40ft Standard Pre-Owned Steel Container
From $1,350 / unit
Over 300 sq ft of steel at the lowest price —
The 40ft Standard As-Is container is the most square footage you can get at the lowest cost in our entire lineup. Over 300 sq ft of Corten steel structure, delivered to your St. Petersburg property for builders who measure value in dollars per square foot rather than cosmetic finish.
Commonly used for construction site material storage, landscaping supply depots, boat and RV shelters, and large-scale salvage build projects across the Tampa Bay region. These containers carry the marks of extensive ocean service — heavy oxidation, significant denting, worn floors, and areas that likely require attention from a competent welder. The upside is a price that makes 300+ sq ft of steel structure accessible to nearly any project budget.
For experienced hands who treat container rehabilitation as part of the build process rather than an obstacle, the 40ft As-Is is where the most ambitious projects start. Evaluate the unit honestly, price out your repairs, and you may find that even with rehabilitation costs, you are still well ahead of any alternative building method for this much enclosed space.

Modification Advantages for Building Projects
The 40ft Standard ranks among the most versatile containers for conversion work. Here is what makes it a preferred starting point for builders and property owners:
- Roughly 304 sq ft of habitable floor area — room for a complete one-bedroom layout including kitchen, bathroom, and lounge
- 7'10" raw interior ceiling — standard height suitable for workshops, storage, and office conversions
- Weathering steel (Corten) shell — self-protecting steel that forms a rust-resistant patina, engineered to endure 25-50+ years along Florida's Gulf Coast
- Works with conventional framing — inner measurements support standard 2x4 stud walls paired with closed-cell foam, so any licensed contractor can handle the job
- Full-width rear doors — keep them for a statement entrance, swap them for floor-to-ceiling glazing, or seal and reframe for additional wall area
- 28mm marine plywood subfloor — delivers a flat, sturdy base ready to accept any final flooring finish
- Modular and stackable — arrange units side-by-side or on two levels to form multi-room or two-story configurations
Did You Know?
Converting a 40ft Standard typically runs 40-60% below the cost of conventional stick-frame construction for equivalent square footage. Across St. Petersburg, property owners are turning to container-based ADUs (Accessory Dwelling Units) to earn rental income or provide housing for family.
Florida has become increasingly ADU-friendly, with new legislation making it easier to add a container-based dwelling to your property.
Understanding the As-Is Classification
As-Is containers are sold in their current condition without warranties or guarantees. These units have seen extensive service and may show heavy rust, significant dents, floor wear, or small holes. They represent the lowest price point in our inventory.
As-Is containers are best suited for experienced builders who can assess structural condition and make repairs themselves. Common uses include non-critical storage, fencing material, retaining walls, and creative DIY projects where cosmetic condition is irrelevant.
For hands-on renovators with welding and fabrication skills, an As-Is unit offers the most container for the least money. Factor in repair costs when comparing to higher-grade units — sometimes the labor savings of a CW or WWT unit make them a better overall value.
As-Is Grade Includes:
- Steel frame structure
- Corner castings present
- Cargo doors included
- May have cosmetic damage
- Possible rust or dents
- Sold without guarantees
Sold in current condition without guarantees. May have significant cosmetic damage — heavy rust, dents, small holes. Best for experienced builders, fencing, or non-critical storage projects.
