High-quality and efficiency
Aluminium offers many positive characteristics that guarantee optimal processing: Good weldability and formability, corrosion resistance and recyclability. It also reduces weight and offers unlimited customization, thereby facilitating the construction of high-quality and efficient ships and equipment components. At the same time, despite the weight savings, fatigue strength is not compromised - structures made from formed and welded semi-finished products exhibit exceptionally high rigidity. Our marine grade solutions are certified by the major ship classification societies and ensure high-quality, durable results at all times. Aluminium is increasingly used in an ever widening range of maritime applications as a result.
Use in recreational boats
Yachts and boats built with aluminium are lighter in weight, but also have high strength and can achieve high speeds. And thanks to aluminium, recreational boats also have a longer service life. And in the end of their lifecycle, they can be recycled – unlike plastic boats. That makes a valuable contribution to true sustainability.
Use in commercial shipping
The use of aluminium in commercial vessels also offers many advantages. Ferries, crew transfer vessels and cruise ships need to be as light as possible, fast and easy to maintain. And, if necessary, easy to repair. In addition, lightweight aluminium used in deck structures provides a better center of gravity and stability on the water.
Aluminium forms the future!
Our ambition is to sustainably reduce the ecological footprint.
Our vision – By providing high-quality, low-carbon products based on our first-class rolling and recycling capacities, we set the industry standard for sustainability.
Responsible procurement – We use metal from a variety of primary and recycled sources. Our metal management and procurement team focuses on the exceptionally low carbon footprint of metals.
Our future – We are continuously and significantly increasing our use of recycled materials. Our CO2 KPIs are monitored quarterly.
The result – We run an efficient operation with extremely low emissions and efficient consumption.
