Because the goods are placed on the pallet and loaded into the container, in order to prevent the pallet from moving during the container transportation, the pallet is usually nailed to the floor with iron nails. If other materials, such as steel plates, cannot be nailed into the nail.
There are standards for the size, length, width, thickness, number of layers, materials, etc. of the wooden floor. The wooden floor must also be treated with medicine fumigation, and meet the standards of the Health Bureau.
