Small spangle galvanized steel coil is a type of galvanized steel that has a smaller, tighter, and more uniform spangle pattern on its surface compared to regular spangle galvanized steel coil. The spangle refers to the visible crystal structure on the surface of the galvanized steel that forms during the hot-dip galvanizing process.
The small spangle pattern is achieved by controlling the zinc-coating process, which results in a finer and more uniform crystal structure. The result is a smoother and more uniform appearance on the surface of the galvanized steel. Small spangle galvanized steel coils also have a better surface finish and are less prone to flaking or peeling.
Small spangle galvanized steel coils are commonly used in applications where appearance is important, such as building facades, decorative panels, and automotive components. They are also used in applications where corrosion resistance and durability are required, such as roofing, siding, and fencing.
Overall, small spangle galvanized steel coil offers improved appearance, surface finish, and corrosion resistance compared to regular spangle galvanized steel coils.
