MG5 cold rolling thickness gauge for consistent coil processing
The MG5 system delivers accurate, real-time cold rolling thickness and width monitoring, giving cold mills the data they need to maintain across each pass. With stroke lengths of 24 in, 48 in, 80 in, and 86 in, MG5 fits a wide range of mill setups and installs with minimal disruption.
By enabling continuous cold rolling thickness monitoring, MG5 helps operators fine-tune roll pressure and speed to hit target thicknesses more consistently—improving pass scheduling, reducing over-rolling, and minimizing downstream issues like buckling or poor flatness. It reduces reliance on manual checks, cuts scrap, and ensures coils meet final spec before moving to finishing or annealing.

How MG5 enables automated cold rolling thickness measurement on your line
Seamless installation for cold rolling lines
- Easy Mounting & Integration – MG5 cold rolling thickness gauge installs directly onto cold rolling lines with minimal modifications, making it easy to upgrade existing setups without extended downtime or major reconfiguration.
- PLC & Network Compatibility – MG5 integrates with your control system, enabling real-time cold rolling thickness monitoring, to help operators detect deviations early and keep rolling conditions stable.
- Robust & Scalable Design – Available in 24 in, 48 in, 80 in, and 86 in stroke lengths, MG5 adapts to various coil widths and materials, supporting accurate cold rolling thickness and width monitoring across a wide range of production requirements.
- Automated Operation – MG5 enables continuous cold rolling thickness monitoring, reducing manual inspection, cutting material waste, and improving quality consistency—ensuring your output meets customer specifications.

How MG5 performs cold rolling thickness monitoring
1. Strip Scanning Begins
The Gauge&Go App continuously scans the incoming strip on the cold rolling mills, capturing real-time data for thickness and width measurement.
2. Real-Time Cross-Sectional Measurement
The laser sensors move across the strip, capturing thickness data at multiple points.
3. Live Data Processing
The system calculates key parameters such as thickness profile, min/max thickness, standard deviation, and width.
4. Instant Display & Analysis
Data is visualized on an easy-to-read dashboard, providing operators with real-time insights.
5. Automated Alerts & Reports
Any deviations from set tolerances trigger alerts, allowing for quick adjustments.
Mate Gauge solves your challenges in cold rolling thickness measurement
Manual checks cause production delays and inefficiencies?
Sampling methods slow down the process and fail to provide full coverage. Mate Gauge automates thickness and width measurement across the entire coil, reducing reliance on manual inspections and ensuring every section meets customer specifications.
Over-rolling to avoid under-thickness adds cost?
Without precise data, operators compensate with excess reduction. Mate Gauge eliminates guesswork, helping maintain target thickness without wasting material or energy.
Thickness variation due to roll wear and mill deflection?
Roll pressure inconsistencies cause uneven thickness across and along the strip. Mate Gauge continuously monitors thickness across the strip width, helping teams detect profile issues early and reduce variability.
No clear traceability of coil quality over the entire width
Without data capture, it's difficult to prove compliance or identify process issues post-production. Mate Gauge records and logs coil thickness across the width and length, providing a clear audit trail for quality assurance and customer reporting.
