Suppliers Hot Dip Gi Galvanized Steel Coil /Metal Roofing Coil Price
The galvanized coil is a thin steel plate in which a thin steel plate is immersed in a molten zinc bath to adhere a layer of zinc to the surface.Galvanized steel is a surface treatment technique that coats a layer of zinc on the surface of a metal, alloy or other material for aesthetics, rust prevention, and the like. The main method used is hot-dip galvanizing. Zinc is easily soluble in acid and soluble in alkali, so it is called an amphoteric metal. Zinc hardly changes in dry air. In moist air, a dense zinc carbonate film is formed on the zinc surface. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine, the corrosion resistance of zinc is poor, especially in the atmosphere containing high temperature and high humidity containing organic acid, the zinc coating is easily corroded.
The standard electrode potential of zinc is -0.76V. For steel substrates, zinc coating is an anodic coating. It is mainly used to prevent corrosion of steel. Its protective performance has a great relationship with the thickness of the coating. After passivation, dyeing or coating of the photoresist, the zinc coating can significantly improve its protection and decorative properties.

Main Features
1.Anticorrosive:13 years in heavy industrial areas,50 years in the ocean,104 years in the suburbs and 30 years in cities.
2.Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
3.Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
4.Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
5.Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
6.Save time and energy:Galvanizing process is faster than other coating methods.
