World War II Marston Mat - 17139

Marston Mat, properly pierced (or perforated) steel planking (PSP), 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 (also misspelled as Marsden matting). The nickname came from Marston, North Carolina adjacent to Camp Mackall airfield where the material was first used. A single piece weighs about 66 pounds and was 10 ft (3.0 m) long by 15 in (0.38 m) wide. The hole pattern for the sheet is three holes wide by 29 holes long resulting in 87 holes per mat. Priced per sheet.
