Understanding Box Rib PU Composite Panel

What is the Box Rib PU Composite Panel?

These unique box rib sandwich panels get their name from the distinctive wavy design that resembles the Great Wall of China's shape. Made with durable galvanized and pre-painted steel sheets on both sides, they sandwich a special 5-ingredient polyurethane foam core that expands when heated to create super insulation. The PU foam is champion at blocking heat transfer and muffling sound - keeping cold spaces colder and hot spaces hotter while making refrigeration systems work more efficiently. The wavy rib design isn't just for looks; it actually makes the panels stronger and better at handling weather. Perfect for cold rooms, warehouses, and places where temperature control matters.

PU Composite Panel benefits

☆Wind-resistant defense system

The roof wall panels have strong resistance to positive and negative wind pressure. In order to solve the problem of concentrated wind pressure in the corners of the building, the fasteners are densely anchored to provide reliable protection for the building.

☆Excellent thermal insulation performance

The thermal insulation performance of polyurethane is 29 times that of masonry and 87 times that of ordinary concrete. The polyurethane core material forms a closed-cell structure through high-pressure continuous foaming, with extremely low water absorption, which can effectively hinder the penetration of water vapor, thereby exerting its excellent thermal insulation properties.

☆Quick assembly

The roof wall panels are prefabricated in the factory, and the modular design realizes "on-site installation". There is no need for on-site welding and complex cutting, which greatly shortens the construction time. It is particularly suitable for renovation projects with tight construction schedules.

☆Waterproof sealing

EPDM sealing strips are pre-installed at the overlap of the roof wall panels, and the eaves are equipped with a three-dimensional water guide groove. Through the stepped bite and self-draining structure, zero penetration is achieved in heavy rain conditions.

☆Fire safety

When encountering fire, the surface quickly carbonizes and cokes to form a fireproof isolation layer. After being compounded with the metal surface layer, the overall fireproof performance is improved to meet the fire resistance requirements of the building.

☆Sound insulation performance

Good sound insulation, can reduce noise interference by 20-30db, and effectively reduce the impact sound of rain, hail, etc.

☆Aesthetic function integration

The hidden nail connection system realizes the complete concealment of screws, and the flatness of the roof is greatly improved. The integrated design of the node decorative lines takes into account both practicality and modern aesthetics.

The Great Wall Board not only has a decorative effect, but also provides beautiful decorative effects and protection for buildings, while increasing artistic sense and visual appeal. It can also effectively protect the building surface, extend the service life of the building, maintain stability in different environments, and reduce maintenance costs. The unique design of the Great Wall Board makes installation relatively simple and quick, greatly improving work efficiency.In the future the building will have great architectural value.
