What is cold roll forming?

Time: 2020-10-15 From: Xiamen Sinotok Machinery Co., Ltd.

Cold roll forming consists of gradually and continuously forming a steel profile. The method consists initially unrolling the strip of a steel coil, whose width corresponds to the developed of the finished profile.

This succession of rollers is decomposed into a number of operations. Each operation corresponds to a profiling head. Each head is similar to a small rolling mill cage with two shafts, one upper and the other lower, supporting the rollers with conjugate profiles, machined to match the forming they must perform and between which passes the metal strip.These rollers are made of high strength steel and manufactured by us.

The cold roll forming operation does not bring about any substantial modification to the flat product used concerning its thickness and its mechanical characteristics.

The cold forming industry is part of the primary metal processing industry between the steel industry and users.

The cold roll forming advantages are numerous

  • 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.
