Abstract: The invention provides a modular shelving unit comprising at least two upright members and at least two shelf elements which engage oppositely spaced upright members to form a shelving structure. The component upright members and shelf elements are made of a latticework, preferably of welded wire, which is secured at two opposite edges in support beams. The support beams of the upright members provide vertical structure for the unit, and the support beams of the shelf elements provide structure therefor and means for connecting the shelf elements to the upright elements.
