A Guide to Storage Containers

Shipping containers are no longer just for shipping; they've become one of the most practical storage solutions for businesses, homeowners, and construction teams. 

This guide covers everything you need to know about using shipping containers for storage. We will look at what you can store in them, the sizes available, and key features to look out for, as well as whether to buy or rent.

Additionally, we explain delivery and placement, plus how to keep your container in top condition.

What Is Typically Stored in a Shipping Container?

Shipping containers are used for short-term and long-term storage. They're strong, weatherproof, and secure—perfect for almost anything you need to keep safe and dry. Here's what people usually store in them: 

On-site equipment: Construction teams use it to store tools, ladders, generators, and heavy machinery. They help prevent theft and protect expensive gear from the weather. 

Temporary warehousing: Businesses use containers for overflow stock or while moving between locations. The ideal solution is when the door space runs out. Seasonal stock: Retailers store seasonal goods like Christmas displays, garden furniture, or sail items. Containers keep them dry and easy to access when needed. 

Home storage: During renovations or moves, containers store furniture, appliances, and building materials. They free up space and reduce clutter. 

Emergency storage: When things don't go as planned, such as sudden water damage or unexpected deliveries, containers provide quick storage space.

Types of Shipping Containers for Storage

The two most common sizes for storage are: 

20ft Containers 

• Roughly the size of a single garage 

• Fits the contents of a three-bedroom house 

• Easy to place on most sites

40ft Containers 

• Double the storage of a 20-foot container 

• Ideal for large equipment or book storage 

• Commonly used in Commercial and industrial settings 

Both sizes are available from TEU and come with delivery options. 

Key Features to Look for

When using a shipping container for storage, focus on these features:

Weatherproofing: All TEU containers are wind and water-tight, featuring rubber door seals and solid steel walls that keep rain and moisture out. 

Security: Look for containers with lockboxes that shield padlocks from tampering. Use heavy-duty padlocks and consider adding internal security features. 

Ventilation: Without proper airflow, condensation can build up; choose containers with vents to reduce moisture and protect stored items from mold. 

Buying vs. Renting a Shipping Container for Storage

Renting is best for short-term needs; it has a low upfront cost, making it great for temporary construction projects or seasonal retail. Buying is better for long-term use, as you can customize the container to suit your needs, and it offers a better return over time. 

If you need storage for under a year, renting may be more cost-effective. Buying usually works out cheaper and gives you more control. TEU offers both options and can help you decide what fits your needs and budget. 

How Are They Delivered and Where to Place Them?

Shipping containers are delivered by lorry. 

If space is tight, the crane can lift the container into place. You will need flat, firm ground and clear access for delivery vehicles. TEU handles the full delivery process. 

You may need planning permission in the UK. In most cases, you don't need planning permission, especially for temporary use, but in residential areas, it depends on the site and location. 

Maintenance Tips

Shipping containers are built to last, but regular upkeep helps extend their life and protect what's inside. A few simple checks every few months can make a big difference. Start by inspecting the container thoroughly; pay close attention to the roof and corners, as these areas take the most exposure from the elements. Look for dense standing water or obvious signs of rust. Open and close the doors to make sure the locking device works smoothly and check that the rubber seals around the doors are still intact. These seals are essential to keeping moisture and pests out. 

Inside the container, managing moisture is key. If you're storing anything sensitive, like fabric, paper, or electronics, place moisture traps or desiccant packs inside. These absorb the excess humidity and help prevent mold. Make sure the built-in air vents are clear and working. Raising stored items off the floor using pallets or shelving also improves air circulation and protects from potential leaks. 

Over time, the container's paint may fade or chip; touching up scratches quickly helps prevent rust from forming. For containers in high-use areas or visible locations, a full repaint using container-grade paint can improve appearance and extend the life of the steel. Some owners also apply anti-corrosion treatments for extra protection. 

It's a good idea to keep the area around the container clear; trim nearby vegetation and avoid letting mud or debris collect around the base. This helps water drain away and reduces the risk of rust along the bottom edges. After heavy rain or storms, give the container a quick inspection to spot any new damage, especially if branches or debris have fallen onto it. 

Pests can usually be an issue, but if you're storing food or textiles, check occasionally for signs of rodents or insects. Sealing small gaps and keeping the container clean will help prevent this. With basic care, a shipping container can stay secure and weatherproof for many years. TEU also offers advice on maintenance and repainting; just ask our team when you buy or rent.
