Product Detail
Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle. It can be identified by the crystallization patterning on the surface (often called a "spangle").
Like other corrosion protection systems, galvanizing protects steel by acting as a barrier between steel and the atmosphere. However, zinc is a more electropositive (active) metal in comparison to steel. This is a unique characteristic for galvanizing, which means that when a galvanized coating is damaged and steel is exposed to the atmosphere, zinc can continue to protect steel through galvanic corrosion (often within an annulus of 5 mm, above which electron transfer rate decreases).
Main Application
Features
1. Corrosion resistance: Galvanizing is an economic and effective rust prevention method that is often used. About half of the world's zinc output is used in this process. Not only does zinc form a dense protective layer on the steel surface, but it also has a cathodic protection effect. When the zinc coating is damaged, it can still prevent the corrosion of the iron base material by cathodic protection.
2. Good cold bending and welding performance: mainly used low carbon steel grade, the requirements have good cold bending and welding performance, as well as a certain stamping performance
3. Reflectivity: It has high reflectivity, making it a barrier against heat
4, the coating toughness is strong, galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage in transport and use.
Application
Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. The construction industry is mainly used for the manufacture of anti-corrosion industrial and civil building roof panels, roof grids, etc. The light industry uses it to manufacture household appliance shell, civil chimney, kitchen utensils, etc., and the automobile industry is mainly used to manufacture corrosionproof parts of cars. Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, meat and aquatic products frozen processing equipment, etc. Commercial mainly used as material storage and transportation, packaging tools,
