Simple sheet pile walls, combined walls or large-pipe-dolphins – USM delivers individually, flexibly and reliably in accordance with our customers’ requests and the prevailing conditions.

The logistical capabilities and production possibilities at the Bremerhaven site of Unterweser Stahl- und Maschinenbau GmbH are unmatched.

Pier cranes, portal cranes, giant forklifts, production-, blast and corrosion protection halls as well as outside storage facilities are available for these tasks.

In addition to hydraulic steel construction, the fitter’s shop, general and heavy steel construction, the construction of machinery and industrial plants and ships repairs are central areas of the work performed by USM GmbH.
