Pu Sandwich Metal Carved Wall Panel
The panels feature an independent, closed-cell structure that eliminates air convection heat transfer. The bottom aluminum foil forms a heat-reflective vapor barrier, and the surface metal plate blocks radiative heat transfer. These three layers combine to form a complete thermal insulation system, eliminating structural thermal bridging defects.

>95% Closed-Cell Ratio
The panels feature an independent, closed-cell structure that eliminates air convection heat transfer. The bottom aluminum foil forms a heat-reflective vapor barrier, and the surface metal plate blocks radiative heat transfer. These three layers combine to form a complete thermal insulation system, eliminating structural thermal bridging defects.
01
Dimensional Change Rate ≤1.5%
Even under high and low temperature cycling environments, there will be no shrinkage, cracking, delamination, or detachment. Unlike rock wool, whose thermal conductivity doubles after water absorption, and EPS, which suffers from long-term aging, powdering, and insulation failure, this panel maintains stable insulation performance for 25 years with no significant degradation.
02
Halogen-Free Flame-Retardant Formula
The polyurethane core material with a halogen-free flame-retardant formula is self-extinguishing upon contact with fire and produces no continuous dripping. Its low heat release rate significantly slows the lateral spread of flames.
03
Significant Sound Absorption
The standard thickness of a single-layer PU panel achieves an air-weighted sound insulation of 25~35dB, with a noise reduction coefficient of NRC≥0.85. Compared to simple sheet materials, it can effectively isolate outdoor traffic, equipment, wind, rain and noise

How to Choose the Surface Coating for pu sandwich metal carved wall panel in Coastal High-Salt-Spray Environments?
If you are located in a coastal environment, your building will be constantly exposed to salt, moisture, and ultraviolet radiation. Ordinary metal materials are prone to corrosion, rust, and coating aging. Therefore, in coastal projects, choosing the right surface coating is more important than simply choosing the wall panels.

How to avoid edge and corner damage during sea transport?
For international trade projects,pu sandwich metal carved wall panel typically involve multiple stages, including factory loading, domestic transportation, port loading and unloading, sea freight, and destination port delivery. Damage to edges and corners can affect installation efficiency and project schedule. Therefore, proper packaging and transportation solutions are just as important as product performance.
Use sturdy overall packaging
We will stack the wall panels neatly and evenly, wrapping each package with a moisture-proof film and using paper corner protectors, foam corner protectors, or metal corner protectors for edge protection to reduce collision damage during transportation.
Increase pallet support
We also use wooden or steel pallets for overall support, ensuring even stress and preventing the panels from bending or deforming due to unsupported force.
Reasonable control of stacking height
We control the number of stacking layers based on your order quantity. Stacking too high can increase pressure on the bottom panels, affecting the flatness and edge integrity of the panels.
Global Logistics and Payment Solutions
If you have no specific requirements regarding shipping speed, we will arrange for the transport of your pu sandwich metal carved wall panel via sea freight; the entire process typically takes about 14 days. Shipments originate from Jinan, Shandong Province, and we offer a variety of shipping routes-such as the Mediterranean and Malacca routes-for you to choose from. We are committed to ensuring the fastest possible delivery.
Regarding payment, we utilize a "30% deposit + 70% balance" Telegraphic Transfer (T/T) model. This approach effectively safeguards the interests of both parties: the deposit allows us to secure shipping capacity in advance and guarantee timely dispatch, while the balance payment upon delivery supports our ongoing operations. This collaborative model fosters long-term partnerships and ensures the smooth conduct of business between us.
