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.

According to the din 8580 series of standards this process belongs to subgroup 4 5 joining by forming and is specified by din 8593. Folding tools are ruler like lengths of metal that are placed against the sheet metal and then manually bent with the metal. Fold corners in flat metal sheets to create your own bin boxes drip pans and other three dimensional objects. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.

Hems are most often used to remove a sharp untreated edge and make it safe for handling. 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. They have sight holes to ensure the bend is uniform. Hems are commonly used to hide imperfections and provide a generally safer edge to handle.

Bending is one of the most common sheet metal fabrication operations. In sheet metal hems are used to create folds in sheet metal in order to stiffen edges and create an edge safe to touch. This is done by simultaneously folding or pressing the prepared and fitted edges. Two rib reinforced steel plates are permanently welded together to create two folding seams for making 1 inch 25 4 mm and 1 1 2 inch 38 1 mm deep bends in maximum 22 gauge 0 76 mm steel.

Economy sheet metal benders make bends up to 90 in metal sheets. 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.
