What is the minimum thickness required for the header extension plate and corner protection plate?

The minimum thickness required for the header extension plate and corner protection plate is 3.2mm. This specification is crucial because these components are designed to provide structural integrity and protection to the container, particularly at stress points where the cargo weight is concentrated and where the container may experience impacts.

Using 3.2mm thickness ensures that the plates are strong enough to withstand these forces and provide durability throughout the container's service life. Thicker materials may provide additional strength, but they can also add unnecessary weight and cost to the container. Therefore, 3.2mm represents a balanced choice, ensuring that the plates can perform adequately without compromising the efficiency and economy of the container design.

Other thickness options either exceed the necessary specifications, potentially leading to inefficiencies, or are insufficient to provide the required protection and strength at critical junctions of the container.
