Product Introduction:
As a new material used for steel structure, the polyurethane roof panel has been the most suitable choice for many users. The PUF roof panel is divided into two types: The two waves of polyurethane composite roof panel, The three waves of PU foam composite roof panel. The characters of PU roof aluminum sandwich panels are heat insulation, waterproof, soundproof, and easy to install. The excellent function is the reason that so many people choice it as roof board.

Product Features:
1. The inner surface of panels sandwich can choose ordinary color steel plate or aluminum foil. Aluminum foil has corrosion resistance, moisture resistance, acid and alkali resistance, and the outer surface adopts color steel plate to ensure the overall structural strength of roof maintenance. With aluminum foil veneer, it is suitable for various corrosive environments that do not react with aluminum.
2. The unique design of waterproof tank can effectively prevent rainwater from infiltrating and avoid the phenomenon of cold bridges.
3. Exposed nails joint for convenient construction and installation.

Insulated sandwich panels with aluminum foil are the perfect building material for modern industrial buildings. They are sturdy and easy to install. They provide good insulation for temperature regulation, sound insulation and fire protection. Panel’s surface color coated steel shet are also customizable and price affordable !

Considerations for stacking sandwich panels with aluminum foil:
1. Be away from flames and must not be in contact with chemicals; It is advisable to store in a place protected from light and ventilation, avoid sunlight exposure, and take appropriate protective measures.
2. store on a solid, flat ground, the bottom should be paved with soft pads, and the spacing between the pads should not be greater than 1.5 meters; Remember not to use wooden pads.
3. bulk stacking shall not be higher than 1.5 meters, to prevent exposure and rain.
4. obvious signs should be set around the plate stack to avoid collision damage. Heavy objects and hard objects should not be placed on the plate stack to prevent scratching the plate surface. Stampede is strictly prohibited.

Application field:PUF sandwich panels are mainly used in the roofing and exterior walls of industrial plants and warehouses. In the past, industrial factories used prefabricated concrete slabs or asbestos slabs. With the rapid promotion of light steel structure, polyurethane aluminum sandwich panels have also replaced the above two materials with many significant advantages. While providing better thermal insulation effect, sandwich panels with mature and developed light steel structures can truly reflect a series of advantages such as light steel system lightness, fast efficiency and flexible layout, so it has become the preferred solution in single-storey plant buildings. For multi-storey industrial plants, in addition to the roof can be sandwich panel, the outer wall can also be flexibly arranged using PU sandwich board, and the purpose of beautifying the appearance of the building is achieved through the changeable color and shape of the color coating board. For industrial buildings with constant temperature and humidity requirements, the use of sandwich panels with better thermal performance than brick walls as enclosure materials can greatly save operating costs after completion.
