Product Parameters

galvanized coils

Strong corrosion resistance: The zinc layer on the surface can effectively isolate air and moisture, prevent the external oxygen, moisture and chemicals from corroding the steel plate, and can remain uncorroded for a long time even in harsh environments such as humidity, acid and alkali. Good processing performance: It can be processed by bending, stamping, stretching, welding and other methods, which can meet the production needs of various complex shapes of parts in different fields. High strength: After hot-dip galvanizing and other treatments, the strength and hardness of the galvanized coil are improved to a certain extent, and it can withstand greater pressure and impact.

FAQ

A:What is the service life of galvanized coil?

B:The service life of galvanized coil depends on the thickness of zinc layer and the use environment. In conventional outdoor environments, hot dip galvanized coils with thick zinc layers can be used for 20-50
years.

A:What are the main advantages of galvanized coil?

B:The main advantages of galvanized coils are corrosion resistance, long life, high strength, and better decorative and protective properties can be obtained by coating or processing.

A:What are the disadvantages of galvanized coil?

B:Under high temperature conditions, the zinc layer of galvanized coil will deteriorate and the oxidation resistance will decrease. In addition, the zinc layer can also be damaged by long-term wear or contact with acidic substances.

A:Is galvanized coil suitable for high temperature environments?

B:Galvanized coil is not suitable for high temperature environment, when the temperature exceeds 200ºC, the zinc layer is prone to oxidation, long-term exposure to high temperature will affect its corrosion resistance.

A:How is the environmental performance of galvanized coil?

B:The galvanized coil has good environmental performance, and the zinc layer can extend the service life of the steel and reduce the frequency of replacement. At the same time, the waste galvanized coil can also be recycled to reduce the waste of resources.

A:What are the precautions for the storage of galvanized rolls?

B:Galvanized coil should be stored in a dry, ventilated environment to avoid contact with water, acid, alkali and other corrosive substances. When storing, try to avoid stacking directly to prevent crushing
the zinc layer.
