An Australian customer purchased powder coating pre-galvanized steel square tube. After receiving the goods for the first time, the customer tested the adhesive strength between the powder and the surface of the square tube, finding it to be insufficient. We held meetings with the customer to address this issue and conducted continuous tests. By polishing the surface of the square tube and passing it through a heating furnace, we refined the parameters. Through continuous collaboration, testing, and troubleshooting, we achieved a final product that left the customer highly satisfied. Today, this customer purchases a large volume of products from our factory every month.
