About Markgraf Schweissfachbetrieb GmbH
Markgraf Schweissfachbetrieb GmbH is a welding specialist company founded in 2003, certified by SLV Munich, based in Aichach-Walchshofen (Bavaria). The company carries out contract welding work in the field of civil engineering, including installation and removal of Larsen strutting, Larsen double strutting and double-U strutting, assembly and disassembly of hydraulic systems (groundforce) as well as beam and pipe bracing. Further services include stud welding (Boltec) up to 22 mm diameter, flame cutting (lance cutting) and the manufacture of steel structures in execution classes EXC2 and EXC3 according to EN 1090-2. Steels of grades S 235 and S 355 up to material thickness 30 mm are welded using the MAG (135, 136) and manual metal arc (111) processes according to DIN 18800-7 Class C. References include major special civil engineering and construction companies such as Bauer Spezialtiefbau, Züblin, Strabag Spezialtiefbau and Porr Spezialtiefbau; completed projects include, among others, Stuttgart Airport and construction projects in Munich and Frankfurt.
