Abstract: This invention relates to a steel coil positioning structure which at least comprises a positioning seat made of plastic material. The positioning seat comprises at least one base body and two side seat bodies. The base body has a first surface and a second surface opposite to each other. The side seat bodies each having a ramp thereon are fixed on the first surface. The ramps of the side seat bodies are disposed oppositely and directed to center so as to form a bearing surface for placing steel coil thereon. The second surface of the base body is a flat surface. In this manner, steel coils can be positioned stably on the positioning seat. As plastic material is used, manufacturing becomes convenient and quick, and it consumes fewer time and cost in loading into container without conducting pesticide application and fumigation.
