Compound Bends Sheet Metal

Bending is one of the most common sheet metal fabrication operations.

Compound bends sheet metal.

Also called elevation and plan view curve or camber and sweep or hard way and easy way compound bends are commonly used in canopies arched roofs on curved steel buildings and domes. Unlike benchtop sheet metal tools these shapers are portable so they re often used on site by roofers. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. With compound bending a steel member is bent along both its strong and weak axes.

How to bend sheet metal without a brake in 4 different methods with minimal or homemade tools. Use 1 8 markings to set up precise bends. This is done through the application of force on a workpiece. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance.

The force must exceed the material s yield strength to achieve a plastic deformation. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. With a single tool create both sharp creases and soft curves along the edges of sheet metal. Unlike helical bending the material is not also being twisted while changing planes.

Sheet metal and plate metal can be bent into a compound curve that matches the needs of any project. The steel bending of many shapes including angle tube beam bar channel sheet and plate can be formed into compound curves that are true and plumb.
