group broader business diversification, with further synergies for our services

VENETE Siderprodukte AG

Your sales partner for semi-finished products as well as bar steel for solid forming and bar steel for mechanical processing.

VENETE Siderprodukte AG is your specialist in Europe for VENETE products. How did this cooperation come up? A brief look at the history: The electrical steel manufacturer ACCIAIERIE VENETE S.p.A. has been producing commodity steel products since 1957: ingots, billets and reinforcing steel. At the beginning of the 1980s, the company decided to specialize in carbon steel products. As a result of this development, it is now one of Europe’s most renowned producers in the engineering steel sector. In the course of time, a significant amount of investment has been made in personnel, technology, the process and, of course, in the products in order to produce top grade, resilient quality steel. The company has also diversified and broadened its scope with the acquisition of additional production facilities in Sarezzo, Mura, Dolcè (IT) in 2003 and the steel mill in Borgo (IT) and the rolling mill in Odolo (IT) in 2018.

In 2003, the close cooperation between the Acciaierie Venete Group and SIPRO® STAHL SCHWEIZ was initiated. With the acquisition of the Lucchini plants in Northern Italy, the joint sales company VENETE Siderprodukte AG was established in 2006. Today, VENETE Siderprodukte AG is present in many European countries and is your contact for all issues relating to top quality steel products.

From us, you can purchase a variety of top quality products, including, for example, continuous castings (square and round), rolled rounds and billets, wire rod, sections, crude steel (round and square), and rolled flat and square steel.
