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 superior corrosion resistance, especially in acidic or salty environments. It also provides better heat reflectivity and a longer service life compared to standard galvanized (GI) coatings. -
Can you supply coils with a thickness other than 0.35mm?
Yes, we offer a range of thicknesses from 0.2mm to 1.2mm. The 0.35mm thickness is a popular choice for applications requiring lightweight strength. Please contact us for other thickness options. -
What colors are available, and can you match a specific RAL color?
We offer a wide selection of standard RAL colors, as well as custom color matching. For small MOQ orders, we can produce according to your color sample or RAL code. Minimum order quantity for custom colors may apply. -
Is your product suitable for outdoor use in coastal areas?
Yes, the AZ150 coating provides excellent resistance to salt spray and humidity, making it ideal for coastal environments. For extreme conditions, we recommend using a PVDF paint system for enhanced UV and chemical resistance. -
What is the minimum order quantity (MOQ) for this coil?
Our standard MOQ is 20 tons per size and color. However, we can accommodate smaller trial orders for new customers. Please discuss with our sales team for details. -
Do you provide samples before bulk order?
Yes, we can provide free samples (A4 size or 20x20cm) for quality evaluation. The courier cost is borne by the buyer, and samples are typically dispatched within 3-5 working days. -
How is the coil packed for export?
Our standard packing includes anti-rust paper, plastic film, steel strapping, and wooden pallet or steel skid. For sea transport, we use moisture-proof and shock-proof packaging to ensure the product arrives in perfect condition. -
What is the lead time for production?
For standard specifications, the lead time is approximately 15-20 days after receiving the deposit. For custom colors or special coatings, it may take 20-30 days. We always strive to meet your delivery schedule.
