Bending Steel Sheet Metal

Choose a bend radius that matches your minimum bend.

Bending steel sheet metal.

Clamping your sheet metal to the straightedge is a must. Hot metal forming offers tighter bend radii in high carbon steel in degrees that might break the material in cold forming. If you have any questions or want to discuss your design contact us. Mild steel 1 16 ga.

Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. A cutout or the edge of your flange to your bend. Determine your minimum bend by measuring the distance from your closest feature i e. Stainless steel 1 14 ga.

This is done through the application of force on a workpiece. Stainless steel 1 20 ga. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance keep in mind that some metals are more brittle than others. Mild steel 1 brake shear slip roll 1 metal forming 1.

Most sheet metal materials will conform to the calculations. Otherwise the sheet metal is almost certain to shift as you bend it resulting in a bad bend. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. The process delivers highly accurate forming maintenance of thickness and tremendous finished component strength.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Bending a brittle metal beyond its limits could cause the metal to snap and break. Sheet metal calculator bend allowance equations and calculator. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.

The following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. This page also includes a link to a on line sheet metal bend allowance calculator.
