Clad plates

Roll-bonded clad plates are the economic alternative to expensive high-alloy and non-clad plates. The mechanical properties of the base material are optimally combined with the corrosion resistance of the cladding material.

Clad plates

Our roll-bonded clad plates and heads are found in chemical equipment applications and refineries, in the oil and gas industry, coke drums and the food industry. Clad plates are also used in seawater desalination and flue gas desulfurization plants.


Clad plates consist of a base and a cladding material.

The base materials for our clad plates are produced exclusively in our own steelmaking plant in Linz. Cladding materials are purchased in the form of slabs and sheets from renowned manufacturers.

The base materials are predominantly made of structural steels, steels for boilers and pressure vessels and fine-grained structural steels, all of which are characterized by good weldability and formability.

Cladding materials are made of ferritic and austenitic stainless steels, nickel and nickel-based alloys, copper and copper-nickel alloys, all of which have excellent anti-corrosive properties.

Further material details are contained in the brochure that you can open below.

The base material surfaces are generally delivered in as-rolled or shot-blasted condition.

In almost all instances, the surface of the cladding material is polished. Our standard polish is 80 grain. Other grain sizes are available upon request.

Here you will find more information about delivery conditions and certifications for clad plates.

Clad linepipe plates

Sour-gas-resistant linepipe plates

The sour gases occurring in the linepipes used for the transport of oil and gas are highly corrosive. Only the highest-quality materials are capable of withstanding this aggressive medium. As a leading provider of sour-gas-resistant linepipe plates worldwide, we supply linepipes with corrosion-resistant cladding for specific applications.

Protective cladding material

The base material is decisive in the production of linepipes. Our roll-bonded clad plates are extremely strong, tough and resistant to corrosion as a result of their cladding material. Materials such as our X65 product with nickel-based alloy 625 provide the optimum physical properties. Our pipe partners process these materials into metallurgically bonded clad linepipes.

Elements of the highest quality

The metallurgical bonding of the clad linepipes withstands the highest mechanical stress and dynamic loads, making the pipes especially suited to deep-sea applications under highly corrosive conditions.

Reeling and riser pipes 

  • Roll-bonded clad plates for pipelines 
  • High degree of corrosion resistance, even in sour-gas applications 
  • More efficient and cost-effective reeling of pipelines than with on-board welding 
  • Roll-bonded clad plates (SCR) for vertical pipelines (risers) 
  • Excellent properties of metallurgical bonded clad plates for highest degree of compression strength

Linepipe plates

Specialist for extreme conditions

Extremely low arctic temperatures, extreme pressures in the deep ocean, acid media: Even the most difficult conditions have no negative effect on our linepipe plates. Our plates are found in depths of up to 3,000 meters below the sea surface, either in the form of sour-gas-resistant linepipe plates or as land lines up to 48 inches (1,220 mm) in diameter. We also offer roll-bonded clad linepipe plates with a corrosion-resistant cladding for the highest demands in sour-gas application. As a specialist in modern thermomechanical rolling technology with accelerated cooling, we are among the world's industry leaders. More than two million tons of sour-gas-resistant linepipe plates and high-toughness linepipe plates for thick-walled deep-sea lines testify to the success of our high-quality products.
