  1. Caustic Cleaning - Similar to hot soap, this alkaline mixture dissolves and removes grease and some paints commonly used in the rolling and fabrication process.
  2. Acid Cleaning (pickling) - At Red River Galvanizing, sulfuric acid is used to remove any rust, mill scale or any other metallic impurity. Once completed, this process leaves the steel "chemically" clean and ready to allow the galvanizing reaction to take place. Three - 7800 imperial gallon acid pickle tanks provides us with adequate pickling capacity to meet our customer's requirements.
  3. Flux - As the final step in steel preparation, fluxing safeguards the steel against premature oxidization which would otherwise allow rust formation and other surface contamination. This contamination, if it were allowed to occur, would greatly impede or even halt the galvanizing reaction.
  4. Galvanizing - Lowering the material into liquid zinc will cause the steel to rise in temperature matching that of the zinc bath. This temperature, sufficient enough to act as a catalyst, initiates the galvanizing reaction. Once complete, the material is slowly withdrawn from the zinc kettle allowing the excess zinc to drain leaving a properly galvanized product. At Red River Galvanizing 4 overhead cranes all with 26 feet of working height and 10 tons lifting capacity provides ample flexibility to produce a superior galvanized product.
  5. Quench - Once galvanized, the material may be quenched in water to reduce its temperature and to allow safe handling. The material may also be immersed in a chromate solution effective in reducing the formation of zinc oxide or what is commonly referred to as white rust or wet storage stain.
  6. Inspection - Once galvanized, all material is inspected using both visual inspection and electromagnetic induction testing to ensure conformance with the specifications CSA G164 - 1981M and ASTM A123.
