Home > Composites > HDPE Sandwich Panel
HDPE sandwich panels are a composite material consisting of three layers. The core layer is made of high-density polyethylene (HDPE), which is sandwiched between two outer skins made of materials such as aluminum, galvanized steel or stainless steel. This structure offers high strength, hardness and resistance to environmental wear. It will not sag, dent or wrinkle in extreme weather conditions. It is the material of choice for manufacturing enclosed trailer bodies.

Panels for Freight Trailer Bodies
How to Install Panels?
Adhesive connection
- Adhesive connections use industrial-grade adhesive to hold sections of H-beams together. This method is easy and quick to operate.
Rivet connection
- Rivets provide a strong connection with good durability and stable performance when withstanding heavy loads or long periods of use.
Applications
- Construction industry.
- Industrial equipment.
- Transportation Equipment.
- Decorative materials.
- Enclosed freight trailers.
Application of HDPE Sandwich Panels in Freight Trailer Bodies
The lightweight and durable properties of HPET sandwich panels make them widely used in wall panels, roof panels and floors of freight trailers. The moisture-proof and impact-resistant properties of its panels ensure that cargo remains safe even in harsh transport conditions.
