High-strength, thermomechanically rolled ship plates are used for offshore applications.

Areas of application

The primary application is already in the name of shipbuilding steel: These steel grades are used for cabin structures on cruise ships. Particularly thin plates are used in large widths for such applications. These sheets exhibit best processing properties such as flatness and weldability. High-strength, thermomechanically rolled ship plates, on the other hand, are used in the offshore sector. They are used for deck superstructures on platforms or for special ships in the oil and gas industry.

Offshore

Whether in the Gulf of Mexico, in the North Sea or the Arctic, we deliver worldwide high-quality offshore structural steels according to offshore standards EN 10225 (including NORSOK) and API as well as to a variety of other international standards and specifications.

Offshore

Made for harshest conditions

Whether in the Gulf of Mexico, in the North Sea or the Arctic, our thermomechanically rolled structural steels for the offshore industry are used worldwide. We deliver high-quality offshore structural steels for fixed and floating offshore platforms according to offshore standards EN 10225 (including NORSOK) and API as well as to a variety of other international standards and specifications.

Offshore plates for oil & gas

Our offshore plates for the oil & gas industry are used worldwide under the harshest conditions. Living continuous development of new products to meet more stringent requirements, we are able to provide prequalified arctic steel for extremely low temperatures. Using toughcore® TMCP plates with extreme high toughness, you are able to increase the level of safety for your offshore structure up to 140 mm thickness.

High-quality plates for efficient electric power generation

Larger monopiles require higher unit weights in cylindrical and tapered pipe lengths. We achieve these weights by welding together two to three plates and call the new unit an XL plate. This highly efficient and innovative welding technique utilizes a four-wire submerged arc welding system capable of producing up to 60-ton unit weights.

These heavy units meet the growing requirements of offshore wind parks.

High-strength plates

As structures and machines become larger, the stresses in the components increase. High-strength steels with minimum yield strengths of 700 MPa or even higher up to 1100 MPa are capable of supporting these higher stresses and simultaneously lead to a decrease in the weight of structural members.

Thermomechanically rolled high-strength fine-grained steels combine excellent toughness with a very low carbon content and the low carbon equivalent and for an optimized weldability.

Shipbuilding steel plates

Our shipbuilding steel plates in normal and high-strength grades are used in offshore applications, platform superstructures and for special ships in the oil and gas industries, such as floating production storage and offloading vessels (FPSO) and even stainless steel clad plates for icebreakers.

We offer a wide range of dimensions and grades with best workability for ship manufacture, especially for welding: steel grades up to FH 36 and plates up to 140 mm thick and 3,950 mm wide. High-strength shipbuilding plates are certified e.g. by ABS in FQ70 up to 101.6 mm (4").

Our thermomechanically rolled steel grades are the key to efficient steel structures and provide potentially high savings in welding or maintenance.

Steel construction Industry

Customer-oriented partnerships and tailored solutions in the steel construction industry

Our thermomechanically rolled steel grades and weather-resistant structural steels set benchmarks with respect to their best processing properties and consistently high quality. They are the key to efficient steel structures and provide potentially high savings in welding and maintenance. Industryspecific material and manufacturing expertise, comprehensive preprocessing possibilities, reliability and relationships based on trust make us a trusted partner to the European steel construction industry.

We supply higher strength & lighter weight

alform® heavy plates find their applications wherever high workability and weldability coupled with high strength and weight savings are in demand. Utilization of the higher yield strength of high-strength fine-grained steels as opposed to conventional structural steels results in lower cross-sections. This leads on the one hand to cost savings in lower component weights as well as reduced expenditures for transports, assembly, foundations, component manufacturing, especially in welding as a result of minimized seam cross-sections.

Elimination of paint coating and maintenance

The alloying of small amounts of phosphorus, copper, nickel, chromium or molybdenum leads to the formation of a protective layer on weather-resistant steel outdoors. This layer protects the steel from further corrosion. Weather-resistant structural steels thus provide cost advantages as no anti-corrosion coating or maintenance required of the protective coating is required.
