Fumach, a professional do aluminum profiles manufacturer. This afternoon, we are received a phone from customer Miss CAI. She said there is an aluminium tube to be customized production, currently it is to be exported to Europe and America. The product use in the outdoor. Miss CAI said: but don’t know what surface treatment to do.So don’t know how to choose between oxidation and spraying. Our colleague Mr.chen is very proficient in this aspect. He made a detailed explanation to Miss CAI according to the characteristics of these two surface treatments, suggesting that the customer do spraying better, because spraying in the outdoors can better protect the product and increase the ability of acid and alkali resistance. And there is a cost advantage over anodizing. Miss CAI heard the our manufacturer manager Chen's professional answer, very confident to make a decision. Because in the aluminum profile “Fumach” manufacturers can not only provide the service of the product itself but also have the partner value.
