Bending Steel Sheet Metal

This page also includes a link to a on line sheet metal bend allowance calculator.

Bending steel sheet metal.

Mild steel 1 16 ga. Bending a brittle metal beyond its limits could cause the metal to snap and break. Sheet metal calculator bend allowance equations and calculator. If you have any questions or want to discuss your design contact us.

Stainless steel 1 20 ga. To clamp efficiently lay your sheet metal on the top surface of your straightedge with the drawn line perfectly aligned with the outside edge of the sheet metal. If you re bending 0 020 thick material use a 0 020 radius. Otherwise the sheet metal is almost certain to shift as you bend it resulting in a bad bend.

The process delivers highly accurate forming maintenance of thickness and tremendous finished component strength. Mild steel 2 12 ga. Most sheet metal materials will conform to the calculations. Choose a bend radius that matches your minimum bend.

Clamping your sheet metal to the straightedge is a must. Sheet metal bending methods design tips k factor bending is one of the most common sheet metal fabrication operations. Hot metal forming offers tighter bend radii in high carbon steel in degrees that might break the material in cold forming. Stainless steel 1 14 ga.

For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. A cutout or the edge of your flange to your bend. Mild steel 1 brake shear slip roll 1 metal forming 1. 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.

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