The standard shipping container is a fully enclosed steel container, a plywood floor, and double-action bolt doors.  Most new shipping containers are waterproof and air sealed. Dry storage steel shipping containers are the most common type with millions in circulation around the world.

Covered or Uncovered

Shipping containers come with or without roofs. A shipping container with no roof, called an open container, is mainly for shipping objects that are too tall to fit the standard height of a shipping container.

Uncovered shipping containers have the advantage of being cheaper and, for some purposes, tying down a tarp will be enough to keep the cargo dry and safe during transport.

Tunnel Type

Tunnel storage containers have doors on both ends of the container. This kind of container is good for easier and quicker loading of cargo. They are also good for access to storage from both ends of the container.

Carrying Capacity

The carrying capacity is the specification that gives you the volume of cargo you can store and ship in the container. Here are the estimated carrying capacities for most shipping containers of these lengths:

  • 10 ft. container (560 cubic feet)
  • 20 ft. container (1,160 cubic feet)
  • 30 ft. container (1,760 cubic feet)
  • 40 ft. container (2,360 cubic feet)

Custom Metal Storage Container Features

Standard shipping containers come with double-hinged doors at one end and are bare on the inside. Depending on what you are storing or shipping, a customized shipping container could be what you need. Here are a few of the special features that come with some containers or you can modify them to fit your needs after you buy.


As mentioned, the double-hinged door is the most common type of shipping container entry. This type of door is recommended for containers that need to be opened and closed on a regular basis.

Used Cargo-containers For Rent

There are shipping containers that come standard with rolling shutter type entry. Other containers have a single heavy thick door for stronger security. Shipping container doors are always strong and secure but some containers are designed to be extra secure to store more valuable content.

Seal and Paint

Shipping containers often come painted with weather-resistant sealant and paint. In some cases, you can order your container painted a certain color or even have your company logo printed on the sides, roof, or door(s). Having your container sealed and painted every couple of years will greatly increase its life expectancy.

Security Features

Shipping containers are usually secured by at least one bolt and padlock. Some designs have two or even three locks for added security. Some containers have advanced security features such as metal sleeves that protect the lock from the weather and prevent thieves from using a saw on the lock. A good shipping container lock is always a good idea to keep the contents safe from theft.


Windows are a good option if you are storing things that would benefit from letting in the fresh air and natural light. Having a window also allows light in the container so you can easily see when putting things in and taking things out of storage. Windows can help reduce moisture buildup inside your metal storage container that can damage your cargo or storage.

Heating and Cooling

Again depending on what will be shipped or stored in your container, some temperature control may be needed. This is particularly true in extreme temperature environments. Containers can be outfitted with AC or Heaters to regulate the interior temperature of the unit.


Install shelving in the storage containers for more efficient storage and more stable shipping of delicate merchandise. Heavy cargo can be forklifted to higher-level shelves to keep them from accidentally falling in transport or simply for more efficient use of the full volume of the container.

  • hazardous materials such as paint and paint thinners

Buying vs Renting Metal Containers

Leasing a storage container may be the right option for short term projects or if you only have a few shipments to make. If you are planning on years or even decades of regular shipping container needs then you most certainly should consider owning your shipping containers. You could save your business thousands in leasing fees.

Warranties on Shipping Containers

Do shipping containers come with warranties? Yes, most new shipping containers come with warranties. The terms of these warranties will vary depending on the manufacturer. The life expectancy of steel storage containers is anywhere from 10 to 30 years or more.

Permits for Shipping Containers

A common question we get is, do we need a permit to put shipping containers on our property? In many cases, a permit is not needed especially if the shipping container will only be on the property temporarily.

The truth is the laws are different everywhere so you will have to check with your local zoning and building planning committees to be sure you’re not breaking any laws. We recommend calling and asking about your local regulations before having shipping containers delivered to your business. Learn more about permits below.
