Progress from Tradition
Bochumer Eisenhütte Heintzmann is characterised 160 years of experience in mining.
Best known product is the TH support system invented by Heinrich Toussaint and Egmont Heintzmann. Being in use in mining and tunnelling since 1932 the TH support system is continuously improved.
Through a special process and the according equipment at our premises – both developed by Heintzmann engineers – mining support steel is being quenched and tempered in Bochum since 1955.
The outstanding quality of quenched and tempered TH profiles is among others the statically balanced resistance and the defined yield when used as yieldable support system.
