Profile technology from idea to series production
The Bültmann Group consists of four companies – Kronenberg Profil, BKB Profiltechnik, Springob Profil and Bertrams Profil – with around 250 employees at two locations in Sundern-Amecke and Leichlingen. The group manufactures individual profiles and profile systems, including complex cross-sections with integrated machining, cross-section-modified profiles, laser-welded profiles, bent profiles as well as DIN standard profiles with individual fixed lengths and hole patterns. A total of 32 modern roll forming lines are available on 35,000 m² of production and storage space. Both locations have in-house development/design and their own toolmaking. The products are used, among others, in the automotive industry, electrical engineering, air conditioning technology, the lighting industry and renewable energies.
