Why extruded aluminum is synonymous with strength and lightness

Extruded aluminum is one of the most popular materials in architecture, industry, and design thanks to its combination of lightness and mechanical strength. In particular, the mechanical strength of extruded aluminum makes it an ideal solution for those seeking high-performance, reliable, and long-lasting profiles. At Sepal S.p.A., we understand the value of extruded aluminum and know how to transform its properties into high-performance, modern, and long-lasting solutions for our clients’ projects.

Extruded aluminum is now one of the most sought-after materials in the world of architecture, industry, and design thanks to its ability to combine mechanical strength, lightness, and versatility.

The lightness of aluminum: a tangible advantage for every sector

Aluminum weighs approximately one-third of steel, ensuring exceptional handling without sacrificing strength.

Reducing weight facilitates transportation, installation, and processing, while maintaining high structural efficiency.

This lightness is one of the main reasons why extruded profiles made by Sepal S.p.A. are used in:

  • Interior and exterior furniture and design
  • Windows, doors and curtain walls
  • Lighting and photovoltaics
  • Transportation and automotive
  • Technical components
  • Industrial applications

High Strength: The Potential of Extrusion

The true strength of extruded aluminum lies in its manufacturing process. During extrusion, the aluminum billet is heated to a high temperature and pushed through a die at very high pressures. This compresses and shapes the material, improving its internal structure and increasing its strength. The end result is a more compact, stable, and mechanically reliable profile. This process compresses the metal’s internal structure, reduces microporosity and internal cavities, uniforms the material composition throughout the profile, improves density, deflection, and stiffness, and ensures tight tolerances along with consistent quality.

Durability and corrosion resistance: a strength of aluminum

Aluminum is naturally resistant to corrosion, and the surface treatments available from Sepal S.p.A. further maximize its durability.

In particular:

  • Anodizing offers excellent protection and a uniform appearance
  • Powder coating ensures UV- and weather-resistant colors
  • Weather resistance makes the profiles ideal for outdoor use, facades, and exposed structures

Thanks to these certified treatments, extruded profiles maintain their structural and visual performance even after years.
