Container specifications can be a bit confusing, especially when comparing 42GP, 40GP, 45GP, and 40IQ. Let's clarify the sizes of these containers step by step.Firstly, the term "42GP" refers to a general purpose container with a size of 40 feet in length and a height of 9 feet 6 inches. This is a standard container widely used for various shipping purposes.Next, the "40GP" container is also a general purpose container, but it has the same dimensions as the "42GP," despite the different names. It is also 40 feet long and 9 feet 6 inches high.Moving on to the "45GP," this container is slightly larger than the 42GP/40GP. It is also a general purpose container but with a length of 45 feet and a height of 9 feet 6 inches.Lastly, the "40IQ" container is not a standard container size. "IQ" is not a recognized container specification. It's possible there might be a typo or a misunderstanding here. If you meant a 40-foot container with special purposes or equipment, it would still have the same height as the GP containers, which is 9 feet 6 inches.In summary, the 42GP and 40GP containers are the same size, as are the 45GP and the 40GP. The "40IQ" container's size is not clear due to the unrecognized specification. If you need further clarification or have more specific questions about container sizes, feel free to ask!詳情
