 Refrigerated Railcar Products

The flooring system is constructed with sections of FRP, wrapped with stainless steel or aluminum plates and composite material, filled with foam.

Our door liner is made from a combination of urethane foam and composite materials.

These "A" and "B" railcar end sections are customized to manufacturers railcar design using light weight composites.

Introducing new products for refrigerated railcars from Martin Marietta Composites. These products include:

  • Floors
  • Wall Panels
  • Roofs
  • Door Liners
  • A & B End Units

Our components provide a longer service life and maximum protection for valuable refrigerated cargo. They feature urethane foam cores with engineered composite wraps yielding higher insulation values. Composite components are lighter weight and wood free, so they are easier to handle and will not warp, rot or mold.

Composite components are ideal for new railcar construction, since they are delivered ready–to–install or may be designed to retrofit existing cars.

Martin Marietta Composites can perform structural analysis and thermal testing to ensure our components meet your design criteria.
