1. Although hot-dip galvanized steel is currently the most widely used material in construction, there is still a lack of high-quality substrates such as zinc-free flat galvanized coils or zinc alloy coated coils. This limits the overall performance and application range of the material.

2. The variety and quality of domestic coatings are not sufficient to meet market demands. High import costs of premium coatings reduce competitiveness, and materials like plastic films required for color coating still rely heavily on foreign imports. There is a clear gap in advanced, thick-coated, functional, and high-strength colored coatings with rich color options.

3. Product standardization is lacking, leading to significant resource waste. Many small-scale units with annual capacities below 40,000 tons face issues with product quality and environmental protection, further complicating industry sustainability.

4. The number of new color coating units has surged, far exceeding actual market demand. As a result, many facilities operate at very low capacity, and some have even ceased production entirely, indicating overcapacity and inefficiency in the sector.

These challenges highlight the need for better standardization, investment in high-quality materials, and more strategic planning to ensure sustainable development in the steel and coating industries. By addressing these issues, the sector can improve efficiency, reduce waste, and enhance its global competitiveness.
