"Quality - Made in Germany" is what Hermann Rosorius Ingenieurbüro GmbH has been all about since its earliest days in 1949. The sophisticated range of external- and internal centring tools for welding technology in conduit-, system- and tank construction offers the user a quick, accurate and above all safe method for aligning pipes and flanges. Practical aids such as flange levels and tilt levels, centre punches or special models for orbital welding complete the product range.

In order to be prepared for the future requirements of a supplier to industry, Hermann Rosorius Ingenieurbüro GmbH has successfully obtained certification to ISO 19600:2016 and SA 8000:2014 as well as ISO 370001:2018 in 2022, in addition to ISO 9001:2015 and ISO 14001:2015.
