Steel and stainless steel foundry

As a steel and stainless steel form foundry with a very broad material range, we offer you the possibility of manufacturing your cast parts from numerous unalloyed, low-alloyed and high-alloyed materials of 0.5 kg up to over 4000 kg unit weight under one roof.

These products are used on the high seas under large loads, in the safety centres of nuclear and conventional power plants, in the petro chemistry sector, on ships or in the oil production worldwide – everywhere where the highest safety is needed, Geweke quality casting is in demand and in use.
