Black plate can be applied as a base plate, and is often used as the main material in steel construction joints by welding it, especially if there is a problem where the material being used is not enough or there are certain parts that are in a difficult position. Generally also often used as a material for making ships, tubes, vehicle body, etc. Black plates can also be used as road bearings for heavy vehicles. Another use is as a medium so that it can be an access road for mobilizing cranes or excavators and several other vehicles in order to drive to the field properly.
