Why is lead added to the. | American Galvanizers Association
The specified lead maximums for the various types of zinc can be found in ASTM B6. Lead does have the beneficial effect of decreasing the surface tension of zinc, which allows it to flow off the steel easier as it is being removed from the kettle. This creates thinner galvanized coatings that have less runs and drips.
