Metallurgy

Making of bells belongs to the historical tradition of ferrous metalurgy in the Czech-Moravian Highland. A cast steel bell weighing 530 kgs has been cast on the occasion of the 50th anniversary of the beginning of operation of the Metallurgical Plant of ZDAS Company.

In the summer of 2002 the clapper of the biggest Czech bell, located in the St. Vitus Cathedral in Prague, cracked. A new clapper has been made in the modern forging shop of ZDAS Company according to the 300 year old model, which has been presented to the Prague Castle Administration as a gift of the management of ZDAS joint-stock company.
