The company Stahlbau Ulrich Schäfer GmbH & Co. KG is a medium-sized family owned company,
which is now successfully working as a steel construction company for more than 30 years.
The company was founded by Ulrich Schäfer and is now managed by Reinhard Schäfer.
Our focus is on the production of accessories for wind energy and for the offshore sector, in the marine cable installation and in the manufacture of own offshore containers. Since 2013, we have our own offshore staff and therefore we offer offshore services.
We are certified according to EN 1090-EXC 3 and also according to ISO 9001.
In the field of wind energy we include various reputable companies among our customers,
whom we supply with special lifting equipment, transport racks, assembly tools and storage racks.
For the offshore industry, we deliver according to customer requirements customized products,
from lifting equipment certified according to DNV 2:22, going over to the production of Sea Fastenings incl. Mobilization of entire ships,
to the construction of own offshore framework and Offshore Containers according to DNV 2.7-1 with lifting means,
for example, according to DNV 2.7-1, DNV 2.7-2 or DNV 2.7-3.
We’ve entered the market in the offshore sector in the 90’ss through the submarine cable laying.
At the time we built the first submarine cables for Siemens. Soon after,
followed the first device for the injection of submarine cables in the sea floor.
Later in 90’s Siemens sold the submarine cable laying to the Norddeutsche Seekabelwerke,
for which we are still working today. Our product range includes cable trays, sea cable tanks,
roll sheets (powered and unpowered), jet plough (blades), lifting equipment, cable slides, pulleys or entry funnels.
In 2007, we built one of the first pure Offshore Container in Germany according to DIN EN 12079 / DNV 2.7-1 together with the Germanischer Lloyd. Since then, we rebuilt each year about 20 containers to we have built them new.
These are often cargo containers, but also one or two Offshore Container constructions.
Of course, we manufacture not only for the industry but we also serve customers in the local environment, for example, stairs, railings, fences, balconies, etc.
We limited not only to steel processing, but also for aluminum and stainless steel.
In a special planned hall, the material is stored and processed. For processing we have trained staff that has valid
welding tests for the welding processes 141 (WIG) and 131 (MIG).
Of course the welds are stained and polished after welding by us.
