GRIFFWERK is not limited to noble design - we are proud of the inner values of our products. We exclusively use stainless steel of alloy 304, also known as "1.4301". This high quality steel is - matt or polished - due to its composition stainless with special corrosion resistance and durability. Stainless steel forms a very thin protective passive layer, which rebuilds even after surface damage caused by chemical reactions.

GRIFFWERK recommends the "GRIFFWERK Care Spray", which is specially designed for our products, to care for and maintain the value of your stainless steel door handles and fittings. It cleans intensively, has a dirt-repellent effect and thus maintains the value of your stainless steel room door set, door handles and door fittings. Please do not use any aggressive cleaning agents or scouring agents containing alcohol for cleaning - regardless of whether the stainless steel surface is matt, polished or shiny. Please note that the surface of the lever handle set can be damaged under extraordinary stress, for example by building dirt, grinding dust, aggressive vapors or salt water. For this reason, clean the handle set with GRIFFWERK Care Spray immediately after soiling. Our GRIFFWERK care spray is available from all our trade partners.
