Galvanized steel coil surface structure classification and code
| surface structure | Code name | Characteristic | Use |
| Normal Spangle | Z | After galvanizing, the zinc layer is condensed under normal conditions and the spangles are obtained. | General uses |
| Small spangles | X | A surface formed by controlled condensation of the zinc layer, exhibiting fine spangles that are smaller than normal spangles | For applications where normal spangles cannot meet surface appearance requirements. |
| Regular Spangles | G | Surface structure obtained by special finishing treatment. | For applications requiring high surface quality, e.g. as color-coated substrates. |
| Smooth small spangles | GX | ||
| Zero Spangles | N | A specific production process is used to make the surface of the coating free of visible spangles. | － |
| Zinc-iron alloy | R | Zincless, gray, generally dull. | Suitable for further painting. |
