Do you know the hot-dip galvanizing process?

The galvanizing process

01 Fabricator removes: welding slag, paint, heavy grease, Avoid silicone/oil based anti-spatter sprays

02 Degrease: removes light oil/grease alkaline or acidic solution

03 Rinse

04 Chemical clean: hydrochloric acid, ambient temperature, removes rust and mill scale

05 Rinse

06 Flux: 30% zinc ammonium chloride solution, 65℃-85℃, aids wetting of steel by molten zinc, sometimes flux blanket

07 Dry: not always necessary, useful for tubular work

08 Galvanize: min. 98.5% zinc, 450℃， typical 5-20 minutes immersion

09 Quench: optional, cool the work, apply post-treatments
