1. Q: What is the minimum order quantity (MOQ) for your anodized aluminum sheets/coils?
A:Our standard MOQ for anodized aluminum sheets/coils is [MOQ, 500 kg or 1 ton]. However, we understand project flexibility and offer competitive MOQs for new customers or specific colors/thicknesses. Contact us to discuss your requirements, and we'll strive to find a solution.
2. Q: What international quality standards do your anodized aluminum products comply with?
A:Our production strictly adheres to major international standards, including GB/T 5237.2-2017 (Voluntary Specification for Anodized Architectural Aluminum), and ISO 9001 (Anodizing of aluminium and its alloys). We also comply with RoHS and REACH regulations for environmental safety. Certificates available upon request.
3. Q: What thickness of anodic oxide film layer do you offer? Can it be customized?
A:We offer a wide range of anodic film thicknesses to suit different applications:
Architectural (Exterior): Typically 15-25 microns for superior weather resistance.
Decorative (Interior): Typically 5-15 microns for excellent appearance and moderate protection.
Hard Anodizing (Industrial): Up to 50+ microns for extreme wear and corrosion resistance.
Custom thicknesses within our technical capabilities are available. Please specify your needs.
4. Q: What color options are available? How consistent is the color batch-to-batch?
A:We offer a vast spectrum of standard colors (e.g., Clear/Silver, Champagne, Bronze, Black, Gold, various RAL colors). Our state-of-the-art coloring and sealing processes, combined with strict QC using spectrophotometers, ensure outstanding color uniformity and consistency within batches and from batch-to-batch. Pantone matching and custom color development are also possible.
5. Q: What is the salt spray resistance (corrosion resistance) of your anodized aluminum?
A:Our standard architectural anodized aluminum (15-25μm film) typically achieves over 1,000 hours neutral salt spray test (GB/NSS/ASTM B117)without significant corrosion or pitting. Hard anodized finishes offer even greater protection. Actual performance depends on film thickness, alloy, and sealing quality – we provide test reports.
6. Q: What aluminum alloy series do you commonly use for anodizing?
A:We primarily anodize high-quality 5xxx series (e.g., 5005, 5052, 5754) and 6xxx series (e.g., 6061, 6063, 6082)alloys. These alloys offer excellent anodizing characteristics, formability, strength, and corrosion resistance. We can advise on the best alloy choice based on your specific application (e.g., bending, welding, structural).
7. Q: Do you offer different types of anodizing finishes (e.g., gloss levels)?
A:Yes, we provide various surface finishes to meet aesthetic and functional needs:
Gloss Level: Clear/Silver (natural gloss), Matte/Satin (reduced glare), Brushed (textured).
Customization: Special-shaped parts can be anodized to meet the individual requirements of different products, and the appearance can be sandblasted, brushed, embossed, etc.
8. Q: What packaging do you use to ensure the anodized surface is protected during shipping?
A: We prioritize surface protection. Our standard packaging includes:
Protective plastic film or interleaving paper between sheets.
Sturdy wooden crates or reinforced plywood cases.
Edge protectors and corner guards.
Waterproof and shock-absorbent materials as needed.
Custom packaging solutions are available for fragile finishes or special logistics requirements.
9. Q: What is your lead time for anodized aluminum sheet orders?
A:Standard product lead times are typically [Standard Lead Time,7-15 working days]after order confirmation and receipt of deposit. Lead time depends on:
Order quantity and complexity.
Alloy and thickness availability.
Custom color/finish requirements.
We prioritize efficient production and provide accurate lead time estimates with each quotation.
10. Q: Can we request samples before placing a bulk order? What are the sample costs and lead times?
A: Absolutely! We strongly encourage sample evaluation. We offer **free standard color/finish samples for qualified inquiries (small freight charge may apply). Custom color/match samples are available at a reasonable cost. Sample lead time is usually [Sample Lead Time, 3-10 working days]. Contact us with your specifications to arrange samples.
