Here at Universal Galvanizing, since we place a large emphasis on recycling, we offer our by-products for consideration as well. Those by-products being skims and dross, and zinc/iron sulfate crystals, which can both be recycled and put back into use.
Interested in purchasing these by-products from us? Let us know!
Zinc sulfate and iron sulfate crystals are dissolved solids extracted from our cleaning tanks which can be used to produce fertilizer.
We can also customize different blends to meet your needs.
Skims are the zinc rich oxidation layer that is formed on the top of the kettle after hot-dip galvanization.
This residue layer is skimmed off the top of the kettle and recast into raw zinc, which can be reused in the galvanization process, or made into fertilizers.
Dross is made up of loose particles of steel/iron that react with the molten zinc.
