Cut shapes

Bilderleiste

Our modern cut shapes facility harbors state-of-the-art plant systems, including 

  • plasma and oxy-gas cutting lines, 
  • a three-burner unit and  
  • a brand new chamfering robot. 

The various cutting technologies are perfectly adjusted to the thickness and grade of the starting material. The expertise of our employees guarantees excellent cutting quality and compliance with the narrowest tolerances. Their competence in combination with our modern mechanical equipment allows implementation of the most complex cut configurations. 

Post-treatment steps such as shot-blasting, annealing and straightening increase the product quality. Each of these processing steps is available to our customers on a commission basis.

Shipbuilding steel plates

Shipbuilding steel plates

Our shipbuilding steels in normal and high-strength grades are used in offshore applications, platform superstructures and for special ships in the oil and gas industry.

Areas of application

Steel shipbuilding plates are used in the cabin structures of cruise ships. The especially thin but wide plates are used for such applications to offer the best processing properties such as flatness and weldability. In contrast, high-strength, thermomechanically rolled shipbuilding plates are used in offshore applications. They are used for platform superstructures or for special ships in the oil and gas industry.

Safety and quality

We guarantee the highest safety and quality standards and meet all the requirements of renowned certification companies.

Thermomechanically rolled fine-grained structural steel plates

alform®-steels are thermomechanically rolled steels with excellent weldability, toughness and cold-forming behavior.

We supply thermomechanically rolled heavy plates made of fine-grained steels with minimum yield strengths ranging from 355 to 550 MPa with exceptional toughness and the best welding and forming properties.

As a special high-quality voestalpine grade, alform® steels are found in structural steel work, bridges, pressure pipes and in vehicle and crane manufacturing.

Our thermomechanically rolled fine-grained steels are characterized by a high degree of toughness and excellent weldability. The low degree of cold cracking and high degree of toughness in the welding seam lead to a high degree of safety in welded structures.

Utilization of the higher yield strength in the high-strength fine-grained steels (alform plate 420 M, 460M, 500 M und 550 M), as opposed to the conventional S355, results in thinner cross sections that lead to cost savings through light-weight components and thus to less expensive transportation, assembly and foundations. Savings are also achieved in component manufacturing, particularly in welding.

High-strength plates

High-strength plates made of fine-grained steel have a minimum yield strength of 620 and 700 MPa, and ultra-high-strength special grades achieve yield strengths of up to 1100 MPa.

Higher stresses

Machines and buildings are becoming ever larger. When you double the values of length, width and height of a component, the weight grows by a factor of 8, while the supporting cross-sectional area only grows by a factor of 4. This doubles the stress, which is calculated with the weight divided by the cross-sectional area. High-strength steels are capable of supporting these higher stresses and simultaneously lead to decreased weight of the component.

Specific advantages

The low weight of high-strength and ultra-high-strength heavy plates saves costs: The pre-material expenses, transport charges, and the assembly and foundation costs drop drastically. Add to that the costs saved during further processing of the material. Thanks to the excellent welding properties, work can proceed quickly and efficiently. On top of this, much less filler metal is required, and the weld seam test is simplified.

Our portfolio

We deliver high-strength heavy plates as fine-grained steels with a minimum yield strength of 620 and 700 MPa and ultra-high-strength heavy plates with a minimum yield strength of 900, 960 and 1100 MPa as special voestalpine grades.
