Double rows stud roll forming machines continuously form structural metal studs with dual protruding ridges from steel coil feedstocks. The machines utilize a series of roller dies to progressively shape flat strip substrate into C or Z section studs with vertical web and uniform horizontal flange ridges running along both sides of the member length.

This guide covers standard offerings, the roll forming process basics, machine component details, operational guidance, customization possibilities, supplier comparisons, selection factors, pros vs cons considerations, and commonly asked questions regarding double rows stud roll forming line equipment.

The systems integrate with auxiliary uncoilers, feed tables, levelers, saws and exit conveyors.

How Double Row Stud Roll Forming Works

The roll forming process utilizes shaped roller dies to incrementally cold form continuous flat strip stock into final stud profiles with two protruding flanges along both sides of the vertical web as it passes through the production line (Figure 1). Steps include:

1. Feeding line level sheet into system from coil
2. Progressively cold roll forming with upper/lower roller dies
3. Bending narrow horizontal flanges uniformly up from web
4. Calibrating final profile to intended dimensions
5. Shearing cutoff studs to length upon exit
6. Accumulating or coiling finished parts

FAQ

What thickness range can double rows stud roll formers handle?

Standard models process material thicknesses from 0.75mm – ~5mm hot rolled coils and galvanized sheet products. Thinner gauges depend on required bend radii while thickness equates to drive power.

How fast do these machines operate?

Typical production line speeds averaging 10-15 meters per minute enable rapid processing suited for most structural metal stud volume requirements. Appropriate feed power settings prevent tearing.

What expertise is recommended for operation?

Some automation eases skill requirements, however mechanical fabrication experience proves helpful for optimizing output through procedural adjustments and troubleshooting quality issues.
