Metallurgy

the bell was cast in žďas, a. s. in 2001.Making of bells belongs to the historical tradition of ferrous metalurgy in the Czech-Moravian Highland. On the occasion of the 60th anniversary of the commencement of production at ŽĎAS Metallurgical Plant, a carillon containing nine bells was cast.
 

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.

 

In 2009, the heaviest casting of the company´s history was cast in the foundry of ŽĎAS Metallurgical Plant. The tool carrier steel casting for an Italian customer weighed 45 540 kg after machining.
