How Long Do Shipping Containers Last?
Shipping containers were originally designed to streamline global trade. Over time, many large-scale developers have realized that these strong, cost-effective structures can be repurposed for a variety of uses. For enterprise buyers and commercial developers considering expanding with modular structures, understanding how long shipping containers last is important in determining whether they are a practical, long-term option.
How Long Does a Shipping Container Typically Last?
A shipping container used for its original purpose of transporting goods across seas typically lasts between 15 and 20 years. However, when repurposed as buildings, these containers can last significantly longer: up to 30 or 40 years with proper care and maintenance.
Shipping containers are primarily made from steel, known for its ability to resist corrosion and withstand exposure to the elements. The construction of these containers was designed to bear the wear and tear associated with international shipping. This includes harsh environmental conditions such as saltwater exposure, intense sun, and constant movement.
When repurposed for more static uses, shipping containers can last much longer, as they are no longer exposed to the same stresses and conditions. With the proper care, they can serve as long-lasting, practical, and cost-effective solutions for commercial developers creating modular spaces.
What Factors Influence a Shipping Container’s Lifespan?
Although steel is known for its durability, the lifespan of a shipping container is influenced by a variety of factors. Understanding these elements can help developers maximize the longevity and performance of repurposed containers.
Material Quality and Modifications
The quality of the material used in a shipping container plays a central role in its overall lifespan. Shipping containers are typically made from Corten steel, known for its rust-resistant properties, which enhances durability. If the container is made with thinner or lower-grade steel, it might deteriorate more quickly.
Modifications made to the container, such as adding windows, doors, or additional structural elements, also significantly impact its lifespan. Modifying the container can compromise its structural integrity, especially if not done correctly. For instance, cutting windows or doors into the sides of the container weakens its overall structure, and insufficient reinforcements could lead to issues like sagging or distortion over time.
These modifications are typically difficult or even impossible to correct once done, so it’s essential to get them right from the beginning. The more alterations made without careful planning, the more potential there is for problems that could shorten the container’s life.
Environmental Exposure and Placement
The environment in which a shipping container is placed has a significant impact on its lifespan. Steel generally performs better in drier conditions, where it is less exposed to moisture that can cause rust. For example, containers placed in an arid region will tend to last longer because the dry air causes less rusting and corrosion.
However, shipping containers can still fare well in wet or coastal environments, although these conditions require more upkeep and preparation. For example, a container located by the sea in a coastal town will need special treatment for saltwater corrosion, as the salt can cause the steel to rust faster.
Even within a less-than-ideal environment, the placement of the container is important. Placing a shipping container above ground, on a solid foundation, and away from direct exposure to elements like rain, flooding, wind, or extreme sun can dramatically increase its lifespan. For instance, positioning a container in a shaded area or on elevated ground can help protect it from the elements, allowing it to last much longer than if left exposed.
Use and Handling
The use and handling of the shipping container will also impact how long it lasts. A stationary container that is placed in a fixed location, such as a container home or office, will generally last longer than a container that is frequently moved. This is because frequent movement subjects the container to wear and tear from transport, which can cause structural damage, especially if it is loaded or unloaded improperly.
For example, a business that wants a mobile retail unit or food truck will subject its shipping container to regular movement. Constant vibrations and shifts from travel can weaken the container over time. On the other hand, if the container is installed permanently at a location, with no movement required, it is likely to endure longer.
How Can You Make a Shipping Container Last Longer?
Starting with a high-quality container is essential, but it’s equally important to know how to maintain a shipping container structure. To ensure a shipping container lasts as long as possible, there are a few key considerations.
Strengthening the Structure
When repurposing a shipping container, the structure’s strength is paramount. Reinforcing the container with additional steel framing or structural support can prevent warping or sagging over time. Insulation is another important factor, especially if the container will be used for residential or commercial purposes. High-quality materials such as foam insulation or spray-on coatings help maintain temperature control and prevent moisture buildup, which could lead to corrosion.
Upgrades for Longevity
Upgrades like protective coatings are crucial to extend the life of your container. A high-quality paint or rust-resistant coating can help protect the steel from the elements, particularly in wet or coastal areas where rust is a bigger concern. Ensuring the container is properly sealed and adding weatherproofing measures like roof covers or drainage systems will also protect against exposure to harsh weather.
Routine Maintenance
Regular inspections and timely repairs are essential for maintaining the integrity of the container. Checking for rust, leaks, and any structural damage ensures minor issues are dealt with before they worsen. Routine maintenance, such as cleaning and resealing, helps protect against environmental stressors, keeping the container in top condition for years to come.
