Mr. Xie is a brand customer of industrial doors and needs a large number of brush strip sealing systems every year. Because Mr. Xie's products are used in Southeast Asia, where the area is relatively humid and seawater is poured, the brush is rusted. Mr. Xie also received some complaints from customers. The customer has not returned the order. Mr. Xie is very upset about this. 

Listening to the introduction of his friend, he learned that AOQUN is a professional manufacturer of industrial dust-proof brush strip sealing systems. Mr. Xie decided to visit AOQUN and seek solutions to the problem of brush rust. AOQUN Mr. Zhao received Mr. Xie. Through communication, it is analyzed that there are two reasons for the rust of the brush strip sealing systems:

1, The 304 stainless steel is not pure material, there are additives, so there will be rust phenomenon;

2, Due to the special characteristics of the use of the area, there is seawater infusion, then you should use better stainless steel, Mr. Zhao recommended that Mr. Xie directly replace 316 stainless steel.

AOQUN has 316 stainless steel brush samples, can let Mr. Xie take the on-site test. Finally, Mr. Xie took the 316 stainless steel brush sample to test whether it rusted.

After 15 days, Mr. Xie called and said: "I have tried the brush samples, no rust. My previous brush strip sealing systems were rusted after more than 10 days of seawater erosion. It seems that 316 stainless steel is sure to meet my brush strip sealing system requirements. Thank you for providing me with professional advice, let me take less detours. I will place the next batch of orders.”
