About Kersten Group
The Kersten Group is an internationally active metal processor headquartered in Wanssum (Netherlands) with production sites in the Netherlands, Germany (Steißlingen), Poland (Kleszczów) and the United Arab Emirates (Ras Al Khaimah). The company manufactures curved components and structures from steel and aluminium, including offshore tubulars such as J-tubes, S-tubes and pile sleeves, curved profiles as well as custom components. The value chain includes bending over the X or Y axis, cutting, sawing, 5-axis machining, welding (SAW, GMAW/FCAW, GTAW, including heat treatment), construction and assembly as well as co-engineering. Customer industries include architecture, industrial plants, infrastructure, mechanical engineering, mobility and offshore; among other projects, supplies were delivered for the renovation of the PSV stadium. Quality management is certified to ISO 9001 and ISO 14001; welding work holds extensive qualifications to EN ISO 3834-2, DIN EN 15085-2, DIN 18.800-7 and AD 2000 HP0.
