The shipping containers are the backbone of the shipping industry, global trade, and supply chain. The shipping containers are large rectangles, which keeps your overall layout square and straight on the outside. The cargo containers are made in high-quality steel and are inherently durable.

Not given due consideration, they carry billions of cargo from near to far-off distances. Therefore, structural integrity maintenance is necessary to keep them in the right shape for years.

A few factors may affect the structural integrity of freight containers. Whether too many trips at sea (before modifications), too many alterations, or improperly stacking units – you should consider these factors when modifying shipping boxes to ensure your structure is safe.

Now, let’s see the three factors that affect the structural integrity of freight containers:

Frequent Sea trips

The structural integrity of a modified shipping container depends mainly on the number of times it’s been at sea. This is significant because, in the whole shipping container’s lifespan, they travel at sea frequently. Thus, they will experience more wear and tear than their land-locked equivalents. Sea travel substantially impacts the box’s integrity if you buy or are buying a used shipping container.

For starters, salt is quite corrosive. Over time, ocean travel exposes boxes to corrosive saltwater, severely influencing construction. Rust can form, and while the steel used for the freight container is relatively robust, it can cause significant structural damage if left unchecked.

Although rust may not be a problem for temporary storage (if there are no signs of leakage), the deterioration may render it structurally unsound and unsafe if you wish to modify the cargo box.

Furthermore, the repeated loading and unloading of the box is significantly more harmful than the dents and dings of regular use for a land-locked freight box, which increases the danger.

Too many modifications

Although adjustments to make shipping container homes from the regular shipping boxes, too many changes will compromise structural integrity.

Two techniques to cut into the container might damage the unit.

Corner castings: Each shipping container’s weight is handled by the corner castings – the box’s four corners. You will forfeit structural integrity if you chop off a corner casting to obtain a modified design. That is why it is critical for engineers and architects to understand how these freight units function structurally. It’s better to build around the storage box and its parts rather than forcing it to be something it’s not – that way, you get the most out of the unit while optimizing its strength.

Freight Container walls: While cutting to install shipping container doors, windows, and wall-mounted air conditioning units is routine, some cuts may be excessively large. These end up compromising the shipping container wall strength. For example, cutting off a whole wall of a maritime container will cause the roof to sink and the bottom to become springy. Even though the corner castings carry most of the load, the walls carry some weight. They work to preserve the form of the box, making them critical to structural stability. If you decide to make dramatic changes to your cargo shipping unit, think about what is needed to effectively strengthen the unit – without relying on the container’s integrity.

Improper freight container stacking

Stacking shipping containers on land or stacking the modified ones to facilitate more prominent buildings incorrectly might pose significant safety risks. Set-up teams should utilize the required equipment – a crane or an industrial-sized forklift. These are the proper tools to move the components into position while stacking a cargo shipping box. The crews should attach the stacked modules by the corners to form a single structure. The most structural support is provided by stacking the units at the corners rather than on a diagonal. Diagonally stacked boxes are frequently dangerous unless extra support is there. Twist locks, a type of container locks, is used as the devices to connect the corners of boxes together once they have been stacked, resulting in structurally sound multi-unit structures.

Not choosing the suitable freight container suppliers 

When selecting the correct container supplier to buy shipping containers online, the best advice is to go with a well-known company that serves the market. As not choosing the right one will affect your business adversely.

Always work with a well-established organization with a diverse portfolio, not just in one field but also internationally. This enables them to respond without delay, providing security and speed and reducing cargo hand-offs across networks. Container trading companies now encounter circumstances that necessitate last-minute or unanticipated shipments because of product line modifications, natural calamities, or surges in demand. In such cases, reputable companies with skilled sales staff and the capacity to design and implement solutions simultaneously would be beneficial. Also, make sure the container company you go for facilitates transparent processes. This way, you get notified at every step of the way.

Thus, you saw how you can always maintain the structural integrity of freight containers and keep them in prime condition and well-functioning for years.
