Frequently Asked Questions


What is an HC container or high cube container? 

High cube (HC) containers are taller than the standard sized container. A typical container is 8.6 feet tall on the outside but a high cube container is 9.6 feet tall. 

Why are some cargo containers steel and some are aluminum? 

Typically, aluminum containers are made only to be used for domestic purposes and are not cargo-worthy. Why steel units work very well as storage containers, they are manufactured for sea cargo use. 


Are shipping containers for storage dry inside or will they leak? 

We make sure to check each of our units for any signs of holes (such as daylight shining through) and for any spots of concern. Considering containers are generally made of steel, they are subject to rust. While rust on the surface of the containers is always expected, we do our very best to make sure that it never leads to holes in the container. Most holes that develop are small and can be easily sealed. If there are large weakened areas or holes, we repair them with metal patches. Because these are common problems with used shipping containers, they normally undergo some kind of repair. If you are uncomfortable with purchasing a container that has been patched, ask up about a new container. 

Rust is unavoidable with storage containers but it usually harmless. However, it’s important that you routinely look over your container to make sure there is no damage – especially after it rains! 


What is container rain and how you can stop it? 

The term “container rain” refers to condensation that collects on the ceiling of a container. As the temperature changes outside of the container, it also changes on the inside sometimes leading to moisture developing. It can sometimes be a result of a door being left open as well so it’s important that you make sure your containers are sealed appropriately! 


How do I prevent container rain and control moisture and mold inside my container? 

There are many sprays that you can use to prevent moisture. We suggest Odoban. It’s safe, has a clean scent and fights mold. Spray it on the floors and surfaces and allow it to dry completely prior to loading up your unit. Make sure that all of the items you are storing are clean and dry. If you’re storing damp and dirty goods, you are inviting moisture and mold into your storage container.  We recommend that you set your storage items on a pallet. Pallets allow air to flow underneath which really helps reduce the potential for mold to develop.

We also recommend that you consider installing a turbine or running a humidifier. If you decide that you want to install a turbine, contact us to install one for you!  You can also install commercial desiccants made for containers. Shippers generally use these to control humidity and work well for storage units. You could also use desiccants made for boats and motor homes.


How can I keep my container dry? 

The term "wind and water tight" is used a lot in our industry. Did you know that all trailers and containers can develop condensation? Condensation develops due to high humidity levels and day-to-night temperature fluctuations. Here are some steps to protect your goods.

  • Reduce moisture with drying products. You may use products like Damp Rid; please review their website for appropriate recommendations.
  • For sensitive materials or longer term protection, the use of desiccants can be effective. A desiccant is a hygroscopic substance that induces or sustains a state of dryness (desiccation) in its local vicinity in a moderately well-sealed container. Please call AGM Container Controls for more information: 1-800-995-5590.
  • Inspect your unit regularly and after it rains. Make sure seals are in good order.
  • Keep the doors closed as much as possible.

Rental customers should call us immediately if they notice any type of damage to the unit (please review our lease for a full explanation of our damage policy). 


How much space is needed for delivery? 

A 20-foot storage container will need approximately 75 feet of straight clearance. For a 40-foot storage container, you will need around 100 feet of straight clearance. Width requirement is approximately 12 feet and a minimum of 20 feet overhead clearance is required at the drop off location. Any obstacles such as trees and overhead wires must be cleared prior to delivery. 


How do you deliver a portable storage container? 

We will deliver containers to you by a tilt-bed truck. The driver will back the trailer and lower the end of the container until it touches the ground. The bed of the truck will then pull directly out from underneath the container. If the container is to be delivered to a more confined area, a lift truck or crane can be used to set containers. 


Is there any site preparation necessary? Where can a container stand? 

The surface where the container is to be delivered should be fairly level, smooth, and firm. Due to the heaviness of the truck and trailer, a concrete pad, asphalt paving or other sturdy surface is preferred for the delivery location. Off-road deliveries are typically not done. If you need an off-road delivery, please discuss the road conditions with us in advance. Asphalt, gravel, grass, earth, and concrete surfaces are all acceptable locations for a container to rest. Containers are self-supporting at the four corners and so we recommend that on soft surfaces each corner is supported with a concrete footing, railroad ties, asphalt or a bed of gravel to spread the weight. This is also very important for container doors to operate smoothly. 



I was pessimistic ordering a can through a company out of state not being able to see what I bought until it was delivered. Yet honestly I am extremely happy I did. Addie was polite, professional, helpful and wonderful to work with. My expectations were exceeded above and beyond when the driver pulled into my driveway and I saw what I paid for. The can was in great shape , delivered when said to be and priced to bury competition. I will be referring them to everyone I know that's interested in a shipping container. Three companies couldn't even come within 800 bucks of matching their prices in half the condition of my container. Thank You Atlas for making my day.
