At least a portion of the plurality of slats are asymmetric slats each having an asymmetrically bent or curved shape in a cross-section perpendicular to the longitudinal direction of the slats. The asymmetric slats are each provided with a first plate part and a second plate part, wherein the first plate part corresponds to a long side of a cross-sectional shape perpendicular to the longitudinal direction, and the second plate part corresponds to a short side of said cross-sectional shape.
