The central vacuum electric brush of Mr. Zeng's new project showed rust after a period of use, which not only affected the aesthetics, but also affected the company's reputation.

Mr. Zeng was puzzled because the base of the central vacuum electric brush has been replaced with galvanized steel, why rust still appears. In order to solve the problem as soon as possible, Mr. Zeng contacted Mr. Wang, the business manager of Aoqun. After learning about the current situation of Mr. Zeng, Mr. Wang informed Mr. Zeng that there are several reasons for the rust of the galvanized sheet of the central vacuum electric brush:

1) The galvanized sheet is impure and penetrates impurities such as iron.

2) The zinc coating on the surface is uneven, exposing the metal inside, causing corrosion.

3) Improper storage, scratching, bumping, water intrusion and steaming may also cause rust.

The materials used by Aoqun central vacuum electric brush are carefully selected, and we will never use inferior products for cheap. The materials purchased by Aoqun are accompanied by the supplier's material report. For Mr. Zeng’s problems, if you want to solve the rust problem, it is recommended to use 304 stainless steel or better, 316 stainless steel, so you don’t have to worry about rust. Hearing what Mr. Wang said, Mr. Zeng readily placed the first batch of orders.

A month later, Mr. Zeng contacted Mr. Aoqun Wang again and said that thanks to Mr. Wang’s suggestion, the central vacuum electric brush never showed rust after use. Mr. Zeng decided to sign an annual contract with Aoqun for long-term cooperation.
