Dry container

A dry container is the standard general-purpose steel box that carries the bulk of containerized cargo: boxed, palletized, or bagged goods that need no temperature control. Built to ISO 668 and ISO 1496-1, the common sizes are the 20-foot (1 TEU), the 40-foot (2 TEU), and the 40-foot high cube at 9 feet 6 inches tall. All Series 1 boxes share a 2.438 m (8 ft) external width. Type code 22G1 marks a 20-foot general-purpose unit under ISO 6346, 42G1 the 40-foot. A 20-foot dry box holds about 33.2 cubic meters; a 40-foot high cube about 76.4. It loads through full-width rear doors and is wind-and-water-tight.
