More than just the solid core: Profiles made from high tensile steel
That what has been taken away from the boom’s weight is returned in efficiency. The clever lightweight design makes use of the material where it makes sense. For instance, aluminium for weight reduction at the outer boom sections of the Super-S2 boom, but not however, in the middle of the boom. There, high tensile steel is necessary so that the boom is kept rigid and in line and so spray errors due to vibration are prevented.
