Duraplate Panels

Duraplate panels are a hard composite panel known for its resistance to corrosion, impact and abrasion. It consists of a core material (high-density polyethylene (HDPE)) sandwiched between two thin sheets of metal (usually aluminum or steel). This sandwich structure provides excellent structural strength, being stronger than foam core sandwich panels while being relatively lightweight compared to solid metal panels. Commonly used in the manufacture of trucks, trailers and containers.

In short, the advantages of Duraplate Panels are:

  • High strength: They are resistant to impacts, vibrations, and other forms of physical damage, resulting in extended service life.
  • Lightweight Design: Despite their superior strength and durability, Duraplate panels are relatively lightweight. This makes them ideal for applications such as trucks, containers and more as they can help reduce overall weight, thereby saving on fuel costs and increasing payload.
  • Corrosion Resistance: Duraplate skins are usually made of steel or aluminum, which gives them good corrosion resistance. This corrosion resistance allows it to maintain its appearance and performance in a variety of environmental conditions.
  • Non-absorbent: Its metal outer layer provides an effective barrier, preventing moisture from penetrating inside the panel. At the same time, the non-absorbent nature of the core material also helps prevent the penetration and absorption of moisture.

Applications in The Truck Industry

Duraplate panels are widely used in trucks, It provides strong structural support for the truck body, helping to improve the truck’s load-carrying capacity and fuel efficiency, and can withstand the challenges of long-distance transportation and heavy cargo. Inside the truck body, these panels protect the integrity of the cargo by effectively resisting impacts, vibrations and other forms of physical damage.
