Abstract
A strength-reinforcing metal sheet having repetitive concave and convex features is provided. Concave beads extend in repetitive quadrangular lattice features. A plurality of convex cells are defined between the beads, protrude above the beads, and have repetitive convex features. The upper portion of each of the cells has a pyramidal shape similar to a dome. The uppermost point thereof is formed at an eccentric point offset from the central point of the cell.
