How Much Impact Can a Container Withstand?

Freight units have revolutionised the way that cargo is transported around the world. They are made from corrugated steel and built to be extremely durable and long-lasting. This means that they can be used to transport large volumes of goods securely while withstanding harsh weather conditions associated with sea travel and long-haul transport.

Along with shipping, they also have various storage applications and are often used to store large or heavy loads safely on-site. Most people are aware that these units are extremely strong and resistant to damage, but do you know how much impact they can withstand?

Health and safety is a top priority when it comes to handling these units. It is essential that you understand how to use your unit safely and know how to get the most out of your unit. The good news is that shipping units are one of the most durable and well-built structures available and offer the ideal solution when it comes to your shipping and storage needs. With that in mind, let’s look at what makes them so strong.

Durable materials

Most units are constructed from congratulated steel, which is one of the strongest materials on earth. Steel is used in shipping units due to its durability and superior ability to withstand harsh weather conditions and resist atmospheric corrosion. Steel is extremely resistant to damage and should remain in excellent condition for many years.

Detailed construction

They are manufactured in line with a detailed and lengthy construction process. The different elements of the box are made separately before being assembled. Steps are taken throughout the construction process to improve the overall strength of the unit. For instance, square tubing is welded along the top and bottom of all panels to boost the strength of the structure. They are built with durability in mind and can have a high load and weight capacity. To give you an idea, most 20ft units have a load capacity of up to 32 cubic meters and can safely carry a weight of up to 44,000 lbs. 

Rigorous Inspections

These units undergo rigorous inspections before they leave the depot. In most cases, these tests involve the following: racking test, stacking test, sidewall strength test, door strength test, floor test, front end wall strength test, roof test and maximum gross weight testing. If any issues are found, then repairs are carried out before the unit is transported to its intended destination. You can also purchase an ISO container to ensure that your unit offers the highest levels of durability and quality. An ISO unit is any type of unit which is designed, manufactured, tested and certified to the standards set by the International Standards Organisation, in terms of size, strength and durability.


Units can last for more than 25 years with the correct care and maintenance. Most new units also come with a generous warranty of 10 years or more. This will give you peace of mind that your unit will give you many years of hassle-free service.
