Structural Steel SS550GD SGC570 Full Hard GI Metal Tile Corrugated Roof Panel Z120g Galvanized Sheet Regular Spangle
Structural Steel SS550GD SGC570 Full Hard GI Metal Tile Corrugated Roof Panel Z120g Galvanized Sheet Regular Spangle
Hot-dip galvanised steel coil (GI) is made by passing a fully hardened steel sheet, which has undergone a pickling and rolling process, through a zinc pot, thereby coating the surface with a zinc film. Due to the properties of zinc, it offers excellent corrosion resistance, paintability and workability. Typically, the process and specifications for hot-dip galvanised steel sheet and galvanised steel coil are essentially the same.
Raw Materials and Production Process
- Sources: The raw materials for galvanized sheet products are sourced from renowned domestic enterprises such as Baosteel, Anshan Steel, Shougang, and Bensteel.
- Production Method: Utilizes the advanced US Steel Union Method for production.
- Automation: Employs a comprehensive automation control system from Germany's Siemens.
- Quality Control: The products have achieved international first-class standards in zinc-free household appliances galvanized sheet quality control and management, fully meeting the molding and processing requirements of various products.
Applications of Galvanized Steel Sheets and Coils
Galvanized steel sheets and coils are versatile materials used across various industries, including construction, light industry, automotive, agriculture, livestock, fishery, and commerce.
Construction Industry
- Usage: Utilized for producing anti-corrosive roof panels and roof grilles.
- Applications: Suitable for both industrial and civil construction purposes.
Light Industry
- Usage: Used to manufacture appliance housings, civil chimneys, and kitchenwares.
Automotive Industry
- Usage: Ideal for producing anti-corrosive auto parts.
Agriculture, Livestock, and Fishery Industries
- Usage: Applied in making storage and transportation appliances for grain, as well as frozen processing appliances for meat and aquatic products.
Commercial Industry
- Usage: Used to produce appliances for storage and transportation of goods and materials, along with packaging appliances.
Galvanised steel coils are thin steel sheets that are dipped into molten zinc in order to attach a layer of zinc to the surface. This is an effective method of corrosion protection that extends the life of the metal material.
Main characteristics of galvanised steel
-
Corrosion protection: 13 years for heavy industrial areas, 50 years for marine, 104 years for suburban areas and 30 years for urban areas.
-
Inexpensive: Hot dip galvanising costs less than other coatings.
-
Reliable: The zinc coating is metallurgically bonded to the steel and forms part of the steel surface, making the coating more durable.
-
Toughness: the galvanised steel layer forms a special metallurgical structure that can withstand mechanical damage during transport and use.
-
Comprehensive protection: every part of the coating can be galvanised and is fully protected even in depressions, sharp corners and hidden areas.
-
Saving time and effort: the galvanising process is faster than other coating methods.
