Core Product Lines

One Measurement Architecture, Cast to Coil

KELK designs strain-gage force sensors and optical dimensional gaging as a single measurement architecture — so mill control systems get consistent, high-accuracy data from cast to coil.

●

Roll Force — Load Cells

Precision load cells that measure the force applied to work rolls, providing accurate data for mill setup, control, and product quality.

◯

Optical — Width Gage 

Non-contact optoelectronic gages (ACCUBAND) that measure strip width and centerline deviation across hot and cold rolling applications, using CCD camera technology built to withstand harsh mill conditions.

5 Year Rollmax Warranty

The Rollmax Warranty

KELK Rollmax Load Cells are guaranteed against failure of any kind, however caused, for five full years — not just defects in material or workmanship. Mills that upgrade from other brands can calculate, in advance, what they’ll save in replacement cost alone.

Applications Across the Metal Industry

Specified Into the Process — Not Bolted on After

From hot mill roughing stands to cold rolling finishing lines, KELK measurement systems are built into the process itself.

Hot Strip Mills

Roll Force, Tension & Crop Optimization

Load Cells measure roll force directly at the mill stand, while Looper Load Cell Assemblies derive strip tension for mill control systems. Crop optimization, camber, and hot metal detection systems work together to reduce scrap and improve yield across the roughing and finishing lines.

Cold Rolling & Processing

Non-Contact Measurement for Tight-Tolerance Strip

ACCUBAND width gages and laser thickness systems deliver accurate, non-contact measurement in the tight spaces of tension levelers, tandem mill exits, and slitter/rewinder lines — built for continuous, low-maintenance duty.

Aluminum & Plate Mills

Force & Dimensional Gaging Under Continuous Load

Camber gages, plate outline systems, and the ALUMIVIEW Crop Optimization System give aluminum and plate producers the dimensional feedback needed to hold shape and reduce yield loss across long production runs.

Sensors & Process Control

Rugged Sensors for Mission-Critical Applications

Laser-based thickness, flatness, and contour gaging extend KELK's precision measurement capabilities to camshaft inspection, automotive glass, and other demanding inline process control applications.
