Aluminum sheets are among the most versatile materials in modern industry due to their low specific gravity (about 2.7 g/cm³), exceptional resistance to corrosion and excellent machinability. Thanks to the natural oxide layer that forms on the surface, these sheets are protected from external influences, and that layer can be additionally strengthened by an anodizing process.
Aluminum sheets appear on the market in different forms adapted to specific needs:
- Sheets on boards: Standard dimensions (e.g. 1000x2000 mm, 1250x2500 mm) with thicknesses from 0.3 mm to over 10 mm.
- Roll sheets: Practical for continuous production, often in thicknesses from 0.5 mm to 1.0 mm.
- Ribbed (tread) sheets: Also known as "quintet" or "diamond" sheets, used for floors and stairs due to their anti-slip properties.
- Perforated sheets: Used for decoration, ventilation and facades.
- Profiled (trapezoidal) sheets: Ideal for roof and facade coverings.
Key benefits:
- Lightness: They are three times lighter than steel, which drastically reduces transport costs and facilitates assembly.
- Non-toxicity: Safe for direct contact with food, which is why they dominate kitchenware and packaging.
- Conductivity: Excellent conductors of heat and electricity, making them indispensable in electronics and the auto industry.
- Recyclability: Aluminum can be endlessly recycled with minimal energy consumption compared to primary production.
