This article systematically analyzes the influence of different coating weights on the protective performance and industrial adaptability of metal surfaces, addressing a critical challenge in modern metallurgical engineering and materials science. As industrial demands for durable and versatile materials continue to rise, understanding the precise relationship between coating parameters and material longevity becomes essential. In this study, we conduct a comprehensive investigation by comparing the effects of coating thickness changes on key performance indicators, including corrosion resistance, surface uniformity, and processing adaptability. The experimental framework involves rigorous corrosion tests, such as salt spray and electrochemical impedance spectroscopy, alongside detailed microstructure characterization using scanning electron microscopy and X-ray diffraction. These methodologies are applied across three distinct and widely utilized coating systems: traditional hot-dip galvanizing, advanced aluminum zinc plating, and highly resilient galvanized aluminum magnesium systems. By systematically evaluating these variations, the research identifies optimal coating weight thresholds that maximize structural integrity without compromising formability or increasing manufacturing costs. The results indicate that reasonable control of coating weight can effectively balance the protection life and application requirements under diverse environmental conditions. Furthermore, the findings reveal that the galvanized aluminum magnesium system exhibits superior performance at lower coating weights compared to conventional alternatives. Ultimately, this comprehensive analysis provides a robust, empirical basis for the selection and optimization of industrial coating products, offering valuable insights for engineers and manufacturers aiming to enhance the sustainability and reliability of metal infrastructure.References
