20ft Used Steel Shipping Container for Sale

These used shipping container units are a practical, durable answer for on-site storage, modular construction, and material handling. Retired from shipping lines, each unit provides weatherproof security for commercial and industrial work across the United States. Built from heavy-duty Corten steel, they withstand demanding environments.

Key Features

• Weather-resistant build: Corrosion-resistant Corten steel shields contents from rain, wind, and snow.
• Secure lockable doors: Standard lock boxes on both rear doors accept customer-supplied padlocks to keep stored items secure.
• Ventilated design: Passive vents promote airflow and reduce condensation during use.
• Functional flooring: Sustainable, weather-resistant plywood floor handles palletized cargo, machinery, and bulk storage.
• Standard dimensions: Built to external ISO specifications for easy transport and placement on level ground.

Shipping containers retire from active maritime service after roughly 15 to 20 years. While no longer meant for ocean transport or dynamic stacking, these used units are assessed for structural integrity and weatherproofing. Each is inspected for door function and exterior water resistance. Minor surface corrosion, cosmetic dents, or paint scratches are normal for used containers and do not affect their usefulness for static storage or conversion. They remain a popular pick for job-site material storage, equipment shelters, agricultural supply depots, and as cost-effective foundations for customized workspaces.
