Hydraulic steelwork

The steel construction workshop (formerly Hecker Bau) exists since the mid-1960s and is certified according to EN 1090-2 to EXC3 for work in steel and steel hydraulic engineering.

The steel construction workshop is equipped with a flame-cutting machine from MicroStep. This enables Hecker to cut steel sheets with a maximum surface area of 6.0 m x 2.0 m and a thickness of 5 - 25 mm with plasma and 8 - 150 mm with oxyfuel. Only a drawing in DXF format is sufficient to generate a flame cut. Mr. Kropp can accept firing orders by calling +49 4481-928823.
