Product overview
A 40ft used shipping container — also called a 40-foot conex box, conex container, or cargo container — is a pre-owned steel storage unit you own outright, delivering maximum capacity at the lowest upfront cost. At roughly double the floor space of a 20ft unit, it is the workhorse size for warehouses, construction yards, and large-scale inventory.
Are used 40ft containers still reliable? Yes. Each unit is thoroughly inspected to verify operational doors, intact flooring, and tight seals before delivery. Built from corrosion-resistant Corten steel to ISO standards with marine-grade plywood flooring and reinforced cargo doors, used containers protect gear just as well as new ones — with honest cosmetic character from prior shipping service.
Expect minor dents, scuffs, surface rust, and original shipping line markings. None of it affects performance. Ideal for manufacturing overflow, agriculture equipment, logistics staging, automotive storage, construction materials, and custom conversion projects. Units ship in stock for nationwide delivery, giving you secure steel storage on a timeline that matches project deadlines without waiting on custom lead times.
Buy your 40ft used shipping container online now while it is in stock, or rent this size from $139/month — both delivered in 3-7 days across the US. Pricing, specs, and FAQs are in the product tabs.

Delivery options
We offer two types of trucks for container delivery:
Tilt-Bed Truck (recommended if no unloading equipment is available):
The truck will back into position, tilt the bed, and slide the container off onto the ground.
Requirements: 125 ft of straight clearance, 12 ft width, and 16 ft vertical clearance.
Flatbed Truck (if you have a forklift or crane on-site):
A forklift (minimum 15,000 lb capacity) or crane is required to unload the container.
Requirements: 125 ft of straight clearance, 12 ft width, and 14 ft vertical clearance.
Site Preparation
Before scheduling delivery, please ensure:
- Clear, unobstructed access for the delivery truck
- No overhead obstacles such as trees, utility lines, or structures
- Dry, solid ground conditions (notify us if the ground is soft, wet, or muddy)
Containers are placed directly onto flat, level surfaces. No foundation is required for ground storage.
Delivery Timing
Delivery is typically completed within 1–3 business days after your container is ready for dispatch.
