<p>In a lead-free hot-dip galvanizing method and its processed product, a pure zinc tablet with a 99.995% purity is used and a conventional zinc solution containing lead is changed to a novel hot-dip galvanizing zinc solution for the hot dip galvanizing process. The hot-dip galvanizing zinc solution has a composition of 98% to 99% of zinc, 0.2% to 1.0% of aluminum and less than 1% of a trace element by weight, so that this hot dip galvanizing process with a lead and cadmium free galvanizing condition is achieved.</p> |
