Miss Su, who is engaged in the door industry, said that she has always received complaints from customers, saying that the draught excluder brush strip are rust, affecting the appearance, need suppliers to re-supply. The replacement of goods has caused adverse effects on the company's reputation. She hopes to re-select the quality supplier cooperation.

We learned that draught excluder brush strip purchased by Miss Su's customer was installed on the freezer door. Since the base of the draught excluder brush strip is made of electrolytic plate, the properties of the electrolytic plate are only treated with a layer of anti-rust material on the surface. If the surface is scratched or in a humid environment, it is more likely to rust and affect the appearance. Under the premise that the customer does not require the material of the brush base, we recommend Miss Su to use 304 stainless steel or 316 stainless steel. Both materials have the advantages of corrosion resistance, oxidation resistance and rust resistance. Miss Su listened to our analysis. After that, she felt very reasonable. She had to feedback with the customer before I decided to change the material.

Two days later, I received a call from Miss Su, saying that her client felt that this proposal was very professional and was willing to increase the price to change the material. On the same day, she gave us a sample of draught excluder brush strip.
