Painting / preserving

SMHZ Stahl- und Metallbau Harz GmbH has a steel-shot blasting plant with an adjoining, heated paint booth (dimensions LxWxH 18 x 9 x 5 m), in which modules with a unit weight of up to 40 tonnes can be preserved. Our specially trained and qualified employees are capable of dealing with very diverse customer requirements.

We offer anyone interested the chance to have sand-blasting and preservation work done by our employees.
