Vitra most frequently uses aluminium and steel for metal components. Since 94% less energy is required to produce recycled aluminium in comparison to primary aluminium, Vitra utilises aluminium consisting of 95% recycled material whenever possible. Depending on the product, metal surfaces are either powder-coated, chrome-plated, polished, galvanised or lacquered. A smooth or textured powder-coated finish provides colour and surface protection.
