materials
We work with these materials, according to German DIN-Norms.
We are also able to translate from British Standards and US-Standards to European Norms EN and to DIN:
sheet metal, solid shafts, profiles, semi-finished standards, blocks and slabs:
- all kinds of flame-cuts: we work with flame-cuts up to 400 mm thickness, typically 1.0553 (S355, St 52), 1.7131 (16MnCr5)
- custom-rolled sheet metal: widths up to 4 m and custom-specific heats
- boiler-plate, manganese-plate, Hardox-plate (Swedish Steel), structural plate, increased temperature steels
- all kinds of steel profiles and rectangular tubes: we cut semi-finished products up to 700 mm in-house
- warm- and cold-drawn profiles (EN 10277), cold-drawn guiderails, cold-drawn standards
- hollow round tubes up to D = 2500 mm

- steel for flame- and induction hardening, typically: 1.1213, 1.3505
- spring steel (2000 N/mm2)
- piston rod material, chromed and ground
castings:
- all kinds of castings: steel iron, ductile iron (nodular), grey iron, precision castings, aluminium castings, bronze castings, brass castings
- especially ductile iron (GGG, GJS), up to GJS-700, up to 13 tons weight per part
- high-pressure ductile iron up to 600 N/mm2 and elongation of 15% (GJS only 7%), pressure-tight ductile iron
- ADI-castings with 1000 N/mm2
- hollow round tubes up to D = 1500mm: ductile iron (nodular), grey iron
- cast blocks up to 3000 mm: ductile iron (nodular), grey iron
- castings from wooden or plastic patterns, investment castings out of polystyrene (Styropor)
non-ferrous metals:
- all kinds of aluminium-alloys; especially aircraft-aluminium with 600 N/mm2
