Products prone to rust can be processed with Parkerizing treatment to increase rust resistance. Rust resistance can be enhanced further by having an anti-rust oil layer after Parkerizing.
When metal is cut or grinded, the fresh surface is susceptible to rust. Therefore, metal products should be treated with anti-rust oil after processing.
In the case of anti-rust oil treatment, the metal surface should be well cleaned in advance.
At our factory, we use Parkerizing (phosphate treatment) as a rust prevention measure.
