The primary applications for sandwich panels fall into the following categories:
Industrial and Commercial Buildings
Share: Accounts for approximately 80% of total sandwich panel usage; this is the core application sector.
Specific Scenarios: Roofing and wall cladding for steel-structure industrial plants, logistics warehouses, shopping malls, and office buildings. Their lightweight, high-strength, and easy-to-install characteristics significantly shorten construction timelines.
Cold Chain Warehousing
Share: Accounts for approximately 15% of total sandwich panel usage; this is the second-largest application sector.
Specific Scenarios: Enclosure structures for low-temperature cold storage, refrigerated warehouses, and cold chain logistics hubs. The low thermal conductivity of polyurethane sandwich panels ensures stable low-temperature environments over the long term, drastically reducing energy consumption for refrigeration.
Other Significant Niche Applications
The remaining ~5% of applications are found in scenarios such as temporary modular buildings for construction sites, cleanrooms, and fire-resistant partition walls for high-risk industries (e.g., chemical and power sectors). These applications have specific, critical requirements for panel performance (such as Class A fire resistance or cleanroom-grade airtightness).
