New shipbuilding steels for new challenges

For decades, our quarto plates have been successfully used as base material to build dozens of ships: from small vessels to the world’s largest cruise ship ever built – Harmony of the Seas.

The reliability and superior quality of our quarto plates offer improved strength, workability, and weldability. They are certified by all major certification bodies and can withstand even low temperatures which makes them suitable for many arctic and deep-sea vessels.

Our steel plates can be supplied as-rolled, thermomechanically rolled or normalised, shot-blasted/painted and/or cut and bevelled on demand. They are now also available in a wider dimensional range and at weights up to 18-19T.

Tailored service

ArcelorMittal’s high quality, innovative solutions and exceptional service performance are helping shipbuilders to go beyond their objectives.

Our global footprint ensures we can assist customers technically and commercially, wherever they are located.

ArcelorMittal is involved in multiple research programs to improve the steel used in shipbuilding, and to create new solutions. Through co-engineering projects, we collaborate with the main actors in the shipbuilding industry to identify solutions which offer better performance and significant savings.
