Galvanized steel strips can be finished in various ways, with some common options including:
1. Regular Spangle: This finish displays a shiny, crystalline pattern on the surface. It occurs naturally during the galvanization process when the zinc coating solidifies.
2. Mini Spangle: Smaller and closely spaced spangles characterize this finish, giving it a smoother and more uniform appearance compared to the regular spangle.
3. Zero Spangle: This finish lacks visible spangles, resulting in a matte or dull appearance. It is achieved by applying a special chemical treatment during galvanization.
4. Skin Pass: By passing the galvanized steel strip through rollers that compress and flatten the surface, this finish improves the strip's flatness and smoothness.
5. Bright Finish: A thin, transparent organic coating is applied over the galvanized surface to achieve this finish. It not only enhances the aesthetics but also provides additional protection against corrosion.
It is worth noting that the choice of surface finish for galvanized steel strips depends on the specific application and requirements.
Some common surface finishes for galvanized steel strips include:
1. Regular Spangle: This finish is characterized by a shiny, crystalline pattern on the surface. It is achieved by allowing the zinc coating to solidify naturally during the galvanization process.
2. Mini Spangle: As the name suggests, this finish has smaller and more closely spaced spangles compared to the regular spangle. It provides a smoother and more uniform appearance.
3. Zero Spangle: This finish has no visible spangles on the surface, giving it a matte or dull appearance. It is achieved by applying a special chemical treatment during the galvanization process.
4. Skin Pass: This finish is obtained by passing the galvanized steel strip through a set of rollers that compress and flatten the surface. It helps to improve the flatness and smoothness of the strip.
5. Bright Finish: This finish is achieved by applying a thin, transparent organic coating over the galvanized surface. It enhances the aesthetics and provides additional protection against corrosion.
It is important to note that the choice of surface finish may depend on the specific application and requirements of the galvanized steel strip.
Some common surface finishes for galvanized steel strips include regular spangle, minimized spangle, and zero spangle.
