This article provides a comprehensive analysis of the core knowledge of galvanized steel sheets. It first explains the rust-proof principle of galvanized steel sheets, especially hot-dip galvanized steel sheets—providing a physical barrier and cathodic protection through the zinc layer. It then focuses on comparing the differences between spangle-free and spangle-plated galvanized steel sheets in terms of surface characteristics, processing technology, application scenarios, and price. Finally, for the selection of galvanized steel sheets for construction, it offers practical selection suggestions based on aesthetics, cost, and weather resistance, emphasizing the importance of rational configuration according to different specification requirements.
