摘要

The invention relates to a box-shaped wall panel consisting of sheet steel for a curtain wall on a building. The rims (4,5,6,7), which are bent backwards in an external hydroforming process, have rounded edges and seamless closed corners, the radius of curvature of the latter being a multiple of the radius of curvature of the formed edges.
