Galvanized Steel Coil
Product Introduction of Galvalume Steel Coil
The coating types of hot-dip galvanized products include pure zinc coating and alloyed coating, and can be supplied in the form of equal thickness plating and differential thickness plating.
In line with the service concept of “people-oriented, environmental protection”, Baowu can produce hot-dip galvanized products with no lead in the zinc layer, and the surface structure shows zero spangle.
The hot-dip galvanized substrate raw materials are provided by the cold and hot rolling production line, thus ensuring the stability of the chemical composition of the raw materials, the purity of the steel and excellent dimensional accuracy.

Galvanized Steel Coil Classification and code of surface structure
| 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. |

Types of galvanized steel coils
According to the production and processing methods can be divided into the following categories.
Type | Performance |
Hot-dip galvanized steel sheet | The thin steel plate is dipped into the molten zinc bath, so that the surface of the thin steel plate adheres to a layer of zinc. At present, the main use of continuous galvanizing process, that is, the rolls of steel continuously dipped in the molten zinc bath made of galvanized steel. |
Alloyed galvanized steel sheet | This type of steel is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to about 500°C to produce an alloyed film of zinc and iron. This type of galvanized steel has good paint adhesion and weldability. |
Electro-galvanized steel sheet | This galvanized steel sheet is manufactured by electroplating method with good processability. However, the coating is thin and the corrosion resistance is not as good as that of hot dip galvanized steel. |
Single-sided & double-sided poorly galvanized steel sheets | Single-sided galvanized steel sheet, i.e., a product that is galvanized on one side only. It has better adaptability than double-sided galvanized steel in terms of welding, painting, rustproof treatment and processing. To overcome the shortcomings of uncoated zinc on one side, there is another type of galvanized steel with a thin layer of zinc on the other side, i.e. double-sided galvanized steel. |
Alloy, composite galvanized steel sheet | It is made of zinc and the other metals such as aluminum, lead, zinc, etc. alloy or even composite plating into the steel plate. This kind of steel sheet has both excellent rustproof performance and good coating performance. |
