Precision Leveling

atas-precision-leveling-th.jpgMetal has many characteristics that affect the final look of the manufactured metal sheet or panel. Some characteristics are inherent in the metal such as memory. Some characteristics can be introduced during the production of raw material, during transportation, and while processing the metal with such operations as slitting, cutting and re-coiling. These characteristics can make it challenging to produce consistent, quality sheets and panels. Common inconsistencies seen in coils include:
  • Coil set (Longbow) –  Curvature in the longitudinal direction.
  • Edge wave – Edges are longer than the center.
  • Center buckle (tight edges or oil can) – Center is longer than the edges.
  • Camber – Coil deviation of a side edge from a straight line.
  • Crossbow – Curvature in the transverse direction (along the width of the coil). Similar to coil set.

Equipment used to make corrections:
  • Flattener - Marginally corrects coil set only. No shape improvement. 
  • Straightener (Backed-Up Flattener) - Corrects coil set and crossbow. No shape improvement.
  • Leveler - Corrects all common inconsistencies described in this presentation. Shape improvement of 100-200 I units.

Precision levelers are among the most sophisticated machines used to process metal coil today and are only found in factory environments. Precision leveling allows ATAS to differentiate itself from field roll formers and most manufacturers.

Precision leveling improves quality and consistency of metal sheets and fabricated panels and allows ATAS to declare “If it looks too good to be true... It’s ATAS.”
