More info


The door handle Viola by Colombo Design is available in many colors. 10 years warranty on all handles Colombo. The warranty can be extended up to 30 years with the Zirconium HPS finish. 


Colombo Design also developed a treatment of protection 30 years guaranteed on the finish Zirconium Gold and Zirconium Stainless-Steelwhere are previously coated with layers of copper, nickel and chrome in order to guarantee the perfect insulation of the underlying raw material. The use of these products is strongly recommended in such places as high-salinity marine areas subject to acid rains. The use in bright sunshine and temperature ranges does not cause color changes. The hardness of the coating and the low rate of surface friction ensure a very good resistence to scatches due to the use of rings (for example). Any dents due by hits or impact can spoil the surface and effect the coating performance.
