Perfectly formed
door handle blanks are machined for hours on end in vibrating grinding drums. This is where the accuracy typical for FSB arises: radii and edges are machined delicately using tiny ceramic balls.
Humans and machines hand in hand
Robots grind the geometrical FSB door handle models. More complex forms and freeform surfaces call for the sensitivity of humans: FSB continues to rely on hand-crafting for these processes.
Hydroforming some stainless steel
FSB door handle models are bent from pipe sections.
They are hydraulically shaped through multiple stages –
a technology perfected by FSB for door handle production.
Classics for modernity
The timeless beauty of bronze inspired FSB to produce fittings that accentuate the design through their unique materiality. The copper and tin alloy used by FSB also impresses with outstanding corrosion resistance, high tensile strength and great hardness.
Beauty in use
Bronze fittings grow in charisma over the years as they develop the patina typical of the material.
This patina has a particularly aesthetic appeal and is
testimony to the individual use.
Patina ex works
Bronze fittings are tarnished and then treated using a procedure developed specifically by FSB.
A dip for copper-based metals imitates the material’s natural ageing process – creating the
patina characteristic to bronze.
Aluminium is second nature to FSB
Machining and shaping aluminium has an almost 100-year history at FSB, and is the heart of the company’s material culture. The resulting wealth of experience guarantees unsurpassed quality, from the molten mass to the finished product.
Gravity die casting
Aluminium door handles are cast by hand. At a temperature of 660 degrees Celsius, the light alloy is removed in the ladle and shaped via gravity die casting: The aluminium fills the mould cavity via gravity alone.
Tools for tools as an extension of the hand
A special tool is used for every aluminium door handle model. With roughly 50 different designs, the FSB range stands out with a unique variety – from classics by Johannes Potente to the equally edgy and ergonomic model FSB 1185 by Andreas Heupel.
