The eco-friendly lightweight

Aluminum is the most commonly occurring metal in the Earth’s crust. First isolated in 1825, Aluminum has been used in many ways over the years. Napoleon used aluminum plates during French state dinners for distinguished guests while “rank and file” guests were only served on gold or silver plates. Today the auto, aeronautical, and aerospace industries widely use aluminum because of strength, durability, light weight, and aesthetic properties.

Anodized Aluminum

Right from the start, aluminum has been used as a high-tech material, when light weight and high durability are required. Space travel as well as aircraft and car making are inconceivable without it and it was responsible for making some innovations possible in the first place.

Especially in the second half of the 20th century, aluminum started its triumphal advance into interior design and into design in general. Its technological mystique together with its silvery, glittering surface opened up new horizons in the use of metal in interior design. At FSB this started with the designs by Johannes Potentes in the 1950s.

Still today, the expertise which we gained at the time in the machining of aluminum is the basis of all of FSB’s families of handles made of this wonderful material.

Aluminum is a light metal (density 2.699 g/cm3). It melts at 660 degrees Celsius. Admittedly, its initial extraction requires a relatively large amount of energy. This energy balance is however compensated by its many positive characteristics in use and when recycled. The energy savings associated with recycling are about 95% compared to its initial extraction. And aluminum can be recycled again and again, without any loss.

It is very pleasant to handle, above all as this lightweight amongst the metals is very good at matching the ambient temperature. FSB only uses pure alloys from the smelters to DIN 1725 with the following material numbers:

AlMg3: material no. 3.3541.02
AlMg1: material no. 3.3315
AlMgSi0,5: material no. 3.3206

FSB has enhanced its processing of aluminum by adopting a mix of manual and industrial methods that allows each of its many door handle designs to be “worked” out of the material to optimum effect. The anodized colors supplied by FSB take as their point of reference the classic metallic “colors” with which the builders’ hardware sector have specified since the 1950s to emulate typical real hardware metals by means of color-anodized aluminum finishes. What used to be an attractively priced alternative for private builders’ clients unable to afford (or unwilling to buy) door fittings in bronze has, however, since established itself as a design option in its own right for architecture and select interior finishing schemes.

FSB is revitalising “its” aluminium material with the aid of anodised colors based on refined matt-velvet aluminium finishes whose inimitable sheen and pleasant haptic quality lend them an allure of a kind never before seen. A conscious attempt to relate to the actual metal is made – “colour” in the sense of “colourful” is out. This is regardless of whether the host surface is highlighted by means of a metallic colour/finish or whether it is to play a more downbeat role – notably in the case of anodised or powder-coated window and facade profiles – as part of a scheme of coordinated shades.

In technical and functional terms, blasting an aluminium surface causes it to be compacted much in the same way as occurs during forging, as a result of which blasted anodised aluminium finishes are somewhat more resistant to knocks and scratches than traditionally worked and anodised aluminium.

Aluminum + color

FSB sees itself primarily as a manufacturer of door and window fittings made of fine metals. FSB offers a limited range of painted fittings. When making your custom color inquiry, please specify the RAL number of the required color. Account must always be taken of the fact that slight variations in color can arise in manufacturing, due the materials and the process involved.

As its basic material for painted fittings, FSB uses the cast and ground aluminum models from its standard range. Before painting, the parts are subject to a special, anodic oxidation. FSB then uses electrostatic powder coating. This is a solvent-free painting process.

The paint is applied in layers of approx. 80 μm. The quality of the finish, the light fastness of the colors, the hardness of the surface, resistance to abrasion etc. approximately correspond to that of anodized aluminum layers.

Occasionally FSB is asked whether we can supply door handles made of round material in designs made of painted stainless steel or steel. In contrast to using aluminum as the base material, especially when using steel, there is a risk of corrosion if the surface is damaged. We ask for your understanding, that for such special versions, we cannot accept any liability and must exclude any guarantee for the product.

If properly fitted and used properly, the paint on FSB fittings will withstand daily use. Vigorous contact with hard and sharp-edged objects (e.g. rings, keys, boxes etc.) can scratch the surface. Scratches do not however impair function.

FSB ErgoSystem®

FSB offers you the option, for all parts within the ErgoSytem which are made of aluminium and as standard are painted dark grey, to paint them on request with almost all colours to RAL. ErgoSystem® fittings for large buildings can be colourmatched to individual designs or their colours can set an accent. Please specify the required RAL number with every inquiry.
