The 5 main types of hemming created in sheet metal bending include flat hem, open hem, rope hem, teardrop hem and rolled hem. Hemming is a method of bending sheet metal wherein the edges of the sheet metal are bent inwards to strengthen the edges. Solera Metal Fabrication, a major metal fabrication shop offering laser sheet metal cutting, rolling and tube cutting services, explores these 5 types of hems in this blog.
What Are Types Of Hems Created Using Sheet Metal Bending?
Flat Hem
A flat hem is the most commonly made form. It involves bending the edges of the sheet metal completely onto itself, leaving no gap between the bends.
Open Hem
Open hem is a softer form of hemming wherein the edge is bent inwards, but not completely. It has a soft outer edge and some space in between the bent metal. This is typically used in products to create handles or holds.
Rope Hem
Rope hem is another form of hemming wherein the flange of the metal is bent at an angle greater than 180 degrees. It involves two parts instead of just the sheet metal to create a more secure joint.
Teardrop Hem
A teardrop hem in a bending sheet metal involves creating a bend at 90 degrees. Then, the bent edge is rolled into a teardrop shape to create a smooth, long-lasting edge.
Rolled Hem
Lastly, the rolled hem is similar to a teardrop hem in the initial stage. The edge of the sheet metal is bent to 90 degrees. But then, instead of giving it a teardrop shape, the hem is rolled into itself to create a rounded edge.
