1 THE GLOBAL WORLD LEADER MARKET IN LEADER NON-CONTACT IN MEASURING MEASURING SYSTEMS SYSTEMS Non-Contact Measurement for the Aluminum Industry WIDTH THICKNESS FLATNESS SURFACE

2 Taking Quality to New Dimensions IMS Multi-Channel Thickness Profile Measuring Systems set the standard for excellence in measuring any strip dimension, including: > Center Thickness > Crown > Material Contour in Transverse Direction > Material Position > Thickness Profile > Wedge > Width These simultaneous stereoscopic multi-channel (SSMC) solutions are ideal for use at the exit of hot strip finishing mills. By using SSMC Thickness Profile Measuring Systems before trimming occurs, manufacturers can meet customers most demanding quality requirements. Key features include: > Single Value for Thickness Cross-Profile Displayed as Data Pair Consisting of Thickness Value & Corresponding Transverse Position > Strip Contour Evaluated by Determining Strip Thickness Differences based on Signals of Adjacent Measuring Channels > Wedge/Crown Values Derived from Reference Positions of Trimmed or Untrimmed Strip Edges > Strip Width Evaluated from Data Supplied by Measuring Channels in Edge Area & Determined Radiometrically If consistency of strip thickness measurements has been difficult to achieve, SSMC systems are up to the challenge.

3 How Flat is Flat? At an affordable price, the IMS-Camera Cluster Systems (CCS) Flatness Gauge is easy-to-use and offers a degree of accuracy not found in other flatness measuring systems. Our camera cluster technology features 16 cameras per each 300mm segment, and cameras may be added proportionally to strip width. Radar Width Gauges Offer Long-Distance Reliability The Radar Width Gauge is ideal for highly accurate slab width measurements under the harshest conditions, and from almost any distance. The system consists of two measuring devices, with each one containing a sensor and antenna. The gauge is calibrated to measure the distance between the device and slab/ingot edge to determine whether plate width meets customer specifications. Ideal for roughing and breakdown mills. The Radar Width Gauge offers many advantages, including: > Long Operating Life > Low Maintenance > Compactness > Moderate Cost If x-ray and optical measuring systems have been challenged by your environment, a Radar Width Gauge may be the ideal solution. Other significant features & benefits are: > Highly Accurate, Real-Time Monitoring > Takes Precise Reads of All Surfaces Independent of Strip Vibration > Ideal for High-Speed Processing Lines (Cut-to-Length, Coating) > Provides High-Resolution Images of Strip Cross-Direction > Reduces Process Disruptions, Equipment & Scrap > Compact, Lightweight & Easy to Install > Compatible with MEVInet-Q Quality Data Management System IMS CCS Camera Cluster System Accuracy in height direction Sampling rate Permitted strip fluctuation range Distance between strip & camera laser unit Measuring zones Strip width Strip thickness Performance Specifications 0.1mm (2 sigma) up to 1kHz* 100mm (Standard) Higher value on request Appx. 450mm 200 fibers per meter (Standard) Higher value on request Not limited Not limited *Depends on the material surface

4 Achieving Excellence in Strip Width, Edge Crack and Hole Measurement Our strip width measurement systems are ideal for cold processing environments and slitting lines. Using infrared light, this latest optical measuring technology gives you real-time, point-to-point measurements that help to ensure strip quality. In addition to measuring width, the gauge can evaluate edge crack, hole/pinhole size and strip contour. Its key features & benefits include: > Low Maintenance > Long Operating Life > No Moving Parts > Highly Accurate > Compact & Lightweight > Monitors for Dirt > Unaffected by Ambient Light Width/Slit Strip Width Measuring System Measuring Accuracy (online) Measuring Accuracy (offline) Sampling Rate Distance between Camera & Strip Distance Between Strip & Backlight Passline Deviation Strip Width Strip Thickness Slit Strip Width Measurement Distance between Slit Strips Slit Strip Widths better than +/ mm (2σ) better than +/ mm (2σ) 28 khz 350 mm or 800 mm 150 mm mm +/- 5 mm at 350 mm +/- 10 mm at 800 mm Min. 200 mm Max mm No Limit 1 mm 3 mm

5 POWERED BY PEOPLE. MEASURED BY IMS. Compact X-Ray Thickness Gauges for Cold Mills & Service Centers The IMS line of X-Ray Thickness Gauges are precise, reliable and intelligent measuring systems. They re manufactured in a state-of-the-art production facility at our North American headquarters near Pittsburgh and set new standards for precision in non-contact measurement. Key characteristics & advantages are: > 99.9% Accuracy > Affordable & Time-Tested > Modular Design Easily Retrofitted to Existing Lines > Remotely-Mounted Control Box (within 160 ft. (50m) of gauge) > Lower Statistical Noise than Isotope Gauges > No Standards Magazines Throat Depth 49 (1250mm) / 67 (1700)* Throat Depth 72 (1850) / 90.5 (2300)* Throat Depth 96 (2450) / 114 (2900)* *XR-XT Gauge with higher extended thickness range. Specifications & Performance Data To keep controls in top working order by minimizing their exposure to mill conditions, the control box can be mounted up to 50m (164 ft.) from the gauge.
