Cold Roll

forming, is a type of rolling involving the continuous bending of a long strip

of sheet metal (typically coiled steel) into a desired cross-section. The strip

passed through sets of rolls mounted on consecutive stands, each set performing

only an incremental part of the bend, until the desired cross-section (profile)

is obtained. Roll forming is ideal for producing constant-profile parts with

long lengths and in large quantities.

Roll

forming machines are available that produce shapes of different sizes and

material thicknesses using the same rolls. Variations in size are achieved by

making the distances between the rolls variable by manual adjustment or

computerized controls, allowing for rapid changeover. These specialized mills

are prevalent in the light gauge framing industry where metal studs and tracks

of standardized profiles and thicknesses are used.
