This is a single link of Marston or Marsden Matting.
Marsden Matting is standardized, perforated steel matting material originally developed by the United States at the Waterways Experiment Station shortly before World War II, primarily for the rapid construction of temporary runways and landing strips. The material is also commonly known as Marston mats (or Marston Plate) for a town in North Carolina adjacent to Camp Mackall airfield where the material was first manufacture] and used in November 1941. The material was also used in the Korean and Vietnam Wars where its common name, is pierced (or perforated) steel planking (PSP).
This is a single link of low poly planking. It is correctly built to scale and ready to be used for gaming and simulations. It has the exact number of holes found in the real material. All holes are done by way of Opacity, Bump, and Texture maps.
The aircraft sitting on the planking does not come with this model nor the grass texture and is shown strictly for demonstration purposes.
