Sandwich Panels Suppliers

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.

Fire-resistant and Acoustic Sandwich Panels

Shanghe also supplies specialty fire-resistant and acoustic sandwich panels tailored for projects demanding high performance in either fire safety or noise control. These panels combine advanced core materials and multi-layer facings to meet strict regulatory standards in hospitals, schools, and specialized industrial facilities.

By choosing the right panel type for your project, you benefit from optimized insulation, structural strength, and compliance with U.S. building codes. Whether you need a polyurethane sandwich panels supplier, a rock wool supplier known for sound absorption, or fire-resistant sandwich panels provider, Shanghe offers customized solutions tailored to your exact specifications.

Technical Specifications of Sandwich Panels

Understanding the technical specs of our sandwich panels is key to choosing the right product for your project. Here’s a detailed look at the core materials, panel sizes, surface finishes, and performance ratings that define our offerings.

Core Materials and Densities

Our panels use a variety of core materials tailored for different insulation and structural needs:

• Polyurethane (PUR): Density ranges from 38 to 42 kg/m³, offering excellent thermal insulation with low thermal conductivity.
• Polyisocyanurate (PIR): Denser than PUR, typically 40 to 45 kg/m³, with enhanced fire resistance and thermal performance.
• Rock Wool: Density between 80 and 140 kg/m³, known for superior fire resistance and sound absorption.
• Expanded Polystyrene (EPS): Lightweight with densities from 12 to 16 kg/m³, cost-effective insulation.

These core options allow customization based on thermal insulation requirements, fire safety standards, and budget.

Panel Thickness and Dimensions

Our sandwich panels come in versatile thicknesses and dimensions to fit various applications:

• Thickness range: 30 mm up to 200 mm, depending on the insulation needed.
• Width: Standard widths from 1000 mm to 1200 mm for easy installation.
• Length: Customizable lengths up to 13 meters to reduce joints and speed up assembly.

This flexibility ensures you get panels that align well with your building’s structural demands and design constraints.

Surface Materials and Finishes

The surface facings of our panels are designed for durability and aesthetic appeal. Options include:

• Galvanized steel: Provides corrosion resistance and strength, ideal for harsh industrial environments.

• Color coated steel: Offers a wide range of colors with UV protection to maintain appearance over time.

All surface materials meet strict quality standards for weather resistance, wear, and impact durability.

Thermal Conductivity and Insulation Performance

Our sandwich panels deliver efficient thermal insulation with low thermal conductivity values:

• PUR panels typically have thermal conductivity around 0.022 to 0.025 W/m·K.
• PIR panels perform slightly better with values near 0.021 W/m·K.
• Rock Wool and EPS panels vary but maintain effective insulation for cold storage and climate control.

These values are crucial for reducing energy costs in commercial, industrial, and residential buildings.

Fire Ratings and Certifications

Safety is paramount, so our sandwich panels come with recognized fire ratings and certifications:

• European EN 13501-1 fire classification available on PIR and Rock Wool panels.
• UL94 ratings for flame retardant properties in relevant products.
• Certifications like ISO 9001, SGS, and CE ensure compliance with international quality and safety standards.

Choosing fire-resistant sandwich panels supports safer building practices in industrial and commercial projects.

Our detailed technical specs help you choose the right sandwich panels supplier who understands your needs for performance, safety, and durability. Whether you need insulated wall panels for cold storage or fire-resistant roofing panels, our options deliver trusted results.
