The rust of the lifting chain has always been a problem that plagues the majority of customers. So how to prevent the level 80 from rusting?
There are two main methods here, one: black, also called cooking black, oxidation of the chain surface, and generate a layer of black oxide film. As long as the oxide film does not fall off, it can play a role in rust.
The second is galvanized. It is also a chemical method. There are two types of galvanized and plating zinc. Although the rust -proof effect is good, it will affect the strength of the 80 -level lifting chain.
From level 80 to level 70, the sacrifice intensity is exchanged for surface rust.
In addition, when using and storing the level 80 chain, pay attention to rainproof and moisture -proof, and can effectively delay the rust of the chain in a dry environment.
Even if it is rust, there is no need to worry that it will not affect the strength and tension, it will only affect the aesthetics.
