What is the thickness of the color plate?

Answer: Bao-steel brand color plate: 0.5mm, 0.6mm, 0.8mm. The Bao-steel brand is the best in China.

Other suppliers may use 0.326mm, and 0.426mm, not the Bao-steel brand, which is too weak.


For PU panels, the higher density the better insulation, right?

Answer: No. The best density is 42kg/m3. We can do the 42kg/m3 to ensure the best insulation.


If PU panel adds flame retardant, what will cause?

Answer: Flame retardant is bad material. It will cause dense smoke and poor insulation.

What is the warranty for the PU panels?

Answer: We can guarantee you 3 years warranty and design the PU panels used for 20 years. Compared with suppliers, some give 1 year warranty, some even have no warranty grantee.
