EPS Sandwich Panels

EPS Sandwich Panels (also known as "sandwich panel" or "composite sandwich panel") is a lightweight composite material consisting of two metal face sheets (or panels made of other materials) and a foam core layer in between. Due to its lightweight nature, excellent thermal and acoustic insulation properties, and ease of construction, it is widely used in construction, cold chain logistics, temporary facilities, and other fields. Below is a detailed introduction to foam sandwich panels:

1. Main Structure

Face Sheet Materials:

Common materials include color steel sheets (galvanized steel, aluminum-zinc alloy steel), stainless steel, and aluminum sheets. PVC or fiber cement boards may also be used

The surface is often treated for corrosion and rust resistance (e.g., painted or laminated).

Core materials：

Expanded Polystyrene (EPS): Low cost, good insulation, but poor fire resistance (flammable).

2. Key Features

Lightweight & High Strength: Low density, easy to transport and install, suitable for rapid construction.

Thermal & Acoustic Insulation: Low thermal conductivity of foam core effectively reduces heat transfer and noise.

Water & Moisture Resistance: Metal face sheets provide a tight seal, preventing core absorption.

Cost-Effective: Lower overall cost compared to traditional brick-and-mortar structures, ideal for temporary buildings or large-span factories.

3. . Applications

Industrial & Civil Construction: Factory roofs, walls, warehouses, cold storage.

Temporary Facilities: Construction site offices, disaster relief housing, exhibition partitions.

Cold Chain Logistics: Refrigerated trucks, insulated containers.

Decorative Uses: Some interior partitions or ceilings (requires fireproof treatment).
