Galvanized Steel Coil Steel Strip
Superior Corrosion Resistance – The zinc coating effectively protects the steel from rust and oxidation, ensuring long-lasting durability.
Efficient Continuous Production – Manufactured through a continuous galvanizing process, galvanized coils offer stable quality and high production efficiency.
Wide Application Range – Ideal for construction, household, automotive, and industrial uses, meeting diverse market demands.
Cost-Effective and Reliable – Provides strong performance with minimal maintenance, making it a practical and economical material choice.
Galvanized coil is a thin steel plate with a layer of zinc adhered to the surface by immersing the thin steel plate in a molten zinc bath. Galvanized coils can be divided into hot-rolled galvanized coils and cold-rolled hot-dip galvanized coils,Galvanized steel strip is ordinary steel strip pickling, galvanized, packaging and other processes processed, because of good corrosion resistance, so widely used.

Large quantities of thin galvanized coils are used in automotive manufacturing, reefer containers, the construction industry, ventilation and heating installations, and furniture manufacturing. Galvanizing has become an important anti-corrosion method for steel, not only because zinc can form a dense protective layer on the surface of steel, but also because zinc has a cathodic protection effect. When the galvanized layer is damaged, it can still prevent the iron matrix through cathodic protection material corrosion.

Galvanized coils which are mainly used in construction, home appliances, automobiles, containers, transportation and household industries. Especially steel structure construction, automobile manufacturing, steel silo manufacturing and other industries.
Galvanized steel strip It is mainly used for making metal articles which are cold processed and no longer galvanized. For example: light steel keel, guardrail peach column, water tank, rolling door, bridge and other metal products.
