1、Bingfa Steel Structure produces excellent polyurethane sandwich wall panels for metal structures, fabrication facilities, storage facilities, refrigeration units, pre-engineered structures, commercial facilities, and industrial wall covering applications. Our urethane sandwich wall panels are constructed with two color coated metal sheets encasing a polyurethane insulation core providing excellent insulation values, lightweight structure, clean appearance, and quick installation. 2、PU sandwich panels are developed and designed for interior and exterior wall systems. Projects that require proper temperature insulation systems and require quick construction methods together with quality wall construction can use PU sandwich panels for their construction needs. You can select any other dimension such as panel thickness, length, steel sheet thickness, surface color, and joint design which can also be manufactured as per your own building requirements.
1.Excellent Thermal Insulation The polyurethane core provides strong insulation performance, helping reduce heat transfer through wall systems and improve indoor temperature stability.
2.Durable Wall Cladding System Color-coated steel sheets provide a clean surface, strong enclosure performance, and long-lasting wall protection for steel warehouses, workshops, and industrial buildings.
3.Lightweight and Easy to Install PU sandwich wall panels are lightweight and prefabricated, making transportation, handling, and on-site installation faster and more efficient.
4.Suitable for Exterior and Interior Walls The panels can be used for exterior wall cladding, interior partition walls, cold room walls, prefab building walls, and industrial enclosure systems.
5.Custom Size, Color, and Joint Design Panel thickness, length, surface color, steel sheet thickness, and connection method can be customized to match your project design and budget.
Projects will find great use for the PU sandwich wall panels because they provide insulation; have a smooth wall surface; and will require fast construction time.

The structure combines the strength of metal with polyurethane insulation, creating an ideal wall system for steel building applications and building prefabricated structures.
PU sandwich wall panels are a good choice of application in steel building projects that require solid insulation, clean look at the wall and easy way to install it as well. In terms of the indoor climate, the PU sandwich wall panel has the ability to enhance the indoor climate to be better. The PU sandwich wall panel acts as a good insulator, reducing the heat that is transferred through the wall. In addition, the installation creates a stable enclosure system that can be utilised for warehouses, workshops, cold rooms and industrial structures.
Prefab wall panels also speed up the building process. With a good joint design and the right trims, fasteners and seals, there are many building projects where PU insulated wall panels will provide a good, long-lasting wall solution.
Our sandwich panel production process is carefully controlled to ensure accurate dimensions, strong bonding, and consistent panel quality.
Steel Coil Uncoiling
Color-coated steel coils are loaded onto the uncoiling machine, leveled, and continuously fed into the production line. Protective film may also be applied to reduce scratches and surface damage.
Steel Sheet Roll Forming
The upper and lower steel sheets pass through roll-forming equipment to create the required panel profile, surface pattern, and edge shape.
Core Material Feeding
Rock wool or other insulation core materials are transported into the production line according to the required panel thickness and specification. The core is positioned carefully to maintain consistent panel structure.
Adhesive Application & Edge Sealing
Adhesive is applied evenly between the metal sheets and insulation core to create a stable bond. Panel edges may also be formed or sealed according to the selected joint design.
Double-Belt Pressing & Automatic Cutting
The metal sheets and core material pass through the double-belt pressing system, where they are continuously bonded and formed. The finished panels are then automatically cut to the required project length.
Finished Panel Stacking & Packaging
The completed panels are inspected, stacked, labeled, and packed with protective materials. Proper packaging helps protect panel surfaces and edges during storage, container loading, and delivery.

FAQ About PU Sandwich Panels
Q：Where are PU sandwich wall panels used?
A：Steel warehouses, workshops, cold rooms, and food processing buildings are common uses for PU sandwich wall panels as are commercial buildings, prefab houses and provide interior partition walls.
Q：Can PU sandwich wall panels be customized?
A：Panel thickness, Length, Thickness of Steel Sheet, Color, Surface Profile, and Joint Design can be customized to meet your Project Requirements.
Q：Are PU sandwich panels suitable for cold rooms?
A：Indeed, the PU sandwich wall panel is perfect for use in both cold storage and temperature-controlled facilities because of the polyurethane core of the panels, which gives excellent thermal insulation.
