FAQ

 

Q: Can you provide the K-value calculation for my truck body?

A: Yes, our engineers can provide theoretical K-value calculations based on the panel thickness and vehicle dimensions.

Q: Do you support CKD kits for Isuzu or Hino chassis?

A: Absolutely. We have a database of standard chassis dimensions and can provide a "Plug & Play" panel kit.

Q: How do you ensure the foam is even inside such a large panel?

A: We use high-pressure continuous foaming lines or large-scale vacuum presses to ensure consistent density and zero voids.

Q: Can you provide CKD (Completely Knocked Down) kits?

A: Yes, we specialize in providing full-set panels including extrusions and adhesives for local assembly, reducing your shipping costs.

Q: Are your panels waterproof?

A: Yes. The closed-cell PU foam structure provides excellent moisture resistance and low water absorption.

Q: Can you customize panel sizes?

A: Yes. We provide customized panel dimensions according to truck body size and project requirements.

Q: Do you support OEM manufacturing?

A: Yes. We support OEM production, private label manufacturing, and customized refrigerated truck body solutions.
