Beschreibung
Zusammenfassung:	A corrugated sheet of the present invention comprises a top plate. The plate includes at least one multi-surface arc portion, the multi-surface arc portion having a plurality of surfaces connected in sequence, and on one side of the multi-surface arc portion, the included angle between arbitrary two adjacent planes is an obtuse angle, so that the multi-surface arc portion exhibits an approximate arc. The efficacy of the present invention lies in making use of several planes to manufacture a multi-surface arc portion that has a substantially arc shape and shows no deformation and warping and is more convenient to use as compared to the prior art wherein the arc is shaped directly. The viewer is allowed to visually perceive an appearance effect similar to an arc.
