A 20-foot open side container is a type of standard container that has additional side doors for easy and quick access to the contents of the container. Unlike standard containers that have doors only at one end, open side containers have doors that open along the entire length of one side of the container, allowing for easier access for loading and unloading goods.

Open side containers are often used for transporting bulky and heavy goods, such as industrial machinery, construction materials, site equipment, spare parts, etc. They are also used in the event industry for outdoor events, concerts, festivals, etc., as they provide additional storage space for sound and lighting equipment.

The 20-foot open side containers have the same dimensions as a standard 20-foot container, but they have additional doors that increase the opening width to about 4.3 meters. They are made of sturdy, weather-resistant steel to protect the contents from moisture, dust, and damage during transport.

In summary, a 20-foot open side container is a variant of a standard container that is designed to facilitate the loading and unloading of bulky or cumbersome goods.
