Dx51D Dx52D Galvanized Sheet Coil
Excellent Corrosion Resistance – The zinc coating formed through the hot-dip process provides a strong protective barrier, significantly extending the service life of the steel by preventing rust and surface damage.
Wide Industrial Applications – Galvanized coils are highly versatile and used across multiple industries, including construction, automotive, household appliances, containers, and transportation, making them a reliable material choice.
High Strength and Durability – Combining the mechanical properties of steel with the added protection of zinc, galvanized coils deliver superior strength and durability, ensuring consistent performance in demanding environments.
Cost-Effective and Low Maintenance – With their long-lasting protective layer, galvanized coils reduce the need for frequent repairs or replacements, providing both economic and practical benefits for manufacturers and end users.
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, 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 Coil Coating:
(1) Normal spangle coating
During the normal solidification process of the zinc layer, the zinc grains grow freely and form a coating with an obvious spangle shape.
(2) Minimized spangle coating
During the solidification process of the zinc layer, the zinc grains are artificially restricted to form the smallest possible spangle coating.
(3) Zinc-free coating
The coating obtained by adjusting the chemical composition of the plating solution has no visible spangle morphology and a uniform surface.
(4) Zinc-iron alloy coating
Heat treatment of the steel strip after passing through the galvanizing bath to form an alloy layer of zinc and iron throughout the coating. A coating that can be painted directly without further treatment other than cleaning.
(5) Differential thickness coating
For both sides of galvanized steel sheet, coatings with different zinc layer weights are required.
(6) Smoothing
Skin-passing is a cold-rolling process performed on galvanized steel sheets with a small amount of deformation for one or more of the following purposes.
Improve the surface appearance of galvanized steel sheet or be suitable for decorative coating; make the finished product not see the phenomenon of slip line (Lydes line) or crease during processing to minimize temporarily, etc.
Galvanized sheet (coil) strip products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.; the light industry industry uses it to manufacture household appliance shells, civil chimneys, kitchen utensils, etc., and the automotive industry is mainly used to manufacture corrosion-resistant parts for cars, etc. ; Agriculture, animal husbandry and fishery are mainly used for food storage and transportation, meat and aquatic products freezing processing tools, etc.;
