An outer bend radius is cold formed in an outer position within a final arc of the angled corner with an outer bend radius male die member. A central bend radius is cold formed in a central position spaced from the outer position and within the final arc of the angled corner with a central bend radius male die member. An inner bend radius is cold formed in an inner position that is spaced from the outer and central positions and the inner position is within a final arc of the angled corner with an inner bend radius male die member. The angled corner is transferred between each of the bend radii male die members using a continuous advanced high strength metal sheet in which the angled corner is formed.
