Hot-dip coated steel articles having a coating containing about 55% aluminum, 43% zinc, 2% silicon, are known to exhibit an optimum combination of general corrosion resistance, more durable than zinc coatings; while providing more galvanic protection to cut edges and areas of mechanical damage than hot-dip aluminum coatings. It has now been found that coatings containing 12 to 24% zinc Zinc coating (Z) - Hot-dip galvanized steel - SSAB
Zinc coating (Z) produced on both sides by hot-dip galvanizing extends the service life of the end product by protecting the steel from corrosion. The continuous hot-dip galvanizing process offers a wide protection range from Z100 to Z600 in addition to a tight bond between the coating and the steel. Zinc-Coated Ductile Iron Pipe WSSC WaterFeb 25, 2021 · Its ductile iron pipe sprayed with a zinc coating. The zinc serves as corrosion control. The zinc is consumed in place of the iron.
