What is beading?

• A. A folded stiffening rib added to a panel to increase rigidity
• B. A rounded edge
• C. A decorative crease
• D. A type of gasket

Answer: (A)

Beading is a folded stiffening rib added to a panel to increase rigidity. By forming a raised ridge along the sheet, the panel gains greater resistance to bending and buckling because the bead increases the section’s stiffness. It acts like a small built-in frame that stiffens the flat surface, which is especially helpful on long panels or around openings. This isn’t just a rounded edge or a decorative crease; those features serve different purposes (rounding edges for safety or aesthetics, decorative creases for appearance). And it’s not a gasket, which is a seal between parts.
