What is cold roll forming
Discover Sika’s cold forming process for custom metal profile production
Cold roll forming is a modern and highly efficient technology used by Sika in the production of custom metal profiles. This process involves shaping steel strips at room temperature without the use of heat through a series of precisely shaped rollers that gradually form the desired geometry.
This continuous process enables the production of profiles with various cross-sections, millimetric precision, and customized features. It is ideal for a wide range of industrial applications, including the construction and automotive sectors.
Sika employs production lines designed to integrate all secondary operations such as punching, cutting, and marking directly inline, eliminating the need for additional processes and significantly reducing both time and production costs.
Main stages of cold roll forming according to Sika
Sika’s production process is designed to ensure efficiency and top quality. The key stages include:
- Coil Preparation: The metal strip is unwound and leveled in preparation for forming.
- Straightening: The material is corrected to eliminate curvature or surface defects.
- Pre-punching and Cutting: Holes and cuts are made as required, without interrupting the flow.
- Roll Forming: The strip passes through specialized rollers that shape it into the final profile.
- Continuous Welding: For closed profiles, high-precision welding ensures structural integrity.
- Final Straightening and Bending: Additional adjustments and custom bending are performed.
- Cutting and Secondary Operations: Profiles are cut to size and completed with optional finishing.
- Unloading: The finished product is collected and prepared for the next step in the supply chain.

The cold profiling process
The process begins with the coiler, which continuously feeds the sheet metal from the coil, ensuring a constant flow for the production of cold rolled profiles.
The process begins with the coiler, which continuously feeds the sheet metal from the coil, ensuring a constant flow for the production of cold rolled profiles.
At the heart of the process, the profiling machine uses pairs of shaped rollers that progressively deform the sheet metal, obtaining precise sections that conform to the design of the cold profile.
High-frequency welding allows profiles to be joined to obtain strong and precise joints, ideal for closed profiles.
Post-profiling, these tools refine the profile, correcting any imperfections and defining specific curvatures or angles.
Before the material enters the subsequent stations, the cutting system intervenes to shorten the sheet metal according to pre-established measurements, ensuring that each cold roll forming produces perfectly sized pieces.
Finally, the finished profiles are separated into cut-to-size pieces using an unloading unit, completing the process and preparing the cold-rolled profiles for further processing or shipping.
