Open Side Container

An open-side container, also known as a side door container, has extra doors that open on the long side of the container. The open side makes it extremely convenient to load cargo that is bulky and can’t fit through the end doors. More workers can work simultaneously while loading or unloading cargo, as the side doors give full access to the container.

Open-side container sizes and dimensions

Open-side containers are available in three sizes. Here are the dimensions of each.

Open-top container

Open-top containers, as the name suggests, have an open top. The roof of the container is covered with tarpaulin sheets instead of a solid roof. This way, it can be covered or left open according to convenience. The container is made of steel with wooden flooring and the door heads can be swung open for easy loading and unloading.

Open-top containers are used when your cargo is too large to fit in a regular shipping container. For instance, machinery or heavy materials can’t be stowed sideways but arranged from the top through heavy-lifting cranes. These containers have larger capacities than the normal ones as the roof is open. It has lashing rings that keep the cargo stable and has the capacity to load 1000 kgs.

Double door container

Double-door containers are built to have doors that swing open outside on both ends. Both sets of doors are built with the same specifications. It is the most convenient option for loading and unloading a container, as you can load and unload goods quickly from either end of the container, as required. For instance, if you load a car, you can just drive it through a double-door container. You don’t need to reverse it while unloading.
