Our prepainted galvanized coil is a composite material that combines the strength of cold-rolled steel, the protective power of a zinc layer, and the aesthetic versatility of a paint finish. The SPHC base material offers excellent forming characteristics, making it easy to process into profiles, panels, and components. The SGCC grade is also available for applications requiring higher strength and ductility. The Z100 zinc coating ensures effective sacrificial protection, preventing rust formation even if the paint surface is scratched or slightly damaged.
The paint system used in our prepainted coil is carefully selected for outdoor durability. It resists UV rays, moisture, and chemical pollutants, maintaining its color and gloss for an extended period. This makes the coil ideal for building materials such as roofing sheets, wall cladding panels, corrugated sheets, and sandwich panel outer layers. Additionally, the coil can be used in the production of home appliances, air conditioner casings, refrigerators, washing machines, and various electronic enclosures where both appearance and durability are essential.
One of the key advantages of our product is the versatility in thickness. The 0.4mm coil is lightweight and economical, perfect for applications where weight savings matter, such as interior partitions or lightweight roofing. The 1.0mm coil provides a balanced combination of strength and formability, suitable for general construction and structural use. The 1.2mm coil delivers higher rigidity and load-bearing capacity, making it a reliable choice for industrial roofing, heavy-duty wall panels, and load-bearing components.
For customers who require a specific RAL color, we offer a wide spectrum of shades, including warm reds, cool blues, neutral grays, and many others. Our factory uses precise color matching systems to ensure batch-to-batch consistency. If you have a custom color code or a sample, we can produce the coil according to your specification. The paint thickness and gloss level can also be adjusted to match your requirement.
The coil is packaged with anti-rust paper, steel straps, and protective edge rings to ensure safe transportation. We export through Qingdao port, using standard sea-worthy packaging suitable for long-distance shipping. Our team ensures that every coil is inspected before shipment, verifying thickness, zinc coating weight, paint adhesion, and color uniformity.

What is the difference between SPHC and SGCC base materials?
SPHC is a hot-rolled steel grade with good forming properties, while SGCC is a hot-dip galvanized steel grade. Both are suitable for prepainted coils; the choice depends on your specific application and required strength. We can supply either base material according to your needs. -
Can you provide custom RAL colors?
Yes, we support custom RAL colors. If you have a specific color code or a physical sample, our factory can match it precisely. Standard RAL colors are also available with fast delivery. -
Is the Z100 zinc coating sufficient for outdoor use?
Z100 (100g/m²) provides reliable corrosion resistance for many outdoor applications. For highly corrosive environments, we can offer higher zinc coating weights such as Z120, Z180, or Z275 upon request. -
What surface finishes are available?
We offer smooth, embossed, or matte finishes, as well as different paint types such as polyester (PE), silicone-modified polyester (SMP), or polyvinylidene fluoride (PVDF) depending on your durability requirements. Please indicate your preference when inquiring. -
Do you provide sample rolls for testing?
Yes, we can provide small sample strips or a partial coil for trial purposes. Please contact our sales team to discuss sample availability and shipping costs. -
How is the coil packaged for export?
Each coil is wrapped with moisture-proof paper, plastic film, and steel straps, with edge protection to prevent damage during handling and shipping. We export via Qingdao port with standard sea-worthy packaging. -
Can the coil be cut into specific widths?
Yes, we can slit the coil into custom widths according to your drawings or specifications. Minimum width is typically 600mm, but we can discuss special requirements. -
What is the minimum order quantity?
Our standard MOQ is 50 to 100 tons, depending on thickness and color. For trial orders or special colors, we can negotiate a smaller quantity on a case-by-case basis.
