The Leveltek stretch leveling process consists of:

  • Uncoiling
  • Stretching
  • Leveling
  • Re-coiling

Leveltek eliminates shape defects such as edge waves, center buckles, quarter buckles, crossbow or oil can, and mandrel breaks. The only measurable effect on the coil is a slight reduction in material width, and a slight increase in length. The changes to physical properties are minimal, and the process is guaranteed not to mark or scratch the surface being stretched.

Leveltek’s stretch leveler has the ability to stretch with the force of 1.25 million pounds, which allows flattening of metals beyond ¼-inch thick, or with yields in excess of 100,000 psi.

Even with materials that can be flattened using other methods, our process provides a higher standard of flatness for critical or special surfaces that are:

  • Bright Annealed
  • Polished
  • Painted
  • Patterned
  • Plated/Coated

Leveltek can process coils in a wide range of thicknesses and widths, including heavy gauge and wide material.
