Manager Ou is the manager of a decoration company. He has recently received a project for a new real estate and is responsible for the decoration of sample rooms and later real estate. Because it is a high-end residential area that uses wooden floors, the weather stripping for garage door used before has scratched wooden floors after being installed and used for a period of time. Now that he has received a written rectification letter from the real estate owner, Manager Ou is very headache. After searching for experts who knew about Aoqun, he brought samples directly to Aoqun.

Mr. Chen from Aoqun received Manager Ou. After understanding the situation and carefully inspecting the original weather stripping for garage door, he found that the original brush wire was made of PP and the wire diameter reached 0.3mm. The PP itself was harder. If the wire diameter is too large, it will be thicker. Rubbing on the floor often, it will scratch the floor after a long time. Mr. Chen suggested that Manager Ou directly change the material, adopt more flexible and resilient PA material, and reduce the wire diameter to 0.2mm, which can fundamentally solve the problem of weather stripping for garage doors. Later, at the request of the manager of Europe, samples were sent for testing on the next day.

15 days after the weather stripping for garage door was replaced in the sample room, Manager Ou was affirmed by the developer because of the proper improvement of the weather stripping for garage door in the sample room, and directly signed the subsequent renovation contract. Manager Ou also decided to replace all weather stripping for garage doors with Aoqun, and placed an order for 100,000 meters.
