The gi sheet color is not uniform, but varies depending on its manufacturing process and processing methods. The following is a detailed introduction to the gi sheet color:
1. Basic color
Galvanized steel plates are usually uniformly gray in color, with a metallic luster, and resistant to fingerprints. This type of steel plate has superior corrosion resistance while maintaining the processability of cold-rolled plates. Hot dip gi sheet generally appear bright white. The surface of hot-dip galvanized steel plate may have zinc flowers, with small zinc flowers being difficult to see, while large zinc flowers can clearly show hexagonal flower blocks. The rust resistance of hot-dip gi sheet is better than that of electroplated gi sheet under the same conditions.
2. Color after passivation
After passivation treatment, gi sheet color can exhibit different. Passivation is a chemical treatment process aimed at further improving the corrosion resistance of galvanized layers. Common passivation colors include:
1. Silver white: This is the basic color of galvanized steel plate after passivation, similar to the color of hot-dip galvanized steel plate without passivation.
2. Light yellow: Galvanized steel plates may appear light yellow under specific passivation agent treatment.
3. Other colors: Using different passivators, gi sheet can also be passivated into various colors such as sky blue, black, colored, military green, etc. The selection of these colors mainly depends on the type of passivating agent and process conditions.
3. Colors under special craftsmanship
In addition to the basic color and passivated color, gi sheets can also obtain other colors or textures through special processes. For example:
1. Colored gi sheet: Through specific painting or printing processes, rich colors and patterns can be formed on the surface of gi sheet.
2. Printing and coating galvanized steel plate: Printing and coating treatment can be carried out on the surface of galvanized steel plate to obtain steel plate with specific texture and pattern.
3. Polyvinyl chloride laminated galvanized steel plate: By stacking plastic materials such as polyvinyl chloride on the surface of the galvanized steel plate, a composite material with specific colors and textures can be formed.
In summary, gi sheet color come in a variety, from basic gray and white to passivated silver white, light yellow, and other colors, as well as textures and patterns such as color and printing under special processes, meeting the needs of different fields and occasions. When selecting gi sheet, the appropriate color and process should be chosen based on specific application scenarios and requirements.
