(a) forming a shell that defines a cavity, the shell comprising a base wall, opposed side walls and opposed end walls that define the cavity, wherein forming the shell comprises:
forming two separate mirror-image components and connecting the components together to form the base wall and the opposed side walls, wherein each of the two separate mirror-image components of the base wall and side walls are formed by folding a sheet of steel strip/plate along the length of the sheet to form one half of the base wall and one of the side walls, and
forming the end walls of the shell as separate components, and connecting the end walls to opposite ends of the base wall and the opposed side walls to form the shell, and
