About ALU-ME
ALU-ME GmbH is a family business founded in 2000 in Karstädt in the Prignitz region, today run by the second generation of owners. On approximately 7,000 m² of production and warehouse space, the company manufactures components and welded assemblies from aluminium, stainless steel (V2A/V4A) and steel for industry and mechanical engineering with around 80 employees. The value chain ranges from design and development in 3D CAD to sheet metal working (laser and plasma cutting up to 2,000 × 6,000 mm, press brake bending at 320 t / 4.5 m), CNC machining, rolling and profile bending, welding (MAG, MIG, TIG, electrode, manual and robot-assisted) and surface finishing via regional partners. Quality assurance is carried out with a mobile optical 3D measuring system of the Keyence WM series for components up to 15 m. Customers come from commercial vehicles, mechanical and plant engineering, intralogistics, maritime cranes, the food industry, the construction industry and environmental technology. In 2025, ALU-ME was awarded as a Top 100 Innovator in Germany.
