FERROPLAST Thermo Technology

The Leading Technology for Your Reefers and Dry Freight Vehicles.

FERROPLAST bodies offer you solid added financial value. Approximately 50% market share for box semitrailers in Europe proves their quality.

FERROPLAST combines the increased insulation of the new NX17 polyurethane hard foam with durable layered metal surfaces on both sides – Optionally available with HDR technology for extremely high buckling resistance. Using an adhesive joining process we utilise this material to construct boxes with completely vapour diffusion-tight surfaces. FERROPLAST bodies are energy efficient, hygienic, age-resistant and easy to repair.




Insulating core

The NX17 polyurethane hard foam technology : Large area foam injection results in absolute bonding with the surface layers. Foam moulded density approx. 55-95 kg/m³.

Tensile strength

320 N/mm² (StE 320).*

* Dependent on panel thickness and material combination

Corrosion resistance

Chemical-physical protection through zinc/steel cathodic effect.


Chemical / biological behavior

Resistant to standard commercial chemicals, odour-neutral, resistant to rotting and decay, resistant to fungi and microbes, physiologically harmless, certifcated suitability for food use.


The metal surface layers are absolutely vapour diffusion-tight: No loss of insulation properties or payload through the absorption of moisture.

Penetration resistance

With a ball diameter of 20 mm, forces up to 300 N do not cause any lasting deformation.*

* Dependent on panel thickness and material combination

Compression strength

10 % compression at a pressure load of 50 t/m².*

* Dependent on panel thickness and material combination

Thermal expansions

The expansion coeffcient of steel is approx. 50 % lower than aluminium and approx. 70 % lower than GRP. The folded seams completely compensate for the remaining thermal expansion, preventing any deformation.

Thermal capacity

Steel surface layers have a far lower heat storage capacity than carbon fbre: The vehicle's interior thus requires less time and energy to cool.
