Whether you’re a seasoned logistics veteran or an entrepreneur venturing into the shipping world, the relevance of open top containers is undeniable. In this article, we discuss this unique cargo transport solution in detail.
What is an Open Top Container?
Definition and Purpose of Open Top Container
An open top container is a shipping container with a removable roof, usually covered by a tarpaulin or detachable hard top. It is designed for cargo that must be loaded from above or is too tall to pass through standard container doors. Common uses include machinery, construction equipment, timber, pipes, and other oversized cargo.
Open top shipping containers are specialized cargo-hauling units designed without a fixed roof. Instead, they feature a removable tarpaulin or hard top cover and are typically constructed with durable steel frames.

The Benefits of Using an Open Top Container
Using open top container to manage your cargo comes with the following benefits:
Versatile Loading and Unloading
Unlike standard containers with fixed roofs and limited door sizes, goods can be loaded vertically from the top of open top containers using cranes or forklifts.
Ideal for Oversized Cargo
With their flexible roof design and removable top cover, open top containers provide ample vertical space, accommodating goods that surpass the height restrictions of standard containers.
Easy Access for Loading and Inspection
The absence of a fixed roof allows cargo to be loaded vertically from the top, simplifying the process with cranes or forklifts. Additionally, it grants effortless access to inspect and secure the cargo before sealing the container.
Efficient Loading of Bulk Materials
With the open roof design, bulk materials like grains, ores, and construction aggregates can easily fit into the container from the top. The absence of restrictive doors enables swift and cost-effective loading using conveyor systems or by directly tipping from trucks.
Suitable for Heavy Machinery and Equipment
Open top shipping containers enable hassle-free vertical loading and unloading, enabling cranes or forklifts to easily handle the substantial weight of machinery. The sturdy steel construction ensures the safe transport of heavy equipment over long distances.
Cost-Effective Transportation Solution
Open top hauling units eliminate the need for specialized and costly transportation. Vertical loading reduces labor and time costs, and the containers’ durability and reusability contribute to long-term cost savings.
Simplified Handling of Awkwardly Shaped Goods
The absence of a fixed roof and the open-top feature simplifies the handling of irregularly shaped cargo that might not fit through the standard doors of other container types. Cranes, forklifts, or other loading equipment make it effortless to load and secure items with unconventional dimensions.
Recyclable and Eco-Friendly Option
The construction of open top shipping containers incorporates durable steel, a material that’s recyclable at the end of its lifecycle, reducing the demand for new raw materials. Moreover, the containers can be repurposed for various applications, thereby minimizing waste and environmental impact.
Customizable Modifications for Specific Needs
From installing additional security features, ventilation systems, or reinforced flooring for heavy loads to creating specialized loading and unloading mechanisms, open tops accommodate diverse cargo types.
Airflow for Perishable Goods
Open top containers with hard tops offer airflow, as the open roof design allows natural air circulation and maintains optimal temperature and humidity levels within the container.
What are the Different Dimensions of Open Top Containers?
Common equipment options include:
- 20-foot open top container
- 40-foot open top container
- 40-foot high-cube open top container
- Carrier-specific hardtop equipment
Not every size will be available at every port or depot. Special-equipment availability depends on the shipping line, route, location, and cargo-ready date.
Overview of Standard Sizes: 20ft and 40ft Open Top Container
20ft and 40ft open container sizes are the most common ones with 8 feet width and 8.5 feet in height. The internal height may vary slightly depending on the container’s design, but it generally remains around 7.5 to 7.8 feet.
Internal and External Dimensions of Open Top Containers
The internal open top container dimensions are typically around 19 feet and 39 feet in length, 7.5 to 7.8 feet in width, and 7.5 to 7.8 feet in height.
Externally, the containers are approximately 20 feet and 40 feet in length, 8 feet in width, and 8.5 feet in height. These measurements may vary slightly depending on the specific manufacturer and design.
For businesses weighing equipment options, it’s worth noting that flat rack dimensions differ from open top specifications since flat racks have no side walls, a distinction covered in more detail in the comparison table below.

Open Top Container vs Dry Container vs Flat Rack
Choosing the wrong container can lead to rehandling, quotation changes, delays, or additional costs.
| Factor | Dry container | Open top container | Flat rack |
|---|---|---|---|
| Permanent roof | Yes | No | No |
| Full side walls | Yes | Yes | Usually no |
| End doors | Yes | Usually yes | Equipment-dependent |
| Top loading | Normally unavailable | Yes | Yes |
| Side loading | Limited | Limited | Usually possible |
| Over-height cargo | Generally unsuitable | Often suitable, subject to approval | Often suitable |
| Over-width cargo | Unsuitable | Usually unsuitable | Often suitable |
| Weather enclosure | Fully enclosed | Removable cover | Separate protection required |
| Typical use | Standard general cargo | Tall or top-loaded cargo | Wide, tall, heavy, or irregular cargo |
Choose a dry container when
- Cargo fits safely through the doors
- No overhead loading is needed
- Cargo remains within the container profile
- Standard enclosed equipment offers sufficient protection
Consider an open top container when
- Cargo must be lowered by crane
- Cargo is too tall for the door opening
- Cargo fits between the side walls
- Full container walls provide useful enclosure
- The shipment is over-height but not significantly over-width
Consider a flat rack when
- Cargo is wider than an open top
- Side loading is required
- The cargo has substantial overhang
- The item cannot pass through the roof opening
- The cargo shape makes full side walls impractical
Equipment selection should be based on technical cargo information rather than the cargo description alone.
