40ft Standard Pre-Owned Steel Container
From $1,700 / unit
Sealed full-size unit at an honest price —
The 40ft Standard WWT container puts a full 304 sq ft of sealed, weatherproof steel on your St. Petersburg property at a price that keeps large-scale projects within reach. Verified wind and water tight, this unit keeps Florida’s storms, humidity, and pests on the outside where they belong.
A popular selection for classic car storage, boat winterizing shelters, contractor equipment yards, and multi-bay workshop setups across the Tampa Bay region. The 40-foot interior gives you room to park vehicles, organize deep shelving runs, or section off dedicated work zones without running out of space. Doors seal properly and the roof sheds water as designed.
Surface condition tells the story of a working container — rust patina, dent marks, and scuffs are all standard at this grade. The important thing is that the envelope holds. For property owners who need large-format secure storage without the ongoing expense of a commercial rental unit, the 40ft WWT eliminates monthly fees and puts that space under your direct control permanently.

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 Wind & Water Tight Classification
Wind & Water Tight (WWT) containers are retired ocean freight units that remain fully sealed against the elements. They no longer carry CSC certification for international shipping, but they keep rain, wind, and pests out reliably — exactly what most building and storage projects require.
Expect visible signs of service life: surface rust, dents, scratches, and general patina. The structural bones — corner posts, floor crossmembers, and roof bows — are intact and solid. Doors open and close properly and seals are functional.
WWT is the sweet spot for budget-conscious builders who plan to insulate, frame, and clad the interior anyway. Cosmetic imperfections disappear behind finished walls, making the lower price point a smart investment for workshops, storage buildings, and value-oriented living spaces.
Wind & Water Tight Grade Includes:
- Sealed against wind & rain
- Structural frame intact
- Functional door seals
- Solid floor condition
- Corner castings intact
- Secure locking hardware
Sealed against wind and rain but no longer certified for ocean freight. Visible signs of service life — surface rust, dents, patina. Solid choice for storage, workshops, and budget-conscious builds.
