Types of PU Sandwich Panels

PU sandwich panels are divided into roof panel systems and wall panel systems according to their uses.

Roof panel system: commonly used hidden nail PU roof panels and four-wave corrugated roof panels.
Wall panel system: commonly used small corrugated PU sandwich panels, medium groove PU sandwich panels, and pure flat PU sandwich panels.

Advantages of PU Metal Sandwich Panels

Performance advantages

Polyurethane foam has low thermal conductivity, can effectively block heat transfer, and has good thermal insulation performance.
The metal panel on the surface of the PU sandwich panel can block water, and the polyurethane core material is a closed-cell structure (closed-cell rate ≥ 90%), which is highly waterproof and moisture-proof.
PU core material can reach B1 level (flame-retardant) or higher level fire protection standards by adding flame retardants, and has good fire resistance.

Structural and construction advantages

The thickness of metal sandwich panels is relatively thin, the density of the core material is also low, the overall weight is light, and the metal panel has strong compression and bending resistance.
The surface metal panel can be customized with different colors and patterns, which has good decorative properties.
PU metal sandwich panels are modular in design and can be installed by splicing, which is quick and efficient.

PU Sandwich Panel Application

Used for wall and roof systems of industrial plants, warehouses, workshops, and logistics centers.
In clean workshops in the electronics, pharmaceutical, and food processing industries, PU sandwich panels can meet the needs of dust-free environments, and the joints are well sealed.
PU metal sandwich panels are often used to make facilities such as cold storage, refrigerated vehicles, and refrigerated containers.
Used to manufacture prefabricated buildings with modular designs, such as expandable container houses, folding houses, modular houses, etc.
PU metal sandwich panels can also be used to make billboards and noise barriers.
