Frequently Asked Questions

1. What is your standard production lead time?

For standard specifications (EPS/PU/Rock Wool), the lead time is 7–14 days. Custom coatings or special core materials typically take 15–20 days.

2. Can you customize the panel length for container loading?

Yes. We recommend a maximum length of 11.8 meters for 40HQ containers. Panels can be cut to specific lengths to minimize onsite waste.

3. Do you provide technical support or installation drawings?

Absolutely. Our engineering team assists with CAD node design, wind load resistance calculations, and detailed installation manuals.

4. How do you package panels for ocean freight?

We use seaworthy export packaging: PVC protective film wrapping, stacked on steel or wooden pallets, and secured with straps to prevent surface scratches.

5. What international standards do your products meet?

Our panels are manufactured according to CE, ISO9001, and ISO14001 standards. SGS or ASTM fire and thermal test reports are available upon request.

6. Are the panels suitable for clean room applications?

Yes, our tongue-and-groove connection system is specifically designed for high-hygiene environments like medical facilities, food processing, and laboratories.
