Bending galvanized sheet metal over gable.
Metal is placed cantilevered over the edge of the lower die similar to the setup in edge bending.
The flashing should overlap the edge of the roof by one inch to help direct water.
The solution is to have a radius on the tool that you ll be using to bend the metal.
It helps direct water away from the meeting points and keeps the roofing dry.
Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
Refer to the chart for values for folder as well as various press brake tooling combinations.
Even on malleable materials you can end up cracking the metal at the bend or weakening it to the point where it ll break with minimal force.
Unlike in edge bending with rotary bending there is no pressure pad.

Bending the galvanized steel can help you mold it into shapes appropriate for your project.
To bend your sheet metal with a vise and hammer you will need.
Bend the flashing into a v shape to fit over the top roof ridge and the corners where the panels meet.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
Bending is one of the most common sheet metal fabrication operations.
Geometry of tooling imposes a minimum bend dimension.
Flashing is metal trim that fits over joints where two sections of roof meet.
The groove on the cylinder is dimensioned to create the correctly.
Force is transmitted to the punch causing it to close with the work.
This is normal for galvanized steel and with the cathodic properties of the zinc coating is acceptable for a part bent after galvanizing.
This is done through the application of force on a workpiece.
The force must exceed the material s yield strength to achieve a plastic deformation.
The diagram shows one such mechanism.
When galvanized steel is bent after the coating has formed there is no issue with cold work but there can be an issue with the coating cracking or crazing in the area of the bend.
