Application:
DX51D galvanized steel sheet consists of five parts: product use code, steel type code, steel properties, hot-dip code (D) and coating type code, among which hot-dip code (D) and coating code are connected by "+".
DX of DX51D: the first letter D indicates flat steel for cold forming; the second letter X indicates that the rolling state of the substrate is not specified.
The steel grade characteristic of DX51D galvanized steel sheet is low carbon steel.
1. DX51D+Z: It is one of the most commonly used coating types in manufacturing and construction.
2. DX51D+ZF: Suitable for exterior parts such as automobiles and home appliances.
3. DX51D+ZA: Primarily used in applications where good ductility is required (eg deep drawn parts) and where moderate corrosion resistance is required.
4. DX51D+AZ: Suitable for environments requiring high corrosion resistance, high temperature resistance and heat reflectivity, such as roofs and walls.
DX51D Galvanized Steel Sheet is widely used in construction,steel cable trunking,ventilation duct, agricultural greenhouses, billboard, roller door, galvanized bucket.etc.
