What is Cold Roll Forming?

Cold roll forming is a kind of cold bending processing, it is an efficient, effective shaping that delivers tight tolerances on complex profiles.

Cold roll forming is a reliable, proven approach to metal shaping that is ideal for modern applications. This process uses a continuous bending operation where long metal strips, typically coiled steel, are passed through consecutive sets of rolls at room temperature. Each set of rolls performs incremental parts of the bend to produce the desired cross-section profile. Unlike other metal shaping methods, the cold roll forming process is inherently flexible. Secondary processes can also be integrated into a single production line. Cold roll forming increases efficiency while reducing operational and capital costs by eliminating unnecessary handling and equipment.

ProWhat is cold roll forming capability?

Typical cold roll forming mills can accommodate material gauges ranging from .010″ up to 0. 250″ thick. The bend radius is largely determined by the ductility of the metal. However, 180-degree bends are commonly achieved with the right material. Roll forming easily accommodates the integration of secondary operations such as welding, punching and precision laser cutting to optimize production efficiency.

What are the advantages and benefits of cold roll forming compared to other metal forming processes?

  • Development, diversity and complexity of forms that meet all the needs of users.
  • Curvature radius corresponding to the thickness of the metal strip.
  • Lightening the weight of structures by roll forming steels with high elastic limits.
  • Ease of implementation in assemblies with welding, riveting, bolting, gluing.
  • Variety of possible delivery lengths of steel profiles, up to 30 meters.
  • Diversity of surface conditions such as hot roll, pickled, cold rolled, prepainted, and galvanized.
