Colored stone-patterned PU sandwich panels are a type of composite building material, made by bonding double-sided color-coated steel sheets (with a stone-patterned decorative film on the surface) to a rigid polyurethane (PU) foam core through high temperature and pressure. Its stone-patterned surface uses a simulated film coating technology to mimic the texture of natural stone, combining decorative and functional properties, and is widely used in building envelope systems. The product integrates lightweight, thermal insulation, fire safety, and rapid installation characteristics, making it an ideal material for industrial and civil buildings.

The core advantages of Colorful Stone Pattern PU SandwichPanels for Exterior Wall are:
1. Decorative and Aesthetic Appeal: The stone-textured coating provides a realistic stone visual effect with rich colors (such as wood grain, limestone, granite, etc.), meeting the aesthetic needs of modern architecture.
The surface is highly durable; the weather-resistant coating can maintain its vibrant color for 10-15 years, with low maintenance costs.
2. Superior Thermal Insulation Performance: The PU core material has a low thermal conductivity (λ≤0.023 W/(m·K)), far superior to traditional building materials, effectively reducing building energy consumption.
The closed-cell structure is moisture-proof and seepage-proof, suitable for high-humidity environments (such as cold storage and coastal buildings).
3. High Safety and Fire Resistance: The PU core material, after flame-retardant treatment, can achieve a B1 fire rating; some upgraded versions of composite rock wool can be upgraded to an A2 non-combustible rating.
It does not melt or drip when exposed to fire, slowing the spread of fire.
4. Lightweight, Efficient, and Easy to Install: Weighing only 10-14 kg/㎡, it reduces building load and lowers structural costs.
Utilizing tongue-and-groove or snap-fit joints and modular assembly, construction efficiency is increased by 40% compared to traditional building materials.
Flat Metal Siding Wood Grain with Grooves Sandwich Panel application scenarios and application cases
1. Industrial and Logistics Sector
Factory/Warehouse: Utilizing lightweight and high-strength properties to achieve large-span structures; thermal insulation regulates indoor temperature and humidity, reducing energy consumption.
Cold Chain Logistics: Moisture-proof and thermal insulation performance ensures temperature stability in cold storage and refrigerated truck compartments.
2. Commercial and Public Buildings
Shopping Malls/Exhibition Halls: Stone-textured surfaces enhance the spatial quality, used for partitions, ceilings, and curtain walls.
Gymnasiums/Airports: Fire safety and sound-absorbing designs meet safety regulations for large public spaces.
3. Special Needs Scenarios
