Why hot-dip galvanized reinforcing steel works
- No corrosion creeping under the zinc coating;
- No holidays in the zinc coating; the hot-dip galvanizing process ensures complete coating coverage;
- Zinc corrosion products are less dense than black steel corrosion products and migrate away from the bar into the voids of the concrete and thus no cracking or spalling forces are exerted;
- Zinc corrosion products passivate the rebar, elevating the corrosion threshold to a range between five and 10 times that of bare rebar;
- Zinc corrosion products block the progress of chloride ions to the rebar;
