Bending Steel Sheet Metal

Clamping your sheet metal to the straightedge is a must.

Bending steel sheet metal.

This is done through the application of force on a workpiece. 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 following illustration shows the equation calculation for determining the bend allowance when forming sheet metal. Most sheet metal materials will conform to the calculations.

A cutout or the edge of your flange to your bend. Mild steel 1 brake shear slip roll 1 metal forming 1. Stainless steel 1 20 ga. Bending a brittle metal beyond its limits could cause the metal to snap and break.

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 2 12 ga. Hot metal forming offers tighter bend radii in high carbon steel in degrees that might break the material in cold forming. Mild steel 1 16 ga.

If you have any questions or want to discuss your design contact us. The process delivers highly accurate forming maintenance of thickness and tremendous finished component strength. Otherwise the sheet metal is almost certain to shift as you bend it resulting in a bad bend. This page also includes a link to a on line sheet metal bend allowance calculator.

As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Choose a bend radius that matches your minimum bend. If you re bending 0 020 thick material use a 0 020 radius. Determine your minimum bend by measuring the distance from your closest feature i e.
