Aluminium

The frames in the VELFAC 200-series are made of aluminium. Besides robustness, tensile strength and breaking strength, aluminium also makes the products easier to maintain. Aluminium reduces the need for maintenance materials and makes the products virtually maintenance free throughout their life cycle.

Aluminium has a long life and does not erode. The reason is that the material forms a protective layer of aluminium oxide when it is exposed to ambient air.    Constituting 8 percent of the earth's crust, aluminium is a natural material. It is the third most common substance on earth (after CO2  and silicon, i.e. sand). Next after iron, aluminium is the most widely used metal in the world.

Infinite recycling
Aluminium is a precious resource and a highly sustainable material. It is suitable for recycling, as it can be reused indefinitely and has a very limited loss of material properties.

The vast majority of aluminium is collected and reprocessed instead of being newly mined. Thus, 70 percent of all aluminium mined is still in use today. In Europe, more than 80 percent of aluminium building materials are reused.

By remelting the aluminium, greenhouse gas emissions are reduced by 95 percent, as the energy consumption is limited to a maximum of 5 percent of the quantities used for new production. The production process generates a small amount of aluminium cuttings, which are remelted for recycling.

Recycled aluminium can be used in a wide range of products, for example food, transport, technology and building materials.
