PolyBilt is a specially formulated co-poly and is a unique, cost-effective alternative to fiber composite or aluminium constructions. It excels by its body strength, resulting in stronger physical properties in either high or low-temperature applications. Sledgehammer and bullet-tested, it does not dent, absorbs impact energy and does not transfer collision forces to other components for the vehicle body.

Fire departments all over the world favor PolyBilt due to its flexibility, allowing integral services routing as well as integral water and foam tanks. PolyBilt bodies come with a limited lifetime warranty and can be transferred to other chassis.

Polyprene is a specially formulated co-poly. The material is well suited for fire appliance bodies and similar components because Polyprene is strong enough to resist cracking and fatigue resulting from constant movement. Polyprene can be painted and repaired easily when damaged. Polyprene will not rust, corrode, crack, chip or peel. Polyprene welds are impervious to microbial attack.

Impact Resistant

The Frankenlust Fire Department of Bay City, MI was glad they had a PolyBilt body when the vehicle rolled over on a slushy road. The peripherals were damaged, but the body (and the fire crew) were virtually unscathed.


UK fire services also like the impact resistance of PolyBilt:

"In a recent accident involving two fire tenders, there was far less damage than we would have seen with aluminium bodies. And the vehicles were back on the run in days rather than weeks."

Heat Resistant

  • Surface deformation begins at 275°C
  • PolyBilt bodies are welded at 375°C
  • A blowtorch at 660°C two feet from a body for thirty minutes did no damage
  • Vehicle paint will ignite and tires will melt before a PolyBilt body is affected

Chemical Resistant

PolyBilt has been tested for resistance to a wide range of chemicals, making it perfectly suited for applications where corrosion or acid attack are problems. See for yourself on this chart
