What are the specifications for center support thickness and width?

The specifications for center support thickness and width are critical for ensuring the structural integrity and proper function of dry vans. The standard dimensions of 5mm thickness and 64mm width are designed to provide adequate strength and support during use. A thickness of 5mm is sufficient to handle the loads encountered in typical operations, while a width of 64mm ensures stability and effective load distribution across the van's structure.

These dimensions are established based on testing and industry standards that prioritize durability and safety in cargo transportation. Meeting these specifications helps prevent issues such as structural failure or deformation of the support during transport, which can lead to damage to the cargo and the van itself. This is why the correct answer maintains these standards, ensuring durability while complying with regulatory requirements for dry vans.
