world leader in the production of sinks in granite Franke. In particular sinks Fragranite DuraKleen (in pictures) eliminate cleaning problems associated with sinks made of composite materials. In this case, the granite particles agglomerated in the production phase are even more sensitive and form a more smooth and even surface, reducing the risk of scale deposits. Is also greatly reduced the deposit of debris, bacteria and food particles between grains, which can greatly improve the level of hygiene. The surface of Fragranite Durakleen presents smoother by about 30 # 37 and less irregular due to pi high proportion of small particles used. The use of new resins resizes surface tensions, promoting sanitation operations.
