Description
Product Introduction
Sandwich Panels are three-layer composite materials consisting of two outer metal sheets (or other materials) and an insulated core, offering lightweight, high strength, thermal insulation, and fire resistance. The closed-cell core structure prevents moisture condensation, while customizable outer layers (e.g., galvanized steel, coated aluminum) adapt to diverse environments. Widely used in industrial plants, cold chain logistics, and temporary structures, they represent an efficient solution for modern construction
Industry & Warehousing: Factory roofs, warehouse partitions, cleanrooms (rockwool core for dust control).
Cold Chain: Freezers, refrigerated trucks (PU core for insulation).
Commercial: Mall facades, stadium roofs (30+ color options).
Temporary Structures: Prefab houses, site offices (modular, 85% reuse rate).
Transport & Energy: Ship bulkheads, solar panel substrates (lightweight & corrosion-resistant).
▪︎ Lightweight & Strong: ≤24kg/m² weight, tensile strength 5600kg/cm², reduces structural load by 30%.
▪︎Energy Efficiency: Thermal conductivity as low as 0.022W/(m·K), cuts freezer energy use by 22%.
▪︎ Fire Safety: Rockwool core (A1 fireproof), PU core (B1 flame-retardant).
▪︎Fast Installation: Interlocking design, 40% faster construction.
▪︎ Eco-Durable: 35-year lifespan, recyclable, 28% lower carbon footprint.
