The scope of the 80 -level lifting chain is relatively wide. The requirements for surface treatment are not the same. The role of surface treatment can not only make the appearance of the chain look beautiful. Some surface treatment can also delay the oxidation and rust of the chain surface, thereby increasing the service life of the chain. Electric swinging is a layer of coating on the surface, which is one of the lifting of chain surface treatment. This type of surface -processed chain will not be applied to the lifting gourd and cross wheels. Because the chain after the electrophoresis is beautiful, the surface luster is better, but scratches are prone to appear after friction. Therefore, because the use of the chain is different, the surface treatment is different. The more common surface treatment is: primary color (polishing), black (black), galvanized, dipping, electric swimming.
