How Long Can Shipping Containers Last?

A container’s longevity is impacted by a variety of factors.

As providers of shipping containers for sale in Perth, at True Blue Containers we know you want freight equipment that lasts the distance. Across the sea, and across the years.

Container usage

A container utilised only on land will last longer than a sea container shipping cargo across waters. 

A sea container can prove reliable for up to 15 years, possibly a few years less. Over time, cargo transport puts pressure on the structure, due in part to climate conditions.

Bodies of salt water elevate corrosion risk, and moving from ship to port to land transport can stress container integrity as the years pass.

In contrast, a container used for storage or road and rail transport only has the potential to perform well for decades. For a land-based container, up to 30 years is a reasonable expectation.

A container retired from marine transport can be sold and used as storage or for converted projects that repurpose the container. Depending on condition, conversion quality, usage, and maintenance, these container projects have the potential to last decades.

Quality control

While a new, better quality container can be costlier, a trusted manufacturer’s attention to detail translates to the likelihood of a longer shipping life.

Functional new containers have a CSC plate attached, showing they meet requirements for sea shipping. This safety approval is recognised for half a decade. After this period, inspections are required every 30 months to maintain the container’s sea-worthy CSC rating.

A comprehensive inspection is recommended for used containers, especially if investing in a shipping container for sea and rail transport.

The container should be able to pass a full Institute of International Container Lessors (IICL) inspection, complying with stipulations of the Convention of Safe Containers, confirming the container is safe for international travel.

True Blue Containers uses a comprehensive Convention for Safe Containers inspection checklist to make sure your container meets shipping standards.

For cargo or destinations with specialised needs, our experts can help with modifications that address regulatory requirements or enable necessary certifications.

Second-hand containers

For used container conversion projects or on-site storage, your container won’t need to face the rigours of sea travel and this should be taken into account at point of purchase.

Containers are generally referred to as in peak or new condition, meaning in their first year, or allocated an A,B, C or D grade, with D referring to damaged and non-secure containers.

Be aware grades, labels, and categories can differ between sellers, as Australia has no regulated standards. A reputable supplier will offer an in-depth survey of the container’s current condition.

We give second-hand containers a thorough inspection and grade accordingly, noting aspects like structural damage and integrity, helping you identify the best used container for your needs.

General care

Inspect your container at least once annually for signs of wear and tear. Delayed maintenance can worsen an issue and risk impacting the next CSC evaluation.

Common signs repairs are required include:

• Obvious corrosion

Treat rust before it deepens and becomes a structural issue. If your container has a roof, make the effort of a visual inspection.

• No longer watertight

To avoid puddles and mould, stand inside a dark container and check for light that indicates leaks. Door seals may also need replacing.

• Unreliable functions

Check and if necessary, overhaul reluctant locks and hinges. Perhaps consider updating your smart security system. 

Further tips on potential weak points are listed in things to consider when buying a shipping container.

Appearance

Paint work falls under maintenance. Repainting a container reinforces protection against the elements and improves the aesthetics of a container.

Always begin with a thorough clean of the outer surface. Any minor repairs and rust removal should take place now before moving onto painting.

 Do you have plans to prime? Choose a premium paint finish with a focus on weather-proofing. Talk to our team if unsure about the process.

Minimise moisture

With mould and rust greatly capable of reducing a container’s structural integrity and therefore service life, it’s important to address possible dampness.

• Letting dead leaves and branches accumulate on a container risks creating an environment that locks in moisture, encouraging rust. Schedule regular cleaning of the roof.
• Small dents are common. Beware of deeper damage leading to a misshapen structure, and tears that render a container no longer water-tight. Don’t delay repairs too long.
• Poor interior ventilation risks humidity becoming an issue inside the container. Talk to us about maintaining acceptable interior humidity levels by addressing your vent design.
• Avoid allowing water to pool. Elevating your container helps protect flooring, while an additional angled roof design is common for long-term storage and conversion projects.

Container location

Before buying or hiring a container, make sure your plans align with local shire requirements. This applies to containers for shipping, storage, and planned conversions, whether in domestic or commercial locations.

You need compact surfacing if you want to keep the door functioning on your container. If uncertain a surface will hold a container level, our team can advise on placement. 

On unprepared soft surfaces, the container is at risk of uneven sinkage that could prove harmful to the structure. Air circulation is also important, so plan any elevation carefully.

If possible, shield your container from direct sunlight during hot summer months. During the rainy seasons, ensure your set-up allows rainfall to drain away, avoiding pooling.

Humid climes can also reduce a container’s integrity. To address interior condensation, leave the container open or explore insulation, a dehumidifier, and better venting.

Container replacement

Once past the decade mark, deciding when a shipping container is best retired from the sea is the question. At some point, fighting to keep a container cargo-worthy is no longer cost-effective.

Time to weigh up short-term and long-term benefits. Our team is ready to help if you decide now is the time to purchase or hire another container. We specialise in sea containers for sale in Perth. To discuss container acquisition, contact us today.
