Curled Sheet Metal

Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes countless everyday objects are fabricated from sheet metal.

Curled sheet metal.

Item 241548 model 11766. Curling is a sheet metal forming process used to form the edges into a hollow ring. Extremely thin sheets are considered foil or leaf and pieces thicker than 6 mm 0 25 in are considered. Thicknesses can vary significantly.

Curling is different than a tear drop hem because in a curl the edge finishes inside itself where a hem leaves the initial edge exposed. The curled edge provides strength to the edge and makes it safe for handling. Sheet metal is metal formed by an industrial process into thin flat pieces. Curling can be performed to eliminate sharp edges and increase the moment of inertia near the curled end.

Other parts are curled to perform their primary function such as door hinges. Proper sheet metal curl. Hillman 24 in x 24 in cold rolled steel solid sheet metal. Curls may also function to act as stiffeners at the edges by increasing the effective thickness at the ends.

This is accomplished through increasing the moment of inertia at the ends.
