Working Principle
Roll formers shape flat steel strip into structural sections by incrementally bending the material through a series of stations:
Light Steel Roll Forming Process Steps
- Uncoiling – Sheet coil is unwound and entered into the line
- Feeding – Powered rolls advance the strip
- Punching – Holes punched if needed
- Forming -Contour rolls progressively shape the profile
- Cutting – Formed section cutoff to length by shear
- Exit – Conveyor collects finished parts
Precise servo electric actuation coordinates the material feed, punching and cutoff motions.

FAQs
What thickness range can be reliably roll formed?
Standard gauges from 16 gauge (1.6 mm) to 26 gauge (0.5 mm) can be formed on most roll formers. Specialized machines handle up to 3/16″ (4.8 mm) plate.
How long does it take to changeover to a new profile?
With tooling staged and machine preparations complete, typical profile changeover takes 30-60 minutes. Complex changes require more time.
What determines the maximum forming speed?
Main constraints are material thickness, number of bending stations, overall machine length, and cutoff method. More stations and thicker material restrict feed rate.
How often do roll forming rollers need replacement?
Sharpening or replacement is typically needed every 4-6 months depending on hours run and maintenance. Better roll materials, coatings and lubrication extend service life.
Can a roll former make creative tapered or curved profiles?
Yes, specialized machine designs with articulating heads or swirling stands can produce tapered, conical or helical formed sections.
How should I handle and store roll formed parts after production?
Banding bundles together, using protective end caps, and keeping dry helps maintain straightness. Avoid outside storage which can lead to corrosion.
Conclusion
Automated light steel roll forming machines improve efficiency, throughput and consistency for high volume structural section production. Their flexible and scalable configurations form diverse profiles from coiled steel. By understanding the technical considerations, manufacturers can invest in light steel roll forming systems that boost productivity versus manual methods.
