Aluminium sheets and coils for building applications

More info Close

Our product range includes aluminium coils and sheets with plain or treated surfaces, anodized or anodizing-quality sheets and coils through our premium product line Laminium®, and technical paint stock.

International Standards, European and National building regulations are becoming tougher by the day, with the aim of increasing the air tightness of buildings, and thereby minimising heat losses. Aluminium products are ideal, as they are not porous and their mechanical stability secures the highest performance throughout the years.

Our aluminum solutions have the option of bright, textured, brushed, anodized and mill finishes and various surface treatments. Our products are decorative, durable and corrosion-resistant. They offer excellent insulating properties and formability and have a good strength-weight ratio. At a time when sustainability is of primary concern, we work to ensure our aluminium solutions support renewable energy and low-consumption housing, leaving minimal environmental impact.

Aluminium extrusion solutions

More info Close

The building market now accounts for a significant part of soft‑alloy extrusion consumption in Europe. The major applications for aluminium extrusions in building construction are windows, doors and curtain wall systems. Other applications include scaffolding and form works, building interiors (shower stalls, furniture, stairs, elevators, lighting, railings, etc.), and building exteriors (steps and planks, dam logs, roller shutters, sun louvers, swimming pool equipment, garden furniture, etc.).

Our extrusion plants offer a wide range of products and services to customers in the building and construction sector. These include soft alloyed extrusions, tubes and bars further enhanced by surface treatment (clear and color) and thermal breaks. In addition, we provide solutions for machining, bending and cutting to length as well as for marking, shrink‑wrapping and tracking.


Aluminium extrusion solutions for steps and planks
