The soft top has a tarpaulin roof, which is a milder material. This is a standard option in the shipping industry. Use lashing rings or large eyelets to hold it in place. Since then, roof bows have been used to support the tarp’s structural support.

All open tops feature a soft top that covers the container roof when the cargo is within specification, i.e., not larger than usual nor beyond the roof.

If your cargo is larger than the large custom tarpaulin you bought, you can even replace the covering with canvas or plastic sheeting to suit your load.

Ⅶ. Precautions when using an open top shipping container


In most cases, the cargo inside fits perfectly into the container size, so the tarp stays level. In this case, the containers can be stacked below other units without any structural problems.


If the cargo is large and bulky and cannot fit into the container, a portion of it will stick above the sides of the container. In this case, the containers cannot be stacked. These container units are kept in separate locations to ensure they are not damaged during shipment.


Likewise, open top shipping containers are placed in different locations to prevent accidental stacking in container yards. Only forklift trucks or vertical stacking cranes can be used for mobile OT units with cargo glued to the roof.
