Frequently Asked Questions (FAQ)
1. What is the difference between 3003 and 5052 aluminum coil?
3003 is more formable and weldable, while 5052 offers higher strength. For most architectural and light industrial applications, 3003 H24 provides an excellent balance of workability and corrosion resistance.
2. Can you provide the coil in a different width or thickness?
Yes, we offer customization. Please contact us with your specific requirements. Standard widths range from 1000mm to 1500mm, and thicknesses from 0.5mm to 3.0mm (subject to minimum order quantity).
3. Is the coil surface suitable for painting?
The mill finish surface is clean and can be painted or coated after proper pretreatment. We also offer pre-painted options upon request.
4. What is the minimum order quantity (MOQ)?
For standard sizes, the MOQ is 1 ton. For customized lengths, the MOQ may vary; please inquire with our sales team.
5. How is the coil packaged for export?
Each coil is wrapped with waterproof paper, plastic film, and steel strapping, then placed on a wooden pallet or in a crate to ensure safe transportation.
6. What is the typical lead time for this product?
For standard sizes, lead time is 7-15 days after order confirmation. Custom orders may take 20-30 days depending on quantity and specifications.
7. Do you provide samples? Are they free?
Yes, we can provide samples (A4 size or 1m length) for quality evaluation. Samples are free, but the freight is collect or negotiable.
