Sheet metal production begins with the precise melting of the chosen alloy—whether it’s copper, aluminum, steel, or titanium. At its melting point, the metal becomes liquid, ready for the next stage: pouring.
Hot liquid metal is poured from a crucible into a rectangular mold. As the metal cools, it solidifies into a uniform ingot—a dense, homogenous block that will later be refined.
The ingot then undergoes pickling, a chemical treatment that removes surface impurities such as rust, scale, and other contaminants. This step ensures a clean surface and prepares the metal for deformation.
Finally, the cleaned ingot is fed through a series of rollers in the rolling and annealing stage. Successive passes flatten the ingot, progressively reducing its thickness. Because each pass hardens the metal, the process includes controlled annealing—heating followed by cooling—to restore ductility and keep the sheet pliable for further rolling.
Sheet metal can be crafted from a variety of metals, each selected for specific performance traits:
To meet specific functional requirements, sheet metal may receive additional treatments:
From automotive panels to household appliances, from industrial piping to high‑precision medical instruments, sheet metal’s versatility and adaptability make it indispensable in modern manufacturing.
