Shipping containers have revolutionized the global trade industry, providing a standardized, durable, and cost-efficient way to transport goods. While most people are familiar with standard intermodal containers, fewer are aware of the open top shipping container and its unique benefits. This type of container, as the name suggests, features an open roof, allowing for the loading and unloading of cargo that might be too tall or bulky for traditional containers. In this guide, we’ll explore everything you need to know about open top shipping containers—what they are, how they are used, their advantages, and how you can select the best one for your business.
What is an Open Top Shipping Container?
An open top shipping container is essentially a standard ISO shipping container, but with a crucial difference: it does not have a solid roof. Instead, the container is designed with a removable tarpaulin or a soft roof, allowing for the easy loading of oversized or irregularly shaped cargo that would otherwise be difficult to load through the standard door opening.
These containers are available in the same sizes as standard shipping containers (20ft, 40ft, etc.) and are primarily used for cargo that requires overhead loading or unloading. Open top containers are also used for transporting goods that cannot be easily loaded via conventional methods, such as cranes, forklifts, or other specialized equipment.
Key Features of Open Top Containers
Before diving into the use cases and advantages, let’s take a closer look at the features that define an open top container.
1. Removable or Retractable Roof
The most distinctive feature of open top shipping containers is their removable or retractable roof. Typically made of heavy-duty tarpaulin, this roof is easy to remove or roll back, allowing goods to be loaded from above, which is particularly useful when the cargo is too tall for traditional loading methods.
2. Versatility in Loading
Open top containers can accommodate a wide variety of cargo types, particularly those that cannot fit easily into a standard container due to size or shape constraints. The flexible roof system also means that oversized goods can be loaded by cranes, without worrying about the limitations of traditional container access points.
3. Durability
Like other intermodal containers, open top containers are designed to withstand harsh weather conditions and the rigors of international shipping. Constructed from steel, they offer significant durability and protection to cargo, even in extreme environments.
4. Standardized Sizes
Open top containers are available in the same sizes as standard shipping containers, with the most common sizes being 20ft and 40ft. These standardized dimensions make them compatible with the existing intermodal shipping infrastructure, ensuring they can be used in container ships, trucks, and trains with no special modifications.
5. Weather Resistance
Despite having an open top, the cargo inside an open top shipping container is still protected from the elements through the use of waterproof tarpaulin. Additionally, many open top containers are fitted with heavy-duty roofs made of materials like PVC, providing added weather protection. Dangerous goods container
Applications of Open Top Shipping Containers
Open top containers are often the go-to choice for businesses dealing with non-standard cargo. Below are some of the most common applications for these versatile containers:
1. Oversized Cargo
One of the primary reasons for using an open top container is the need to transport oversized goods. These include machinery, construction equipment, and large industrial components that cannot fit into a regular container. The ability to load goods from above using a crane makes it much easier to load and unload heavy or bulky items.
2. Construction Materials
Many businesses involved in the construction industry opt for open top containers to ship construction materials such as steel beams, large pipes, or precast concrete components. These items often need to be loaded from above, making open top containers an ideal choice for transportation.
3. Project Cargo
Open top containers are frequently used for project cargo, which refers to large, complex, or heavy cargo typically associated with infrastructure and energy projects. This includes things like turbines, generators, and other heavy industrial equipment that require specialized handling.
4. Fragile Goods
While not as commonly used for fragile goods as standard containers, open top containers can be useful for shipping delicate materials that might require extra care during transport. With the right precautions, open top containers can be used for goods like glass, electronics, and other sensitive items.
5. Refrigerated Cargo
Although less common, open top containers can be used in conjunction with refrigeration units (called “reefers”) to transport perishable goods that require a controlled temperature environment. This setup ensures that both the cargo is protected from the elements and its temperature remains consistent throughout the journey.
6. Agricultural Products
For some agricultural products, especially those that need to be shipped in bulk (such as grains, vegetables, or fruits), open top containers provide easy access for loading and unloading. Furthermore, the flexible roof allows the cargo to breathe, reducing the risk of spoilage from moisture accumulation.
Advantages of Open Top Shipping Containers
Open top shipping containers offer several key benefits compared to their standard counterparts. Here’s why you might consider opting for this type of container:
1. Flexible Loading and Unloading
Perhaps the greatest advantage of open top containers is their flexibility in loading and unloading. Goods can be lifted and loaded from the top, which is especially useful when forklifts or cranes are required for handling. This makes them ideal for transporting heavy, bulky, or oversized cargo.
2. Suitable for High or Irregularly Shaped Cargo
Because there is no roof, open top containers are especially well-suited for cargo that is too high or has an irregular shape. This could be anything from machinery to construction materials or oversized equipment. The flexible roof allows for large items to be placed inside the container without concern for fitting through the standard side door.
3. Improved Cargo Protection
The heavy-duty tarpaulin used to cover the open top provides weather protection for cargo, keeping it dry during transit. Additionally, since open top containers are made of high-strength steel, they provide protection from external forces, such as rough handling or harsh weather conditions.
4. Reduced Loading Time
The use of cranes or specialized equipment to load and unload cargo from the top typically reduces the overall loading and unloading time. Since it doesn’t require any complex maneuvering of the cargo, it can often be done more efficiently, especially for heavy loads.
5. Cost-Effective for Special Cargo
For businesses that need to ship cargo that doesn’t fit into standard containers, open top containers offer a cost-effective solution. Instead of paying for a custom container or special transport, open top containers provide an affordable way to ship oversized or irregular items.
6. Versatile Usage
Open top shipping containers are not limited to any one type of cargo. Whether you’re transporting construction materials, project cargo, or agricultural products, the open top container’s versatility makes it a valuable tool for shipping a variety of goods.
How to Choose the Right Open Top Shipping Container
When selecting an open top container, there are several factors to consider to ensure it meets your needs. Here’s what to keep in mind:
1. Size Requirements
Open top containers are available in different sizes, with the 20ft and 40ft containers being the most common. However, there are also high-cube containers, which offer additional height for cargo. It’s important to choose the right size based on the dimensions of the goods you plan to transport.
2. Weight Capacity
Each container has a specific weight limit. Make sure to check the maximum payload capacity of the open top container you plan to use to ensure it can accommodate the weight of your cargo. Overloading a container can cause damage or delays, so it’s essential to stay within the specified weight limits.
3. Roof Material
While most open top containers use tarpaulin for the roof, some containers may come with different roof options, such as solid PVC or even a retractable hard top. Depending on your cargo and the conditions it will be exposed to, you may want to choose a container with a more robust roof material for additional protection.
4. Condition of the Container
If you are purchasing or renting an open top container, it’s important to inspect the condition of the unit. Look for signs of rust, structural damage, or wear and tear on the roof. A well-maintained container ensures that your cargo remains safe during transport.
5. Shipping Route and Regulations
Make sure that your chosen open top container complies with the regulations of the shipping route you plan to use. Different countries and regions may have specific rules regarding container types, weight limits, and cargo safety. Be sure to check with your shipping provider or logistics partner to ensure everything is in order.
