20ft Standard Pre-Owned Steel Container
From $950 / unit
Rock-bottom pricing for experienced builders —
The 20ft Standard As-Is container is the most affordable way to get a steel structure onto your property. Sold in current condition without guarantees, this unit is built for seasoned DIYers and experienced fabricators who know how to assess and address structural issues themselves.
Well suited for non-critical storage, fencing projects, retaining walls, and creative salvage builds around St. Petersburg. Expect heavy cosmetic wear — significant rust, dents, and possible small holes. The Corten steel frame remains, giving you a solid starting point if you have welding skills and a vision.
At under $1,000, the 20ft As-Is puts a 150 sq ft steel shell within reach of nearly any budget. Factor in your repair costs honestly — if you have the skills and tools, this can be the foundation of an impressive build at a fraction of what higher-grade units cost.

Modification Advantages for Building Projects
The 20ft 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 150 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 20ft 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.
