What is the maximum allowable deformation for a roof panel outward on tube type top rails?

The maximum allowable deformation for a roof panel outward on tube type top rails is considered to be 100mm. This standard is important as it ensures proper structural integrity and functionality of the dry van during use. Excessive deformation can compromise the load-carrying capacity, potentially leading to issues such as leaks, structural damage, or compromised safety during transportation.

In the design and maintenance of dry vans, adhering to this limit is crucial to prevent any operational failures. Therefore, knowing this specific measurement helps in ensuring the equipment is kept within safe operational parameters, thus enhancing longevity and reliability.
