Composite Sandwich Panel

Product Details

Composite sandwich panel is a high-performance building enclosure panel that uses advanced “sandwich” composite structure to firmly bond high-strength surface layer and high-quality core material through continuous automated production line. This product integrates load-bearing, insulation, and decoration, making it an ideal choice for modern industrial plants, warehousing and logistics, commercial buildings, and clean workshops.

Product Structure and Materials

Surface layer/panel:

High quality aluminum zinc or galvanized color steel plates are used, with high-performance coatings (such as PVDF, HDP, PE) applied to the surface, providing excellent weather resistance, corrosion resistance, and a wide range of color options.

The thickness is usually 0.4mm-0.8mm, and can be customized according to the requirements of load-bearing and wind pressure resistance.

Core material:

• Polyurethane (PU) core material: with extremely low thermal conductivity, the best insulation performance, and a fire rating of up to B1.
• Rock wool (RW) core material: A-grade non combustible material with excellent fire resistance and good insulation and sound insulation effects.
• Glass wool (GW) core material: lightweight, good insulation and sound absorption performance, economical and practical.
• Other core materials: XPS, EPS and other core materials can also be provided according to specific needs.

Adhesive and Composite Technology:

Using high-performance environmentally friendly adhesives, composite through continuous hot pressing or cold pressing processes to ensure high bonding strength between the surface layer and the core material, without hollowing or delamination.

Characteristics of Composite Sandwich Panels

Excellent thermal insulation: Especially with PU and rock wool core materials, it can effectively block heat transfer, significantly reduce building energy consumption, and meet green building standards.

Excellent fire safety: Provides different fire protection options from B1 level to A level (depending on the core material) to meet the fire protection requirements of various buildings.

High strength and lightweight: The board has high strength and light weight, which can effectively reduce the load on the main structure and lower the foundation cost.

Good sound insulation and noise reduction: The multi-layer composite structure can effectively absorb and block noise, creating a quiet indoor environment.

Beautiful and durable: The color coated surface layer has a long-lasting color, is weather resistant and stain resistant, has low maintenance costs, and maintains the long-term beauty of the building.

Advantages of composite sandwich panels

Quick installation and time-saving: Prefabricated panels in the factory, modular assembly on site, construction speed far exceeds traditional masonry methods.

Complete system and reliable performance: We can provide specialized connectors, sealants, and edge finishing systems that are compatible with the board, forming a complete enclosure solution to ensure waterproofing and airtightness.

Economic efficiency and low lifecycle cost: Although the initial investment may be high, its excellent energy-saving effect, extremely low maintenance requirements, and long service life make the overall lifecycle cost more advantageous.

Flexible customization and strong adaptability: The thickness, core material, surface layer, color, and board type (such as hidden nail and exposed nail corrugated boards) can be customized according to project requirements, matching different climate and aesthetic requirements.

Main application areas

Industrial buildings: Roofing and wall systems for various types of factories, production workshops, and warehouses.

Logistics warehousing: cold chain warehouses, logistics distribution centers (with extremely high insulation requirements).

Public and commercial facilities: sports venues, exhibition centers, supermarkets, office building partitions.

Cleanroom: Industries such as electronics, pharmaceuticals, and food that require cleanliness.

Others: prefabricated temporary buildings, sound barriers, energy-saving renovations of existing buildings, etc.

Composite sandwich panel is not only a material, but also a mature and reliable building enclosure system. It combines materials science and process technology to provide customers with excellent solutions that integrate structural safety, energy conservation and environmental protection, efficient construction, and aesthetic economy. It is the preferred material for building modern sustainable buildings. Canglong Group ensures that every sandwich panel can maximize its value in the project through a full chain service from design, production to technical guidance.
