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.

Compound bends sheet metal.

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. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. Also known as edge rollers these tools slide back and forth along edges to create even bends. Unlike benchtop sheet metal tools these shapers are portable so they re often used on site by roofers.

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. With a single tool create both sharp creases and soft curves along the edges of sheet metal. The force must exceed the material s yield strength to achieve a plastic deformation.

Use 1 8 markings to set up precise bends. How to bend sheet metal without a brake. This is done through the application of force on a workpiece. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart.

As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape.
