What are Ocean Shipping Containers?

Ocean shipping containers are large standardized shipping containers designed and built for freight transport via ocean. They vary in size, style, and function.

Quick tips about Ocean Shipping Containers: 

- The sizes are listed in feet.

- Their internal or door opening dimensions are generally standard, but slightly change depending on the carrier. While small, these differences can have an impact on shipments.

- Most containers are made of steel with corrugated sides and their floors are made of treated wood so cargo can be blocked and braced with lumber and nails.

- When the weight of your cargo is too concentrated or heavier than normal loads, it can break the bottom of the container, so you must make sure you are distributing the weight of your cargo evenly. Alternatively, you can get appropriate accommodation for heavy or oversized loads.

What are the different types of Ocean Shipping Containers? 

There are many types of ocean shipping containers used to accommodate the different needs of your cargo.  Here are some examples: 

Hardtop Container- These containers are made specifically for heavier freight. They are manufactured with removable steel roofs, to ease the packing process with the use of cranes and other machinery. 

Dimensions- L x W x H


Flat Racks - These are designed for the transport of heavy, bulky, or oversized (OOG-Out of Gauge) cargo.They can be stacked on top of one another to allow for the transport of multiple lots of large cargo. Flat rack containers are made with a steel frame and no side walls. They have wooden floors and fixed/collapsible end walls, which can fold flush with the base.

Dimensions- L x W x H


Platform Container- These containers are built to carry extremely heavy and oversized loads. They’re made of a steel frame, wooden floors and no end walls. 

Open Top Container-  These standard containers are used to transport overweight cargo. Instead of a rigid roof, these containers have a flexible tarpaulin top which can be removed or just moved to ease loading. The end walls of these containers are also flexible and can be easily adjusted. They also feature roof bows to help stabilize the container during loading and transport. 

Dimensions- L x W x H


Reefer Container-  These are refrigerated containers, featuring thermal, insulated units with compressors to heat and cool their packaged contents.  Most of these containers have adjustable ventilation for better internal airflow. They’re used for temperature-sensitive, perishable goods.
