40-foot flat rack containers are a type of maritime container used for transporting bulky and heavy goods that cannot be transported in standard or open-top containers. They are similar to 20-foot flat rack containers, but have a higher load capacity due to their size.

The external dimensions of a 40-foot flat rack container are approximately 12.19 meters long and 2.44 meters wide, which provides more space for loading bulky and heavy goods. Just like the 20-foot flat rack containers, the 40-foot flat racks have no roof or side walls. They are equipped with steel beams at each end, which allows goods to be easily loaded and unloaded from the top or sides.

40-foot flat rack containers are often used for transporting bulky and heavy goods, such as machinery, heavy equipment, oversized parts, cars, boats, beams, etc. They can be equipped with lashing straps to keep the cargo in place during transport.

40-foot flat rack containers can be transported by land, sea, or air, depending on the client's needs. They are often used in the freight and logistics industry, as well as in the construction industry.

In summary, 40-foot flat rack containers are a practical solution for transporting bulky and heavy goods that cannot be transported in standard containers. They allow for great flexibility in loading and unloading cargo, as well as protection against the elements and damage during transport.
