Welcome to Hemaokang Steel (Shandong) Co., Ltd. — your professional partner for high-quality steel products. Our Galvanized Color Coated Coil is precisely engineered for roofing sheets, sandwich panels, and corrugated rolling, combining structural strength with an attractive finish. With a thickness of 0.35mm, this coil is ideal for a wide range of construction applications, offering reliable performance and long-lasting aesthetics.
As a manufacturer from Liaocheng, Shandong, we take pride in our advanced production lines and strict quality management system. Our coil is produced using hot-dip galvanized steel as the base, followed by a uniform color coating process. The result is a product that resists corrosion, maintains color stability, and performs consistently in various climates. Whether you need a single coil or a bulk shipment, we are ready to support your project with flexible customization and dependable delivery.
Key Features & Benefits:
- Superior Corrosion Resistance: The hot-dip galvanized substrate provides a sacrificial protection layer, while the top color coating acts as a barrier against moisture, chemicals, and UV radiation.
- Excellent Formability: Designed for corrugated rolling and sandwich panel production, the steel coil offers stable mechanical properties that support precise bending, stamping, and profiling.
- Color Retention: The high-quality paint system resists fading, chalking, and peeling, keeping roofs and panels looking new for years.
- Lightweight yet Strong: At 0.35mm thickness, this coil is light enough to reduce the load on building structures while providing adequate strength for roofing and cladding applications.
- Eco-Friendly Option: Steel is 100% recyclable, and our production process adheres to responsible manufacturing practices.
- Customized Width and Color: We offer flexible dimensions and a wide range of RAL colors to meet your specific design and installation requirements.

Why Choose Our 0.35mm Galvanized Color Coated Coil?
The 0.35mm thickness is a popular choice for roofing and sandwich panel applications because it strikes an ideal balance between strength, weight, and cost. Our coil is manufactured under strict process control, ensuring consistent gauge, uniform coating thickness, and flat surface appearance. It performs well in corrugated rolling machines and can be easily formed into various profiles without cracking or delamination. This saves your production time and reduces waste, ultimately increasing your operational efficiency.
For sandwich panels, the smooth and uniform color coating enhances the bonding between the metal sheet and the core material, providing excellent adhesion and panel rigidity. For corrugated roofing sheets, the coated surface offers high resistance to weathering, rust, and impact. Whether you are a roofing sheet manufacturer, a sandwich panel producer, or a building contractor, this coil is a solid solution that delivers consistent results.

Our MOQ is generally 50 tons for standard sizes. However, for customized widths or colors, a higher quantity may be required. Please contact us for detailed terms.
2. Can I get samples before placing a bulk order?
Yes, we provide sample coils (usually 1-2 meters long) at a nominal cost. The sample cost will be deducted from the final order invoice once you confirm a bulk purchase.
3. What colors are available?
We offer a wide range of RAL colors, including red, blue, green, white, grey, and dark brown. Custom color matching is also available upon request.
4. How long does the color coating stay without fading?
The longevity depends on the paint system (PE, HDP, PVDF) and the local climate. PE offers standard performance, while PVDF provides excellent UV stability. Life expectancy can range from 10 to 25 years under proper conditions.
5. Can the coil be cut to custom widths?
Yes, we can slit the coil to various widths as per your requirement. Common widths range from 600mm to 1250mm, but we can accommodate special sizes based on your machinery.

Absolutely. Our 0.35mm coil is specifically designed for corrugated sheet forming and also works well with sandwich panel lines. Its mechanical properties ensure smooth feeding and accurate profile shaping.
7. How do you pack the coils for export?
Each coil is wrapped with moisture-proof paper, plastic film, and steel strapping. The coils are then fixed on horizontal or vertical packing frames for container loading, ensuring safe transit.
8. What is the production lead time?
For standard sizes and regular colors, production usually takes 15-20 days after receiving the deposit. Customized orders may take 25-30 days depending on the complexity.
