Folding Sheet Metal Edge

During seaming two sheet metal parts or two edges of the same sheet metal are joined in an interlocking manner.

Folding sheet metal edge.

Versatile compact 18 inch 46 cm drip edge folding tool makes quick bends along the drip edge of flat pan standing seam metal roofing panels. Folding tools are ruler like lengths of metal that are placed against the sheet metal and then manually bent with the metal. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. According to the din 8580 series of standards this process belongs to subgroup 4 5 joining by forming and is specified by din 8593.

Similar to tucking the corners of a bedsheet these benders twist and wrap the metal into triangle shaped folds to form corners. Fold corners in flat metal sheets to create your own bin boxes drip pans and other three dimensional objects. The force must exceed the material s yield strength to achieve a plastic deformation. Economy sheet metal benders make bends up to 90 in metal sheets.

In sheet metal hems are used to create folds in sheet metal in order to stiffen edges and create an edge safe to touch. Hems are commonly used to hide imperfections and provide a generally safer edge to handle. This is done by simultaneously folding or pressing the prepared and fitted edges. Bending is one of the most common sheet metal fabrication operations.

Hems are most often used to remove a sharp untreated edge and make it safe for handling. Drip edge folding tools are folding tools with an attached handle for additional leverage and strength when bending sheet metal on bench or on installed overhead panels.
