【SMM Science: What's the Difference Between Galvanized Steel with and without Spangles?】Galvanized steel coils refer to steel sheets that have undergone hot-dip galvanizing or electro-galvanizing processes, usually existing in the form of coils. The galvanizing process involves bonding hot-rolled steel with zinc to enhance its corrosion resistance and extend its service life. This material is widely used in various industries such as construction, home appliances, automobiles, machinery, and more, due to its excellent corrosion resistance, strength, and workability, making it particularly suitable for outdoor or wet environments.
