Roll forming is an ongoing bending procedure in which a lengthy strip of sheet steel (normally coiled metal) is passed via rolls mounted on consecutive stands, each set executing only an incremental component of the bend, till the preferred cross-part profile is obtained. Roll forming is perfect for generating continuous-profile components with long lengths and in big quantities.
Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. A solution called pickle liquor, which contains strong acids, is used to remove the surface impurities. It is commonly used to descale or clean steel in various steelmaking processes.

Reducing can be done with extreme pressure lubricants at speeds over 7,000 FPM. There are many mills that run at very low speeds when reducing expensive alloys such as beryllium, copper, tantalum, and gold and use little or no lubricant or coolant. Many lubricants are good for extreme pressure, but they can also act as a coolant. Water is still considered one of the greatest liquid coolants. An extreme pressure lubricant mixed with water makes a good lubricant.
