Mr. He, a door manufacturer from Guangdong, contacted Aoqun and asked if Aoqun has a flame-retardant door brush bar.

After getting in touch with Mr. He, Mr. Aoqun Liu kindly invited Mr. He to visit the company. It just happened that the workshop was producing UL94-V0 door brush bar products for export to Australia, and Mr. Liu performed V0 flame-retardant door brush bar products on the workshop site. Explanation. Mr. Liu said: “This door brush bar has a number of invention patents. The UL94-V0 flame-retardant door brush bar of this escalator brush is of good quality and has undergone a number of inspection procedures to strictly ensure that the brush has good tensile strength, do not shed hair." After hearing this, Mr. He said he would take samples to the customer for confirmation.

One week later, Mr. He reported that the customer was very satisfied with the sample. This door brush bar has good tensile strength and resilience. It is the product they need to find. He will immediately place an order for 50,000 meters and will send the subway screen door for his foreign project. The door brush bars are replaced with Aoqun brushes.
