Aluminium Pure

Aluminium shines with many positive properties in terms of processing, use and, above all, recycling. The material can be recycled again and again without loss. It is very pleasant to the touch - above all because this lightweight metal adapts particularly well to the ambient temperature. FSB only uses aluminium for its hardware for doors and windows with a footprint of 4 kg CO₂/kg - a quarter of the global average.

The new Aluminium Pure surface with its unique multifaceted appearance is a symbol of sustainability, as the last three steps of conventional aluminium processing are eliminated.

No fine dust is created by polishing or blasting, nor is the fitting anodised. This saves water and electricity and facilitates recycling at the end of the life cycle. Compared to the natural anodised aluminium surface, a further 37 % of energy is saved.

Aluminium Pure proves how good sustainability can look. The unique look results from the unconcealed naturalness of a largely untreated surface. The matt and almost "raw" appearance has a different effect depending on the ambience and interior concept. For example, Aluminium Pure blends in particularly harmoniously with exposed concrete walls and natural wood.

Over the years, handles made of aluminium Pure gain in radiance and charm: as the surface is not protected by an anodised layer, it changes over time in the areas that have been touched. Architects already know and appreciate this "patina of use" on FSB bronze products.

FSB offers three product collections in the Pure aluminium finish - including the FSB 1289, FSB 1292 and FSB 1267 designs, the latter of which pays homage to the lever handle designs by architect and Bauhaus director Ludwig Mies van der Rohe.

Our quality aspirations are exemplified by a process that has been perfected over decades, in which products are cast in aluminium at a temperature of 660 degrees Celsius. The molten alloy is poured directly from a ladle into the die. The aluminium fills the cavity and is shaped exclusively under the force of gravity.

After cooling, the casting is inspected for quality and the sprue is removed for recycling. The blank is then sanded by hand and forwarded for its final surface treatments. Vibratory finishing of the blanks in drums typifies the exactitude for which FSB is known.

The edges and corners are gently deburred and brightened by rubbing against small ceramic cones. Depending on the client’s wishes, the surface is finally polished or blasted and, for colour finishes, either anodised or powder-coated.

Bauhaus-Museum, Weimar

The Aluminium Pure surface is already in use at the Bauhaus Museum in Weimar. It blends harmoniously into the workshop and industrial character of the building. Together with FSB, architect Heike Hanada developed a special version of the FSB 1147 lever handle to match the proportions of the museum doors.
