Open Top Containers offer similar storage and transportation functions as ordinary shipping containers, but they may hold much larger things. These containers are typically made of corrugated steel and have a wood floor. Instead of a solid roof, the container's top is open and covered with a robust rubber tarpaulin. Open Top Containers are great for using huge cranes to load scrap metal and wood. They are a special sort of shipping container for things that are too huge to fit into a standard shipping container. They are very safe to use.
