Swept Flange versus Miter Flange

Although Swept Flanges and Miter Flanges can appear very similar, one very important difference is that the corners of Swept Flanges are joined together continuously—that is, they are not mitered (trimmed in order to fit together). This means that there are no bend relief cuts in the corners (see Figure 5.3) and they are rounded.

The difference can be seen even more clearly in the flattened versions of both parts. The version made using the Swept Flange (shown on the left-hand side of Figure.5.4) has no cuts in the corners and so would have to be made using a process such as stamping and probably would require specialist tooling. By contrast, the Miter Flange version (shown on the right-hand side of Figure 5.4) has cut corners. These could be created using a generic tool such as a Press Brake and so would probably be easier and...
