FAQ

Q: What are the main types of cold storage panels? Which is the best?
A: The main types are Polyurethane (PU), Polystyrene (EPS), and XPS. Polyurethane (PU) sandwich panels are considered the best overall, widely used in medium and large cold storage facilities. They offer superior insulation with a very low thermal conductivity (as low as 0.018-0.024 W/(m·K)), making them the top choice for efficiency.

Q: How do I choose the right thickness for my temperature needs?
A: Thickness depends on your target temperature:

Fresh Storage (above -5°C): Typically 100mm.
Cold Storage (down to -25°C): Typically 150mm.
Freezer Storage (down to -35°C & below): 150mm or thicker (e.g., 200mm).

Q: What do the B1 and B2 fire ratings mean?
A: These are Chinese standards for flame resistance.

B2 Grade: Flammable but self-extinguishing. It stops burning shortly after a flame is removed.
B1 Grade: Flame-retardant. Harder to ignite, offering better fire safety.

Q: What is the difference between the metal surfaces (e.g., color steel, stainless steel)?
A:Color Steel: The most common choice. Cost-effective with good rust resistance.
Stainless Steel: Offers excellent corrosion and rust resistance, ideal for humid or high-hygiene environments, but is more expensive.

Q: Can I order custom sizes?
A: Yes. Panels can typically be customized in length and width to fit your project. Common thickness options include 50mm, 75mm, 100mm, 120mm, 150mm.
