Key Product Features
- Excellent Corrosion Resistance: The zinc coating on galvanized steel provides sacrificial protection, while the color coating acts as a barrier against moisture, chemicals, and UV radiation.
- Weather Durability: Designed for outdoor exposure, the coated surface resists chalking, fading, and peeling under varied climatic conditions.
- Aesthetic Versatility: Available in a wide range of RAL colors, gloss levels, and custom finishes to match architectural and industrial design requirements.
- Formability and Adhesion: The coating maintains excellent flexibility, allowing bending, profiling, stamping, and roll-forming without cracking or delamination.
- Consistent Thickness and Width: Precise gage control ensures uniform thickness, and widths are customizable from 600mm to 1250mm to fit your production line.
- Batch Traceability: Each coil is marked with a unique batch number, and the corresponding mill test report verifies chemical composition, mechanical properties, and coating performance.
- 24-Month Warranty: We stand behind the quality of our coils, offering a two-year product warranty against coating defects and rust under normal usage conditions.
- Technical Support: Our engineering team assists with grade selection, color matching, forming recommendations, and installation guidance to maximize performance.

FAQ
1. What is the lead time for your galvanized color coated coils?
Our standard production lead time is around 15-25 days after order confirmation, depending on the specific thickness, color, and required quantity. Urgent orders can be accommodated through our rapid scheduling system, subject to production capacity.
2. Can I receive samples before placing a bulk order?
Yes, we can provide sample coils or small flat samples. Typically, free samples are available for existing colors; however, the buyer is responsible for shipping costs. You can contact our sales team to discuss sample requirements.
3. What colors and gloss levels are available?
We offer a full RAL color chart, as well as custom colors according to your provided reference sample. Gloss levels can vary from matte (30-40%) to semi-gloss or high gloss (70-80%), depending on the coating system.
4. How do you ensure the quality of each batch?
We follow ISO9001 quality control procedures. Every batch is tested for coating thickness, adhesion, impact resistance, pencil hardness, and zinc coating weight. A mill test report is issued for each batch and can be provided with the shipping documents.
5. What is your warranty coverage exactly?
The 24-month warranty covers defects in the coating such as peeling, chalking, or rust penetration under normal atmospheric conditions and proper usage. The warranty does not cover damage caused by mechanical abrasion, extreme chemical exposure, or improper installation.
6. Can the coil be custom cut? What about slitting or embossing?
We provide slitting services to narrow widths if required. Embossed (wood grain, linen, or diamond patterns) color coated coils are also available as an optional customization. Kindly specify your requirements in the inquiry.
7. What are the packaging and shipping details?
Each coil is wrapped with protective paper, plastic film, and steel-framed pallets or packaging to avoid edge damage and moisture ingress during transit. We ship from Qingdao port using standard sea freight. Container loading and export documentation are handled by our experienced logistics team.
8. How can I get technical support for my project?
Our technical engineers are available via email or video call. We can provide guidance on material selection, forming parameters, installation best practices, and finish compatibility. Just ask your sales representative for assistance.
