[Problems to be solved by the invention]
In this case, a thin metal plate and a foamed resin can provide a resource-saving base beam having a structural strength comparable to the above-mentioned extruded aluminum material. The upright fin is located at the joint of the metal shell on the metal sheet side end of the molded shell, and is formed by bending and stacking the sheet metal on one of the base wall components on the joining side. The standing strength is likely to decrease, and the load resistance to the load in the depth direction may be inferior. For example, the required load resistance when an external force such as a fence or a handrail leans on a person or the like may be reduced. There is a possibility of shortage, which is a factor that hinders practical use as a base rail.
