Frequently Asked Questions (FAQ)

What is the difference between AZ150 and regular galvanized coating?
AZ150 is an aluminum-zinc alloy coating (55% Al, 43.5% Zn, 1.5% Si) that offers significantly better corrosion resistance and heat reflectivity compared to traditional galvanized (pure zinc) coatings. It can last 2–4 times longer in harsh environments.
Is this sheet suitable for coastal or high-humidity areas?
Yes, the AZ150 coating and color topcoat provide excellent protection against salt spray and moisture. For extreme coastal environments, we recommend a PVDF paint system for enhanced durability.
What colors are available?
We can produce any RAL color upon request. Standard colors include white, red, dark blue, grey, and green. Minimum order quantity may apply for custom colors.
Can I get a sample before placing a bulk order?
Certainly. We provide free samples (courier cost paid by customer) for quality evaluation. Please contact our sales team with your requirements.
How is the sheet packaged for export?
Sheets are packed in steel pallets with waterproof paper and plastic wrapping, or in wooden crates as requested. Edge protection and corner guards are used to prevent damage during transit.
What is the minimum order quantity (MOQ)?
For standard colors and sizes, MOQ is typically 50 tons. For custom colors or special profiles, MOQ may be higher. We can discuss based on your project volume.
Does the sheet meet ASTM A755 standard?
Yes, our product is manufactured in full compliance with ASTM A755/A755M, covering both the metallic coating and paint coating requirements. Test reports are available upon request.
How long is the delivery time?
Lead time is generally 15–25 days after receipt of deposit, depending on order quantity and customization. We can provide a more accurate schedule after order confirmation.
