A spool comprising flanges fabricated from corrugated material connected by a central core and reinforced using metal plates. The flanges consist of at least two pieces of corrugated material fixed together in an orientation such that the corrugations angularly cross each other. For two pieces of corrugated material, a 90.degree. angle of cross has been found particularly beneficial.
