Frequently Asked Questions (FAQ)
1. What core materials are available for your sandwich panels?
We offer polyurethane (PU), mineral wool, rock wool, EPS, and XPS cores. Each has distinct thermal, fire, and acoustic properties. PU provides the best insulation, while mineral wool gives top fire resistance. We can help you choose based on your project needs.
2. Can I get a free sample before placing a bulk order?
Yes, we provide free samples of our metal exterior wall sandwich panels. You only need to cover the shipping cost. The sample will be a standard size (e.g., 200mm x 200mm) so you can inspect the material, coating, and finish.
3. What is the minimum order quantity (MOQ)?
Our MOQ is typically 500 square meters for standard panels, but we can accommodate smaller orders for custom projects. Contact our sales team for details.
4. How long does the production take?
Production time depends on the order quantity and customization. For a standard 10,000 sqm order, lead time is approximately 15–20 working days. Custom colors or lengths may require additional time.
5. Do you provide technical support for installation?
Absolutely. Our 24/7 technical support team can assist with installation guidelines, detailed drawings, and on-site troubleshooting. We also offer installation manuals and videos upon request.
6. Are your panels fire-rated?
Yes, depending on the core material. Mineral wool and rock wool panels achieve Class A (non-combustible). PU panels can be manufactured to meet B1 or B2 fire ratings per local regulations. Please specify your requirement when ordering.
7. What colors and finishes are available?
We offer a wide range of RAL colors. Standard finishes include PVDF (high durability, ideal for coastal areas), PE (economical), and HDP (high-performance). Other custom coatings can be arranged.

Our factory is ISO9001 certified. We conduct raw material inspection, in-process monitoring, and final product testing (including flatness, adhesion, and thermal performance). Each batch is accompanied by a quality certificate.
