J.Christof now looks back at a long history.
More than 50 years ago, veteran Styrian businessman, Johann Christof Sr., founded the company, IRB Idustrie-Rohrbau.
Thanks to smart investments, farsighted decisions, and strategic acquisitions, this developed into a global corporate group, the Christof Group. In 2018, the owners decided to focus on the competencies of their companies.
The specialists for plant construction and high-quality industrial services were bundled into J.Christof. This is how the range of services of this group can be expanded and their global lead position broadened.
