About Selig GmbH
Selig GmbH, based in Unlingen, has been manufacturing welded assemblies, steel and metal structures as well as laser-cut and press-braked sheet metal parts for over 40 years. Its range of services includes cutting by sawing, laser cutting and plasma cutting, press braking with bending lengths up to 4,250 mm, machining by CNC milling and drilling, and welding using TIG, MIG and MAG processes. A key focus is the processing of fine-grain structural steels, especially in MAG welding. Production covers both single-part and series production. After joining, the components are grit-blasted in-house, painted in the company's own paint booth and delivered via its own vehicle fleet. Weld seam inspection is carried out by the company's own welding engineer. As a certified welding specialist company (EN 1090-2 EXC3, DIN EN ISO 3834-2), the company primarily supplies heavy industry, mechanical engineering, crane manufacturing and manufacturers of agricultural and construction machinery.
