Advantages:
We use FRP skin XPS foam board as the main structure. It improves heat insulation and impact resistance. Our semi-trailer body is the best high performance material. It is impact resistant, not easy to break and scratch.
- CUSTOMIZED THICKNESS: FRP foam boards can be customized with different thicknesses to meet better cold storage needs.
- Multi-temperature zones: SEMI trailers can be converted into multi-temperature zones for transporting different refrigerated goods.
- Customizable Insulating Foam Panels: PU, XPS and other high strength insulating foams are available.
- LONG LIFE: Ordinary trailers are expensive to manufacture, and if they have a short life expectancy, then that adds to the cost. Our structures last up to 10 years
- Abundant kits: we provide abundant kit choices and solutions for cold storage systems.
- Height can be customized: we provide body customization, which can be customized in different sizes according to requirements.
- Exquisite appearance: the trailer body surface is made of FRP panel with flat surface.
- Fast loading and unloading: different sizes of side doors can be customized to make loading and unloading faster and more efficient.
- Lightweight: with FRP skin and XPS foam, the total weight is much lighter than aluminum body, which can improve transportation efficiency and reduce cost.
- Excellent thermal insulation: our trailer body can realize excellent thermal insulation performance in the range of -20℃ to 50℃.
