Steel Division
Our roll-bonded plates and heads are used in chemical apparatus engineering and refineries, in the oil and gas industry, in oil sand processing (coke drums) and in the food industry. Clad plates are used in seawater desalination and flue gas desulfurization systems.
A roll-clad sheet or plate consists of a base and a coating layer material.
The base materials for our clad plates come 100% from our own steel production in Linz. Cladding materials are purchased in the form of slabs and plates from renowned manufacturers.
The base materials used are primarily structural steels, boiler and pressure vessel steels and fine-grained structural steels that are characterized by good weldability and workability.
As cladding materials, we supply ferritic and austenitic stainless steels, nickel and nickel-based alloys, copper and copper-nickel alloys that are characterized by their respective corrosion properties.
Further details can be found in the brochure linked below.
The surfaces of the base materials are usually supplied in as-rolled condition or are sandblasted.
The surface of the cladding material is usually ground. We supply ground with grain 80 as a standard. Further grindings can be supplied upon request.
Here you will find more detailed information about delivery conditions and certifications for clad plates.

The metallurgical bond between the base material and the cladding material in our clad products is formed under high pressure and high temperature during the hot rolling process.
The result: outstanding shear strength that significantly exceeds the required standard value. In practice, it approximately corresponds to the yield strength of the weaker material – clear evidence of the exceptional bonding quality and, consequently, the reliability of our products.
The perfect bonding interface prevents delamination even at the tightest bending radii – ensuring maximum forming reliability, even under demanding conditions.
The bonding interface is free from diffusion and so-called hard spots (localized hardenings), which guarantees consistently high shear strength.
The bonding interface is free from diffusion and so-called hard spots (localized hardenings), which guarantees consistently high shear strength.
Optimized heat treatment and PWHT (Post Weld Heat Treatment) parameters ensure excellent corrosion resistance. The NACT process prevents sensitization, thereby maintaining a consistently high level of corrosion resistance over time.
For alloys such as Alloy 825 (UNS N08825), this resistance is specifically preserved through a stabilizing annealing process followed by water quenching.
An additional tempering step ensures good impact toughness as well as the required strength.
The low carbon equivalent value of our roll-clad plates ensures good weldability and minimal hardening in the heat-affected zone.
Clad plates and heads from a single source. Supplying clad plates and heads through one central partner simplifies procurement, reduces interfaces, and saves both time and costs. Our “one-stop-shop” approach ensures a streamlined supply chain, high planning reliability, and maximum efficiency throughout your project workflow.
As the first and so far only supplier, we provide Environmental Product Declarations (EPDs) for roll-clad plates.
This creates transparency and supports sustainable procurement decisions. With our CO₂-optimized greentec steel variants, we offer an additional way to significantly reduce the environmental footprint of your products.
Not only can material costs be reduced, but the use of clad materials also lowers expenses for welding consumables.
The thicker the base material, the lower the overall costs – all while maintaining consistently high corrosion resistance.
Long-standing partnerships and consistently positive customer feedback show: trust is built where performance meets expectations.
With an on-time delivery and production rate of over 95%, we stand for reliability our customers around the world count on – day in, day out.
