Chemical Cleaning Process

  • Chemical Cleaning is commonly referred to as “Pickling” in our industry.
  • Our process utilizes Sulfuric Acid for the chemical cleaning (or “descaling”) of steel rods.
  • Our process can clean up to 50 tons of steel per hour.
  • Rods are placed in the acid baths for 30 minutes, double rinsed, and then lime coated.
  • Mid-South Wire has been chemically cleaning steel rods since 1992.  Starting in 2007, our cleaning process has been redesigned, reengineered, and operated by a licensed Chemical Engineer ensuring that Mid-South Wire is an industry leader when it comes to pickling rods
  • We utilize the state-of-the-art Scanacon acid management system for acid reclamation and to maintain optimal “pickling” conditions in our process.
  • Rather than dispose of spent acid, the Scanacon system produces a reusable byproduct (liquid ferrous sulfate) that can be used in other industrial processes.  This prevents us from having to dispose of hazardous wastes.  Furthermore, since we don’t have to treat the spent acid in-house it also reduces our waste treatment chemical consumptions and reduces our landfill footprint.
  • Our chemical cleaning produces the best rod surface quality achievable and is ideal for producing wire for both industrial and plating applications.


Drawing and Re-Drawing

  • Mid-South Wire has a full compliment of wire drawing machines capable of high-speed drawing of carbon steel rod in sizes from .067" to .625"; producing continuous wire coils of 1,000 to 4,000 pounds.
  • We have several types of wire drawing machines; inverted bull-blocks, 2-pass, 3-pass, and other multiple-pass wire drawing machines - over 30 different wire drawing machines for flexibility and quick turn-around. 



  • Mid-South Wire produces hot dip, commercial coat galvanized wire for protection from corrosion.
  • Wire is first passed through a fluidized bed furnace.
  • After passing through the furnace, the wire is cleaned in an acid bath and rinsed prior to going through a flux bath which allows the zinc to adhere to the steel. 
  • The wire is then galvanized by submerging it in molten zinc.
  • As the wire emerges from the zinc, it goes through a wiping station to remove any excess zinc.
  • Chilled water is used to cool the wire. Wire brightness is achieved in this step. 
  • Take-up blocks set the helix and cast in the wire and pattern lay the wire on carriers.
