What is the primary material requirement for header extension plate or corner protection plate inserts?

The primary material requirement for header extension plates or corner protection plate inserts is that they must be made of the same material as the old plates. This ensures consistency in strength, durability, and compatibility with the existing structure of the dry van. Using the same material helps maintain the overall structural integrity of the container and fulfills safety and performance standards that have been established for these components.

In addition, employing the same material allows for better integration and adherence to the structural properties of the dry van, reducing the potential for issues such as differential wear or stress concentrations that could arise if dissimilar materials were used. Maintaining material uniformity is also critical for regulatory compliance and helps in upholding repair practices outlined by the International Institute of Container Lessors (IICL).
