Product quality inspection methods
The production process of galvanized steel coils is governed by stringent quality control measures to ensure consistent product reliability and performance. It begins with the testing of the chemical composition and mechanical properties of raw materials to confirm compliance with industry standards. Specialized equipment is then used to assess coating thickness and uniformity, ensuring that each coil meets the specified requirements. The surface quality is meticulously inspected to eliminate defects such as cracks, blisters, or scratches. Further evaluations include mechanical property tests—such as tensile strength and bending tests—as well as corrosion resistance testing, including salt spray tests, to verify long-term durability under adverse environmental conditions. Finally, the finished coils are securely packaged and undergo a comprehensive final inspection before shipment to ensure they meet all transportation and handling standards.
