Operations like bending, folding, and crimping can increase the strength of sheet metal without changing its thickness.

• Bending: This process involves bending the sheet metal along a straight line to increase its strength.

• Folding: Folding the sheet metal creates multiple layers, increasing its strength.

• Crimping: Crimping involves creating small indentations or folds in the sheet metal to increase its rigidity.

• Rolling: R...read more
