They were manufactured hollow. If they were solid metal, that would be crazy heavy and totally unnecessary and unimaginably expensive. If they want to get rid of the 'roar' they fill the hollow area with something that reduces the noise. Ive hear they use sand, but that also seems like it would add a lot of weight.
