Australian customer purchase powder coating pre galvanized steel square tube. After customers receives the goods for the first time . Customer tests adhesive strength between the powder and the surface of the square tube .Customers test powder and square surface adhesion is small . We have meetings with customers to discuss this problem and we do tests all the time . we polished the surface of the square tube . Send the polished square tube to the heating furnace for heating . We tests all the time and discuss with customer all the time . We keep finding ways . After many tests, the final customer is very satisfied with the products. Now customer purchase a large number of products from factory every month.
The customer purchased steel pipes in our factory. After the goods were produced, the customer came to our factory for inspection.

Since we are an direct manufacturer and not a trading company, we pass the price advantage directly onto our customers. Additionally, we directly control production schedules to ensure quality and timely delivery.
We have secured 3 patents (including Groove pipe, Shoulder pipe, and Victaulic pipe). Our manufacturing setup includes 4 pre-galvanized product lines, 8 ERW steel pipe product lines, and 3 hot-dipped galvanized process lines.
Our factory is located just 40 kilometers from Xingang Port, which is the largest port in the north of China. This proximity enables fast, efficient logistics and shipping.
We actively collaborate with customers to run ongoing tests and adjust our processes. For example, for an Australian client experiencing low powder-coating adhesion on square tubes, we repeatedly tested and refined our process by polishing the tubes and utilizing specialized furnace heating until the product met their standards, leading to a long-term monthly ordering relationship.
