FSB is amongst the pioneers for the environment. Our lights have been set to green since 1991. And we are the first architectural hardware company worldwide to be certified to ISO 14 025. But hopefully not the last!
Aluminium is in FSB’s nature
FSB has a tradition of working and shaping aluminium that stretches back almost a century and is at the very heart of the company’s approach to materials. The treasure store of experience amassed in the process ensures unsurpassed quality from the initial melt to the final product.
Gravity die casting
Door handles in Aluminium are cast by hand. The lightweight metal is scooped out at a temperature of 660 degrees Centigrade and formed into the required shape by a process known as gravity die casting: the aluminium fills the shaped cavity with the aid of nothing but the force of gravity.
Classic for the modern age
The timeless beauty of bronze has inspired FSB to fashion fittings whose unique materiality injects added texture into a space’s design. The copper-tin alloy FSB makes use of boasts superb resistance to corrosion, great tensile strength and great hardness, moreover.
Tools for extension-of-the-hand tools
There is a dedicated tool for every single door handle model made in Aluminium. The 50 or so different designs in the FSB range are a source of unparalleled variety – from the classic by Johannes Potente to FSB 1185, a model by Andreas Heupel that is as angular as it is ergonomic.
Man and machine both get hands-on
Robots add the finishing touches to geometrical FSB door-handle models, yet it is human judgment that counts where complex shapes or freely formed detail are involved: FSB continues to have such work performed by hand.
Shaped to perfection
Door-handle blanks are treated for several hours in a vibratory tumbler. This is where they attain the consummate quality so typical of FSB: their radii and edges are painstakingly gone over with a small ceramic sphere.
Beautiful through use
Fittings in bronze acquire added radiance over the years as their characteristic patina evolves. This patina has a particular aesthetic appeal whilst also bearing witness to individual patterns of use.
Internal High-Pressure Deformation (IHPD)
A number of FSB door-handle models in Stainless Steel are made by bending sections of piping. They undergo several phases of hydraulic deformation – a technique perfected by FSB specifically with a view to manufacturing its door handles.
Patina ex works
Bronze fittings are deadened, i.e. given a matt look, and then subjected to a treatment specially devised by FSB. An immersion bath for cupriferous metals mimics the material’s natural ageing process – thus allowing bronze’s characteristic patina to develop.
