40ft Standard Pre-Owned Steel Container
From $3,400 / unit
Roomy layout in near-new shape —
The 40ft Standard One-Trip container delivers over 300 sq ft of practically untouched steel shell — shipped once from the factory and retired from service. For builders who want maximum floor area in pristine condition, this is the unit to start with.
A top pick for high-end tiny homes, full-size ADUs, and premium workshop conversions across St. Petersburg and the Tampa Bay area. The One-Trip grade means factory-original paint, zero dents, and doors that swing open and shut with precision. Your construction crew can begin interior work on delivery day without spending a single hour on surface preparation or repairs.
The 304 sq ft floor plan accommodates a complete one-bedroom residential layout — kitchen, bathroom, living area, and sleeping zone — with room to spare. At 8'6" external height, the standard profile simplifies permitting on properties where height restrictions apply, while still providing adequate finished ceiling height for comfortable living.

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 One-Trip Classification
One-Trip containers are the closest you can get to new without buying factory-direct. These units were manufactured overseas, loaded with cargo for a single voyage, and retired upon arrival at a U.S. port. The result is a container with minimal wear — clean walls, intact paint, and virtually no dents or rust.
One-Trip units carry the full manufacturer warranty and arrive with crisp factory paint, straight panels, and smooth-operating doors. For projects where appearance matters from the start — showrooms, retail pop-ups, or premium living spaces — One-Trip eliminates the surface prep work entirely.
While the upfront cost is higher than other grades, the time and labor savings on exterior preparation often offset the price difference, especially for projects where you want to preserve or feature the original steel finish.
One-Trip Grade Includes:
- Factory-fresh condition
- Original paint intact
- No dents or rust
- Manufacturer warranty
- Valid CSC certification
- Smooth-operating doors
Nearly new — shipped once from overseas and retired from service. Minimal cosmetic wear with full manufacturer warranty. The cleanest option for living spaces and premium builds.
