Application of New Composite Materials

TOPOLOGROUP has introduced new composite materials in the manufacture of swing doors that are lighter, more durable and more resistant to corrosion than traditional steel or aluminum alloys.

Refrigerated Truck Door Panels

Using PU (polyester) or XPS (extruded polystyrene) foam core FRP sandwich panels as door panel materials, this material is not only light in weight, but also has excellent impact resistance and thermal insulation, which is very suitable for transporting goods that require temperature control.

Dry Cargo Truck Door Panels

Using PET (polyester) foam, polypropylene honeycomb, plywood as the core material of FRP sandwich panels, and new FRP-CFRT (continuous fiber reinforced thermoplastic) as the skin material, these new FRP sandwich panel materials are light in weight and high in strength, avoiding deformation or damage of the door body due to excessive use.

Innovative Design

External locking bars and internal locking bars are two important door locking system installation methods for box truck doors.

The locking bars are installed on the outside of the box truck door to ensure that the door body can be securely locked when closed. It is usually used with a heavy-duty padlock or deadbolt. Generally, this door locking system is more durable, reliable and affordable.

These locking bars are installed inside the truck door panel, and the door handle is flush mounted. They work with the hinges and locking system of the truck door to further enhance the door body after the truck door is closed and prevent interference from inside and outside. This door locking system can enhance security and simplicity.
