How Weather Conditions Can Impact Your Shipping Container

Despite being built and renowned for their durability, given their original purpose of enduring long voyages across oceans, even the toughest shipping containers can be affected by the often unpredictable weather of the UK. Here in North West England, we know that when facing rain, dampness, frost, heat, and wide temperature swings, containers can begin to wear down, affecting their ability to safely store your goods.

Here, we’re going to look at the type of weather damage that can affect shipping containers, and what you can do to prevent it, extending their lifespan and keeping them reliable. 

Common Weather-related Issues For Shipping Containers

Despite being designed for resilience, exposure to the elements can affect containers. Here are some of the weather conditions you need to keep an eye on:

• Rain and Damp: Although built for water resistance, if your seals or doors deteriorate over time, moisture can begin to seep in. Water ingress can cause damp patches, mould growth, and rust, as well as affect the contents.

• Condensation: When warm, moist air meets the cold metal walls, it can lead to condensation. This container sweat happens during temperature shifts or when warm goods are kept in cold containers, which can damage packaging, paper products, fabrics, and electronics.

• Frost and Ice: The moisture around door seals can freeze in the winter, especially overnight. This can make them much harder to open and can strain the seals and hinges, which may cause leaks.

• Heat and UV Exposure: High temperatures and direct sunlight can cause paint fading as well as expansion and contraction of steel panels, and timber floor warping. Weakening coatings and materials can leave them more susceptible to corrosion.

• Winds: Despite their weight, unsecured containers can shift or tip over, especially in exposed areas like fields or coastal areas.

  
  

How Weather Affects Container Life And Performance

The elements above can have all manner of effects on the structure and functionality of your containers. For instance, they can begin to rust if they are scratched, dented, or their finish is compromised. Once it takes hold in vulnerable areas like corners or door hinges, it can spread and weaken the metal considerably. The goods stored inside can be highly affected, too, with items like paper, textiles, and electronics being susceptible to humidity, while food and organic materials can spoil or grow mould due to temperature fluctuations and condensation.

This exposure also means that containers will require more frequent maintenance, like repainting, resealing, or hinge lubrication. While these are minor tasks, they are a cost to consider, and neglecting them can lead to more serious damage.

Preventative Measures To Protect Your Container

Thankfully, there are steps you can take to reduce weather-related damage and extend the lifespan of your containers: 

• For rain and damp: Inspect your door seals and rubber gaskets for cracks or wear; check roof and corner welds for rust spots or damage; and repaint or touch up the exterior coatings when damage or corrosion appears.

• For condensation: Fit air vents to improve airflow and regulate the temperature; use desiccants to absorb humidity; and consider lining or insulating the container for long-term storage or sensitive items.

• For frost and ice: Lubricate the door hinges and locking rods to prevent freezing; use anti-freeze sprays during the cold months, and remove standing water nearby to prevent freezing.

• For heat and UV exposure: Repaint the container routinely with UV-resistant coating; position containers in shaded areas; and use roof coverings to reduce heat absorption.

• For wind: Place containers on level, stable foundations, and anchor them with twist locks, bolts, or concrete pads.

Site Preparation and Location Tips

Your choice of location and setup can make a big difference in protecting your containers from the weather. Place your containers on raised, level ground, and consider using blocks or pads to raise them off the ground level.

Leave space around the container to encourage better airflow, reducing condensation and preventing corrosion. You should also avoid placing them under overhanging trees, as falling branches, leaves, and other debris can damage the roof or block gutters over time.

When To Call In Professional Help

There are some issues that are best handled by the pros, especially if your container’s structural integrity is at risk. If you see visible signs of rust or corrosion, or your doors are becoming difficult to open or close, specialists can make the necessary repairs. If you think you might need any weatherproofing modifications, such as installing insulation, extra vents, or a full interior lining, then reach out to get the help that you need.

UK weather can be harsh on even the toughest shipping containers. It’s important to know the risks and to invest in the protection you need, alongside ensuring good site setup and proactive maintenance.
