Mr. Zeng has been working as a buyer in the door industry. Recently, he has received complaints from customers that the strip air brush of the new project has rust after being used for a period of time, which not only affects the appearance, but also affects the company's reputation.

Mr. Zeng was puzzled because the base of the strip air brush has been replaced with galvanized steel, why rust still appears. In order to solve the problem as soon as possible, Mr. Zeng had to change the supplier and contacted Mr. Wang, the business manager of Aoqun after a friend's introduction and a call. 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: 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 strip air brush materials used by Aoqun are carefully selected. We will never use inferior products for cheap, and carry out incoming inspections in accordance with the national standard "GB/T30402-2013". All materials purchased by Aoqun are attached with suppliers. Material report. For Mr. Zeng’s problems, if you want to further completely solve the rust problem, it is recommended to switch to 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 order for strip air brush.

A month later, Mr. Zeng contacted Mr. Aoqun Wang again, and said that thanks to Mr. Wang’s suggestion, there was no rust after using the strip air brush, which was unanimously appreciated by senior leaders. Mr. Zeng decided to sign a 10,000-meter strip air brush contract with Aoqun for a long time.
