Spangled galvanized steel sheet is the spangle obtained by the condensation of the zinc coating under normal conditions after galvanizing. It is mainly used in buildings and other places where there is little direct contact with the human body.
Galvanized steel sheets without spangles are mainly produced through a special production process to control the lead in the zinc pot to a certain level, or after the strip steel is out of the galvanized pot, it undergoes special treatment to control the spangles to less than a certain level. Mainly used in home appliance housing

Surface treatment of galvanized steel coil
| Surface treatment type | Code | Feature |
|---|---|---|
| Chromic acid treatment | C | Good corrosion resistance, suitable for bare state |
| Chromic acid treatment + oiling | S | Good corrosion resistance |
| Phosphoric acid treatment (including sealing treatment) | P | A certain degree of corrosion resistance, good paint performance |
| Phosphoric acid treatment (including sealing treatment) + oiling | Q | It has certain corrosion resistance, good paint performance, and prevents rust during transportation and storage |
| Phosphoric acid treatment (excluding sealing treatment) | T | A certain degree of corrosion resistance, good paint performance |
| Phosphoric acid treatment (excluding sealing treatment) + oiling | V | Have certain corrosion resistance, good paint performance, and prevent rust |
| Oiled | O | Prevent rust during transportation and storage |
| No treatment | M | Suitable for immediate painting |
Chromate treatment of galvanized steel coils is also called passivation treatment. Through passivation treatment, the surface structure and gloss of the galvanized layer can be improved, the corrosion resistance and service life of the galvanized layer can be improved, and the bonding force of the coating and the base metal can be improved.
The purpose of oiling galvanized steel coils is a protective layer is formed on the surface of the steel coil to prevent the surface from rusting.

Types of zinc coating of galvanized steel coil
Hot-dip galvanized coils are divided into pure zinc coating and zinc-iron alloy coating according to the coating. Their common point is that the zinc content of the zinc solution in the zinc pot is the same. The difference is that the zinc-iron alloy adds an alloying process.
