A load-bearing platform is thermoformably molded from a single sheet of thin-gauge resinous material. In pallet-like horizontal orientation, the platform includes four upright planes including 60 degree-angularly intersecting diagonal planes emanating from the perpendicular intersection of longitudinal-plane and a transverse-plane. There is a load-bearing topical-plane including therealong geometrically similar (e.g. circular or hexagonal) topical-shoulders respectively surroundably provided with depending collar-like columns, and which columns along a platform bottom-plane are aptly semi-peripherally connected with platform bottom-shoulders. Respective columns in parallelism with the diagonal-planes and with the transverse-plane are connected with thermally-fused dual-walls upright ribs, each rib being rooted at the bottom-shoulders and having an upright extremity adjacent to topical-shoulders. The thusly arrayed thermally-fused ribs provide linearly and intersectionally arrayed series of ribs-effected-stiffeners to afford unusual strength for moderately topically loaded thermoformed platforms.
