Why do some medium duty casters get rusty soon after buying them?

They are all industrial heavy-duty casters. Some heavy-duty casters will not rust no matter how long they are used, while some heavy-duty casters will rust within a few days of use after purchase and cannot be used. What's going on? In fact, the reason why most heavy-duty casters rust is mostly related to the environment in which they are used. Now Angu heavy-duty casters will introduce relevant knowledge to you.

A large amount of research data shows that water and oxygen are the main causes of rust in industrial heavy-duty casters. In a humid environment, water volatilization in the air will chemically react with the surface of industrial casters to form an oxide film, commonly known as caster rust. Heavy caster rust appears brownish red, has low density, large volume, and is easy to fall off. If not handled in time, the entire industrial heavy-duty caster may rust and become brittle.

So, now that we know the reasons why industrial heavy-duty casters rust, what should we do to avoid this kind of situation? Angu believes that heavy-duty casters are better used and stored in dry places. If the use environment cannot be changed due to environmental problems, you can apply a layer of paint on the exterior of the industrial heavy-duty casters. Paint can isolate air and water, effectively preventing heavy casters from being oxidized.

In addition, those industrial heavy-duty casters that have become rusty must also be maintained in time. Wipe it clean with a paper towel and store it in a dry place for a period of time, then paint it and put it back into use.
