Edge Profile
| Classification | Explanation |
| Mill Edge | Edges as produced, not sheared. No width tolerance applied. |
| Slit Edge | Edges sheared in the width demanded by a customer. |
| Deburred Edge | Edges sheared and trimmed roughly. |
| Round Edge | Edges sheared and trimmed with their endings rounded. |
