An Australian customer purchased powder coating pre-galvanized steel square tubes. After receiving the goods for the first time, the customer tested the adhesive strength between the powder and the surface of the square tubes, finding that the adhesion was insufficient.
We organized meetings and ran continuous tests to resolve the issue. By polishing the surface of the square tubes and heating them in a specialized furnace before coating, we successfully optimized the process. After extensive testing, the customer was completely satisfied with the product performance. Currently, the customer purchases a large volume of products from our factory every month.
