Superior galvanized sheet Market size

Sometimes some customers call us and ask if they can order galvanized sheet in a specific color. We also ask the manufacturers why, although the amount of heat and force they give to galvanized sheet is the same, the color of the sheets obtained this week is different from the color of last week and their steel has a special color today. The truth is that the galvanizing job has little control over the final specific color. For more information on Superior galvanized sheet market size, visit our site.

The brief introduction to Superior galvanized sheet

The basis of the production of galvanized coating is the metallurgical reaction between the steel and the molten zinc element in the galvanizing bath. This reaction causes the formation of an outer shell (light silver) and several layers of iron (dark) alloy. Certain elements in steel (mainly silicon, phosphorus, carbon and manganese) can significantly affect the reaction between steel and metal on the molten metal.

If the reaction rate increases or the cooling time continues at a lower temperature, a small percentage of iron (about 0.5% iron) can be removed from the steel and reach the surface of the galvanized coating. This makes the finish of colored galvanized sheet darker and dull, sometimes even with a spider-like design. Sometimes it is natural for adjacent areas to have light and dark colors and this will be slightly different due to the difference in the relative concentration of the above mentioned items or the amount of cooling temperature.

Basically, steel with darker areas contains elements that are not suitable for the production of light silver-plated galvanized steel. On the sides or holes, you may see lighter coatings with a darker color in between and cool slowly. This is normal for steels with higher reactivity and does not harm the lifetime of the coating. In fact, darker areas often have thicker coatings than lighter areas because they are more reactive. Thicker coatings can be more fragile than standard coatings, so they require more care during installation. It is noteworthy that everything galvanized first turns to a light silver color.

This happens when the items turn dark or opaque gray and part of the leaf is suspended in the air to cool. We hope all colored galvanized sheets will be bright and shiny, but any galvanized worker should see that in some cases, the galvanized product darkens in front of their eyes and can only hang.
