A 20’ standard used shipping container is a cost-effective and durable solution for businesses and individuals seeking secure storage, transportation, or modification potential. These containers, measuring 20 feet in length, 8 feet in width, and 8 feet 6 inches in height, are constructed from Corten steel, offering excellent resistance to rust and harsh weather conditions. Designed for intermodal shipping, they feature cargo doors with lockable handles, durable wooden flooring, and weatherproof seals to protect goods from moisture and pests. While used containers may show minor dents, surface rust, or faded paint, they remain structurally sound and ideal for repurposing into storage units, job site offices, or modular buildings.

Features
- Venting: A standard shipping container typically comes equipped with two to four passive vents, usually located near the top corners of the sidewalls. These small, louvered vents help facilitate limited air circulation and reduce internal condensation by allowing moisture-laden air to escape.
- Lockbox: A used 20′ container does not include a built-in lockbox, but a lockbox kit is available for easy installation, providing added security.
- Floor: The floor of a 20′ used shipping container is typically made of marine-grade plywood, supported by steel cross-members for added strength and durability. This heavy-duty plywood, usually around 28mm (1.1 inches) thick, is designed to withstand heavy loads and resist moisture, making it ideal for storage and transport. While used containers may show signs of wear, such as scratches, stains, or minor surface imperfections, the flooring remains structurally sound and suitable for most applications
- Forklift Pockets: Most 20-foot standard shipping containers come equipped with forklift pockets to allow for easy handling with forklifts or heavy machinery. These pockets are typically located on the bottom side rails of the container and are designed to accommodate standard forklift tines.
- Pocket Width: Approximately 14 inches (35 cm)
- Pocket Height: Around 4.5 inches (11.5 cm)
- Pocket Spacing (Center-to-Center): Approximately 69 inches (175 cm)
- Position: Integrated into the side rails of the container floor
Acceptable Condition
A used shipping container should be structurally sound with no major damage that compromises its integrity. Acceptable conditions include surface rust, faded paint, minor dents, and scratches, as these do not affect the container’s functionality. The doors should open and close properly, with intact rubber seals to prevent water leaks. The floor should be solid and free of major rot or soft spots, though some surface wear is normal. The container should be wind and watertight (WWT), meaning no holes or significant damage that allows water or pests inside. While cosmetic imperfections are expected, the unit must remain secure, durable, and suitable for storage, transport, or modification.
Required Clearances for Delivery
To ensure a successful delivery of your shipping container, it is important to have adequate clearance and space prepared.
- 20 ft. container: 60 ft. of straight clearance is required.
The measurement should be taken from the point where the back of the container will sit.
Additionally, the truck delivering the container will require a total width of 12 feet. To safely drive under any obstacles, 14 feet of vertical clearance is necessary for the truck and container. At the actual delivery site, there should be a vertical clearance of 16-20 feet (depending on the truck and trailer) to ensure a safe tilt-off delivery.
