Sheet metal Wikipedia

Sheet metal is metal formed by an industrial process into thin, flat pieces. 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. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm ( in) are considered ...

Introduction to Rolling Process Assets

from the rolls, the process is called simple rolling. Hot and Cold Rolling Processes From metallurgical point of view, rolling process can be classified under two broad categories, namely (i) hot rolling and (ii) cold rolling. Hot rolling In hot rolling the material is rolled at a temperature higher than its recrystallization temperature.
