Product quality inspection methods
The production process of galvanized coils undergoes strict quality control to ensure product reliability and performance. First, the chemical composition and mechanical properties of the raw materials are tested to confirm compliance with production standards. Next, specialized equipment is used to check coating thickness and uniformity, ensuring that the coating quality of each roll meets the required specifications. Surface quality is also rigorously inspected to eliminate defects such as cracks, bubbles, or scratches. Additionally, mechanical property tests, including tensile and bending tests, as well as corrosion resistance tests like salt spray testing, are conducted to verify durability and resistance to environmental factors. Finally, the finished product is carefully packaged and undergoes a final inspection before shipment to ensure it meets transportation requirements.
