About the 20ft flat rack conex box
A flat rack container is a heavy steel base with end walls and no sides or roof. Cargo is loaded from the top or the sides and lashed down, which makes it ideal for loads too wide, tall, or heavy for an enclosed box.
Many flat racks have collapsible end walls that fold down for transport or stacking when empty. Strong lashing points along the deck secure machinery, vehicles, and building materials.
Why 20ft?
The most popular size we sell. It balances space, cost, and easy delivery, and fits on most residential and commercial sites.
What fits

Questions about this container
What fits in a 20ft container?
About the contents of a one- to two-bedroom home, or roughly 10 standard pallets. Exact capacity depends on how the space is packed.
How much weight can a 20ft flat rack carry?
Flat racks are built for very heavy loads, roughly 60,000 lb on a typical 20ft unit, but road weight limits usually restrict what you can actually move. Check the rating on the unit’s data plate.
Can a flat rack be used for storage?
It can hold equipment, but with no walls or roof, goods are exposed to weather and theft. For storage, an open top or standard container is usually better.
Can I rent this container instead of buying it?
Yes. Choose Buy, Rent or Rent to own above and request a quote, and we’ll confirm what’s available for this unit in your area. See how conex rental and rent-to-own work.
Does the quote include delivery?
