About AL Metalltechnik
AL Metalltechnik is a metalworking service provider based in Ahaus-Alstätte in the Münsterland region and has been on the market for more than 20 years. The company supports customers along the entire value chain: manufacturing with modern robotic welding systems (MAG) and manual welding stations (MIG/MAG), CNC technology for milling, bending and sawing, finishing through blasting, edge rounding, wet painting and powder coating, through to warehousing, logistics and just-in-time delivery. Assemblies up to 15 m in length and 65 t in weight are fabricated by manual welding; the robot fleet includes, among others, a 30-meter gantry system for parts up to 3000 kg. In-house mixing plants enable the production of heavy concrete (up to 10 t per batch, with steel scrap addition) for radiation shielding applications and crane counterweights. Core industries are rail and rail transport, radiation shielding and crane construction; the company is certified, among others, to DIN EN 15085.
