A bar of aluminium was a great sensation at the 1855 World Exhibition in Paris.
This “silver made from clay” was admired as a priceless rarity. Today we know that, next to oxygen and silicon, aluminium is the third most common element in the Earth’s crust. Aluminium is a light, silvery-white metal that can be cast and rolled into virtually any conceivable form including extremely thin sheets. But attractive appearance and easy handling are not the only reasons for the popularity of aluminium as a door furniture material. It is also pleasing to the touch, since it adopts the temperature of its surroundings particularly well and quickly.
True, the amount of energy required to extract raw aluminium is relatively high. However, this negative energy balance is more than offset by the metal’s many advantages in processing, use and, above all, recycling. The energy savings achieved in recycling compared to the extraction process amount to almost 95%, and aluminium can be recycled over and over again without any of it being lost.
After machining, the surface is anodised for protection. The silvery layer of oxide can be stained to extend the range of possible finishes. FSB applies two different methods: either the surface is stained by immersion, with the dye solution penetrating to the middle of the oxide layer, or the oxide layer is deep-stained by an electrolytic process. Once colouration is complete, the surface is sealed to achieve high corrosion resistance as well as fastness to light and weathering. Basically, aluminium needs no special care. Its surface is protected by natural or artificial anodising. Marks can be removed with water and a soft cloth.
The natural colour of aluminium is silver. We recommend this colour to all customers with a preference for designs that match the materials used. FSB offers several surface variants as listed below:
FSB 01 Aluminium natural colour
FSB 02 Aluminium German silver-colour
FSB 03 Aluminium brass-coloured
FSB 04 Aluminium bronze-coloured
FSB 07 Aluminium dark bronze colour
