| 摘要 |
An improved plastic blow-molded panel structure is shown and described that is lightweight and provides superior resistance to sagging, warping and creeping under high stress loads, especially when used in a horizontal position. The disclosed panel structure includes a combination of transverse or lateral beams extending from the second panel towards the first panel and, in certain embodiments, a plurality of transverse ribs disposed within the lateral beams. The disclosed shelving units may be fabricated from conventional blow-molding processes. |
