What is the required thickness for roof panel inserts and patches?

The required thickness for roof panel inserts and patches is 2mm, as this specification is based on maintaining structural integrity and ensuring the durability of the repair. A thickness of 2mm is sufficient to provide the necessary strength and resistance against various external factors such as weather conditions and physical stress that may occur during transportation. Using this thickness helps to ensure that the repaired area can withstand the same loads as the original structure, thereby contributing to the overall safety and performance of the dry van.

Thicker materials, while potentially stronger, may not be needed for the effective repair of roof panels, and utilizing a thickness greater than 2mm could unnecessarily increase weight and complicate the repair process. Similarly, using a thickness less than 2mm might not provide adequate support, potentially leading to failures in the repair over time. Therefore, the 2mm requirement strikes a balance between performance and practicality in the context of dry van repairs.
