Application of Zinc Coated Galvanised Iron Coil

Zinc coated galvanised iron coil products are mainly used in manufacturing industries, such as engineering construction, light industry, trolleys, agriculture, animal husbandry and fishery, and commercial services. among them:

The construction industry is suitable for the production of corrosion resistant industrial products and color steel roof sheets and color steel roof grids of industrial buildings;

The metallurgical industry uses it to produce household appliances, civil chimneys, kitchen supplies, etc.;

The automobile manufacturing industry is suitable for the production of anti-corrosion parts for automobiles;

Agriculture, animal husbandry and fishery are mainly used for food storage and transportation, and refrigerated production and processing supplies of meat and seafood, etc.;

Commercial services are mainly used for material supply, storage and packaging supplies.

Corrosion Resistance Principle of Zinc Coated Galvanised Iron Coil

Covering and isolation: Zinc reacts with oxygen to form a dense oxide film to isolate air and moisture and prevent oxidation of steel.

Cathodic protection: When the zinc layer is scratched somewhere, the surrounding zinc will first melt and become a substitute for iron to protect the bare steel from corrosion
