What do you mean by sheet metal flanges?
It means bending. Iron bending
Flanges are between two pipes used to connect a mechanical structure.

Flanges are also called flanges or flanges. The flange is to make pipe and pipe interconnected parts, connected to the pipe end; the flange is also useful in the import and export of equipment for the connection between the two devices, such as reducer flange, I was engaged in the automobile sheet metal flange, and nothing else, industrial metal, such as steel plate bending, cutting etc. also called sheet metal, I probably guess you may be of Turner
