Flatbed Trailer Dimensions

Flatbed trailers are the most common type of open trailers. There are many types of items that it can transport, but it is usually used to transport goods that cannot be put in a dry van trailer, such as wood, steel, machinery, etc. According to the different transported goods, flatbed semi-trailers have also evolved into different types.
