For more than 150 years, zinc has been used to protect steel from corrosion, and in particular through hot-dip galvanizing. Zinc is the primary component of the galvanized coating. It is a healthy metal, and is infinitely recyclable, without losing any physical or chemical properties. Natural, essential, and abundant, approximately 30% of the world’s zinc supply comes from recycled sources annually, and 80% of zinc that can be recycled is reclaimed. Zinc, the 27th most abundant element in the Earth’s crust, naturally exists in air, water, and soil.
