Product Overview: 200-type 28mm Aluminum Alloy Insulated Sandwich Panel

Developed specifically for high-end roofing and building cladding systems. It is made of double-sided aluminum alloy sheets and a high-density polyurethane core material, offering advantages over traditional steel sandwich panels, including lighter weight, corrosion resistance, superior insulation performance, and longer service life.Standard Colors: Coffee, Gray; Custom color schemes available.Core Advantages:

• Superior Corrosion Resistance: The aluminum alloy surface effectively resists rainwater erosion, salt spray, and acid/alkali corrosion, making it perfectly suited for harsh corrosive environments such as coastal areas, humid environments, and chemical plants.
• Lightweight and High-Strength: Lighter than steel sheets while maintaining excellent bending and compressive strength, reducing overall roof load and structural investment costs.
• Superior Thermal Insulation Performance: The polyurethane core material provides excellent thermal insulation, reducing building energy consumption for air conditioning and heating.
• Convenient Installation: Neutral-size modular design, snap-fit ​​splicing structure, tight joints, good waterproofing, and rapid on-site assembly, shortening the construction cycle.

Excellent fire resistance: With a flame retardant rating of up to B1, it effectively suppresses the spread of fire and meets the fire protection requirements of conventional buildings.

Application Scenarios：

Primarily used in projects requiring high thermal insulation and heat preservation, such as large-span factory roofs, coastal buildings, leisure sunrooms, outdoor awnings, villa roof renovations, construction in chemical and marine corrosive environments, and prefabricated buildings
