The measurement standard of the world's rolling mills and beyond.
Since 1953, KELK has built the force, tension, and geometry measurement systems that let steel and aluminum producers run faster and tighter, with less downtime. Today that heritage extends into a full laser-optical inspection platform.
Founded in Toronto in 1953, KELK brings VPG's precision-sensing strategy to one of our large end markets: metals production. Several thousand systems back an installed base spanning steel and aluminum mills worldwide and fuel the expansion into optical measurement systems with its Alpha line.
