Red River Galvanizing Inc. strives be an environmentally sustainable hot-dip galvanizing company. Using hot-dip galvanized steel ensures fewer natural resources are consumed, fewer emissions are put out, and less money is spent over the life of a project. Galvanizing is a maintenance-free corrosion protection method, so there are no additional materials or consumption required to re-coat galvanized steel. We are a 100% lead-free plant. We have a state-of-the-art acid recovery system in place, in order to reuse the acid in the pickling process, and to make use of the waste iron left from this process. Any zinc that may splash out of the kettle is swept up and reused.

Combine galvanized steel’s low environmental impact with its low life-cycle cost, and it is clear that hot-dip galvanized steel is a sustainable construction material.


We are a lead-free plant! Lead-free means that no lead is used in the galvanizing process, and that we use a lead-free zinc bath.


For more than 150 years, zinc has been used to protect steel from corrosion, and in particular through hot-dip galvanizing. Zinc is the primary component of the galvanized coating. It is a healthy metal, and is infinitely recyclable, without losing any physical or chemical properties. Natural, essential, and abundant, approximately 30% of the world’s zinc supply comes from recycled sources annually, and 80% of zinc that can be recycled is reclaimed. Zinc, the 27th most abundant element in the Earth’s crust, naturally exists in air, water, and soil.


We have a new state-of-the-art acid recovery system from Phoenix Systems. This system removes iron from spent pickling liquor effectively, resulting in a more reactive acid which pickles the steel more thoroughly, and at a faster rate. The acid recovery system allows for the reuse of acid without sacrificing efficiency. The solids produced during the acid recovery process can be used in fertilizer production, and is not discarded. There is no additional waste created using this system.

Sulfuric acid recovery system


  • More reactive acid pickles steel more completely and quickly.
  • Efficient iron removal increases throughput and reduces product defect.
  • More effective iron precipitation improves rinse and flux tank chemistry, thereby resulting in significantly less ash, skims, and dross.
  • The tank heating system is optimized as low iron levels reduce the formation of ferrous sulfate monohydrate crystals on heat exchanger surfaces.
  • Acid disposal is eliminated and co-products are sold as valuable industrial chemicals.


  • The acid is first piped in from the acid tank to the recovery tank. The acid is cooled before it reaches the tank.
  • The acid is then pumped into the tank, where turbines churn the acid, sifting the solid material out.
  • The solid material gets pumped into a separate repository, while the clean acid gets pumped out of the tank to be reheated and returned to the kettle.
  • The solid material is then up-cycled in other forms, such as being used in fertilizer.
