Resista® – HOPPE's surface guarantee

HOPPE's surface guarantee

For our Resista® hardware, we offer a 10-year surface guarantee (see also “Guarantee”).


This hardware has undergone continual quality testing and, when new, conforms to the requirements of the European standard EN 1670 (“Locks and hardware – corrosion resistance – requirements and test methods”).



Resista® hardware is ideal for coastal areas and highly frequented areas such as public buildings, shops and hotels.



Dirt can easily be removed with a damp cloth. The use of caustic cleansers or chemicals should be avoided. No further special care is needed.
