Product Description
Galvanized Steel Coil Products
Factory suppliers offering comprehensive range of DX51D, DX52D, DX53D, DX54D, S220GD, S250GD, S280GD, S350GD, S550GD, SGCC, SGHC, SGCH galvanized steel coils at competitive prices.
Product Overview
Galvanized coil consists of thin steel coil with a protective zinc layer applied through immersion in molten zinc bath. Manufactured primarily via continuous hot-dip galvanizing process, these coils offer superior corrosion protection and surface quality.
Production Process
Available in hot-rolled galvanized coil and cold-rolled hot-dip galvanized coil variants, using hot-rolled or cold-rolled steel strip as substrate. The zinc coating forms a strong bond with the substrate, ensuring excellent corrosion resistance and premium surface finish.
Performance Characteristics
- Corrosion Resistance: Zinc layer effectively isolates moisture and oxygen, significantly extending steel plate service life
- Processing Performance: Maintains steel plate strength and hardness while enhancing cold bending, welding, and stamping capabilities
- Wide Application: Suitable for construction, home appliances, automotive manufacturing, containers, and various industrial fields
Classification Standards
Categorized by performance into general use, mechanical bite, stamping, and other specialized types. Available in cold-rolled coil and hot-rolled pickled coil substrates. Coating weights range from Z60 to Z600 to meet diverse application requirements.
