What Are sandwich panels suppliers
sandwich panels suppliers are advanced construction materials made up of two thin, strong outer metal facings bonded to a lightweight insulating core. This layered structure combines thermal insulation, structural integrity, and lightweight properties, making sandwich panels an ideal choice for modern construction needs. Typically, these panels use metal facings like galvanized steel or aluminum paired with various core materials such as polyurethane (PUR), polyisocyanurate (PIR), rock wool, or expanded polystyrene (EPS).

Types of Sandwich Panels Offered by Shanghe Your Trusted Sandwich Panels Supplier
At Shanghe, we offer a wide range of sandwich panels designed to meet diverse construction needs across the United States. Each panel type is engineered for specific performance benefits including thermal insulation, structural strength, fire resistance, and sound absorption.
Polyurethane PUR Sandwich Panels
Our Polyurethane (PUR) sandwich panels are known for their excellent thermal insulation and lightweight properties. The PUR core provides a low thermal conductivity value (typically around 0.022 W/m·K), making these panels ideal for energy-efficient buildings. They offer high structural integrity combining galvanized steel or aluminum facings, suitable for commercial and industrial applications.
Polyisocyanurate PIR Sandwich Panels
PIR sandwich panels feature a polyisocyanurate core, offering even better fire resistance and thermal performance compared to standard PUR panels. With improved insulation efficiency and a thermal conductivity value as low as 0.019 W/m·K, PIR panels are perfect for projects requiring enhanced energy savings and fire safety compliance. These panels are widely used in cold storage and clean rooms.
Rock Wool Sandwich Panels
Rock wool sandwich panels are favored for their outstanding fire resistance and sound absorption qualities. The core is made from mineral wool, which resists high temperatures and provides superior acoustic dampening. Rock wool panels are highly suited for environments where fire safety is critical, such as factories and public buildings.
EPS Expanded Polystyrene Sandwich Panels
Our EPS (Expanded Polystyrene) sandwich panels offer cost-effective thermal insulation solutions with decent fire-retardant properties. EPS cores deliver good performance for lightweight wall and roofing panels used in residential construction and modular buildings. These panels balance affordability with effective energy savings.
