Finishing-stand gauging and AGC feedback across steel mills worldwide.

GGC thickness and width gauges run on hot strip mills, cold rolling mills, temper mills, and plate lines from continuous casters through skin pass. Our 200 kV and 100 kV X-ray heads are the production standard on tandem cold mills for sub-2 ms AGC feedback.

Tandem cold mill thickness control

A typical application: a Perfecta primary gauge at the exit of a multi-stand tandem cold mill, replacing a legacy isotope gauge. Tighter exit-thickness control and faster AGC feedback reduce off-gauge length on every coil.

Tighter tolerance from the first coil onward, with AGC feedback the mill team can trust.
