Which description best matches a formed edge?

• A. Edges created by bending the sheet metal
• B. Edges formed from the sheet metal itself
• C. Edges created by adhesive bonding
• D. Edges that require finishing after installation

Answer: (B)

Formed edge means the edge comes from shaping the sheet metal itself, not from attaching or adding something to it. The edge is a feature of the metal after forming, created by bending, hemming, or other forming actions, rather than being produced by bonding another piece or by finishing after installation. So the best description is that the edge is formed from the sheet metal itself.
