Pickling

Pickling is a process to “clean” metal surfaces of stains, contaminants, rust, or scale through a chemical reaction that the surface metal undergoes when passed through a pickling line. Depending on the grade of the material being pickled, and the surface condition of the metal, the speed of the strip may be adjusted to allow for more dwell time in the Hydrochloric Acid. Following the pickling process, most sheet steel undergoes an oiling process to protect the newly cleaned metal from oxidation.

We specialize in push-pull pickling, allowing us to process metals from 0.054” - 0.500”. In push-pull pickling, coils are individually fed through the pickling process section to the recoiling mandrel. The advantage of this process is that the bending imposed on the coil is minimal, allowing for the process of higher strength and heavier gauge steels; without the need to weld consecutive coils, a PPPL can process any grade of carbon steel, HSLA or Si steel in any order; and PPPL entry ends are designed to process “out of standard” hot rolled coils that may be collapsed, telescoped, or loosely wound. Our process supplies a stain-free finished product. We have adapted our systems to handle material that other facilities and mills cannot. Our on-site slitter line and newly installed leveling system offer further competitive advantage to customers. We take pride on running our lines 24/7 to meet the demands of our customers. We offer a robust suite of value-added services, including in-line slitting and in-line side trimming.
