Customer Picture
Customer Case
An Australian customer purchased powder coating pre-galvanized steel square tubes. Upon receiving the first shipment, the customer tested the adhesive strength between the powder and the surface of the square tube, finding the adhesion was insufficient. We immediately met with the customer to address this challenge, initiating continuous testing. Our team polished the surface of the square tubes and processed them in a heating furnace. Through constant communication and multiple rounds of refinement, we successfully resolved the issue. The customer was highly satisfied with the final optimized product and now places large-volume orders with our factory every month.
