How are the flooring materials typically installed in a container?

The flooring materials in intermodal containers are typically installed by being screwed or bolted to cross members. This method provides a secure attachment that ensures stability and durability, which is essential for the weight and movement of cargo during transport. The flooring must withstand significant stress, especially when containers are loaded and unloaded. By fastening the flooring with screws or bolts, the integrity of the floor is maintained, helping to prevent issues such as warping or detachment, which could compromise safety and cargo security.

Other methods such as welding would be less feasible due to the need for flexibility in the design and maintenance of containers. Glue, while it might offer some stability, does not provide the necessary strength needed to endure the physical demands on the flooring during transport. Using zip ties is an unsuitable choice as they lack the strength and durability required for securing heavy flooring materials against the rigors of shipping and handling.
