Abstract
A unitized package of a plurality of drums filled with coiled welding wire, each drum comprising a cylindrical body, a top rim, a bottom rim and a bottom circular wall fixed to the bottom rim and having a peripheral shape. The package comprises: a spacer between the cylindrical bodies, a first band stretched around the plurality of drums adjacent the top rim, and a second band stretched around the plurality of drums adjacent the bottom rim wherein each drum has a riser network permanently fixed to the bottom wall and formed from thin elongated elements with a given height greater than about two inches. A lower support plate is permanently attached to the riser network and is parallel to the bottom wall of the drum to provide an integral pallet on each drum.
