Sheet Metal Bending

High quality sheet metal comes from high quality metal. Effective refining techniques, along with a sound sheet metal rolling process should close up vacancies, break up or eliminate inclusions and provide a sheet metal product with a smooth surface. Edge treatment such as trimming, or fine blanking, can improve edge quality.

Rolling (metalworking) - Wikipedia

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known as hot rolling. If the .

Hot rolled end temperature is 800 ~ 900 ℃, generally cooling in the air, so hot rolling state is equivalent to normalizing treatment. Most of the steel is rolled in hot rolled. Due to the high temperature, the surface of hot rolled steel produces a layer of oxidation sheet, thus has certain corrosion resistance, can be stored in the open air.
