Product Specification
Galvanized Steel Coil, a cornerstone product in modern manufacturing, is produced through a continuous hot-dip galvanizing process where steel sheet is immersed in a bath of molten zinc. This creates a tightly-bonded zinc-iron alloy coating on both surfaces, providing robust and long-lasting sacrificial protection against corrosion. Supplied in coil form, it offers superior economic efficiency in handling, storage, and subsequent high-speed processing. By combining the strength and formability of steel with the protective properties of zinc, it serves as a vital raw material for a multitude of industries, including construction, automotive, and appliance manufacturing, and is also the primary substrate for painted/coated products.
| Parameter | Description / Typical Range |
|---|---|
| Base Steel Grade | Commercial Quality (CQ), Structural (SQ), Forming (FQ), High Strength Low Alloy (HSLA). Common grades: DX51D, DX52D, S220GD, S350GD (EN), ASTM A653 Gr. 40, 50, 80. |
| Coating Type | Hot-dip Galvanized (HDGI). |
| Zinc Coating Mass | Expressed as total coating mass (both sides) in g/m² or oz/ft². Common designations: Z60 (G60), Z90 (G90), Z120, Z180, Z275 (G90). Higher numbers indicate thicker zinc layers. |
| Steel Thickness | 0.25 mm to 6.0 mm (commonly 0.4mm - 3.0mm). |
| Coil Width | 600 mm to 2000 mm (standard industrial range). |
| Coil Weight | 5 to 25 Metric Tons (typical). Coil ID: 508mm or 610mm. |
| Surface Finish | Regular spangle, Minimal spangle, Smooth/Extra-smooth (skin-passed). |
| Surface Treatment | Chromate passivation (Cr-free options available), Oiled, or Phosphated for enhanced paint adhesion or storage. |
| Mechanical Properties | Yield Strength: 140 MPa to 550 MPa+. Tensile Strength and elongation vary by grade and temper (e.g., CR4, CR8). |
| Primary Standards | ASTM A653, EN 10346, JIS G 3302, GB/T 2518. |
Primary Applications:
Construction & Infrastructure:
Roofing & Walling Systems: As the base metal for corrugated sheets, standing seam roofs, and composite panels.
Structural Framing: Purlins, girts, studs, and tracks (after roll-forming).
Garage Doors, Rainwater Systems, and HVAC ductwork.
Automotive Industry:
Body Panels & Structural Parts: Used for underbody components, interior reinforcements, brackets, and shields where corrosion resistance is critical.
Appliance & Home Electronics:
Housings & Casings: For refrigerators, washing machines, air conditioners, and computer chassis.
Internal Components: Back panels, frames, and mounting brackets.
Industrial & General Manufacturing:
Electrical Enclosures: Switchboards, control boxes, and cable trays.
Agriculture: Grain silos, animal pens, and equipment panels.
Storage & Furniture: Shelving units, lockers, and filing cabinets.
Key Advantages:
Exceptional Corrosion Resistance: The zinc coating provides reliable sacrificial (cathodic) protection, safeguarding the steel even at cut edges or scratches.
Long Service Life & Low Maintenance: Dramatically extends the lifespan of steel products, reducing maintenance and replacement costs over time.
Cost-Effectiveness: Offers the most economical and proven method for achieving long-term steel corrosion protection for a vast range of applications.
Excellent Formability & Fabrication Friendly: Can be easily cut, stamped, roll-formed, and welded (with proper techniques), making it ideal for high-volume manufacturing.
Versatile Substrate: The ideal and most common base material for further processing such as painting (e.g.,彩涂卷) or lamination.
Sustainable Material: Steel is 100% recyclable without loss of properties, and the zinc coating is a naturally occurring element, contributing to a circular economy.
