What Is an Open Top Container?

An open top shipping container is a type of container that is built without a fixed roof. The open design simplifies the loading process and is beneficial for oversized and irregularly shaped cargo.

Instead of a roof, they feature a removable waterproof tarpaulin cover that provides suitable coverage. They’re widely used across construction, manufacturing, engineering, agricultural and mining sectors where industrial machinery and equipment are regularly handled.

20ft open top shipping containers offer a versatile option for transporting specialist cargo that cannot be loaded into a standard container, while still providing the durability of an ISO-compliant shipping unit.

Key Features of Open Top Shipping Containers

Open top containers are most commonly available in standard 20ft and 40ft lengths and are manufactured to ISO shipping container dimensions. They feature an open layout for convenient top-loading access, a removable tarpaulin roof for weather protection and roof bows for structural support. 

Their heavy-duty steel construction makes them ideal for handling oversized or over-height cargo, which is loaded in from the top. This sturdy design enables secure cargo transportation.

Below are two tables to show the working dimensions of both. Dimensions here allow for the structural metalwork that takes up a part of the overall size.

Advantages of Open Top Containers

Open top containers feature many advantages. Their open roof design allows goods to be loaded from above using an overhead crane. This makes them ideal for cargo that cannot be safely manoeuvred through standard container doors. Alongside easier loading, their heavy-duty steel construction is built to withstand demanding transport and storage environments. 

  • Accommodates oversized, over-height and awkwardly shaped cargo
  • Suitable for transporting steel beams, generators, machinery, pipes, and agricultural equipment
  • Faster loading and unloading help improve operational efficiency
  • Supports the safe and secure transportation of heavy cargo that cannot be loaded through standard container doors
