Hot-dip galvanized coatings represent a protection based on passivation of the single zinc layer. It is one of the most commonly used surface treatments of steel. However, pure zinc forms merely (PDF) Characteristics of Hot-dip Zinc Coating MeasurementSebisty effect describes the unusual fact that the thickness of the hot-dip galvanizing coating on the steel containing 0.12%-0.25% silicon decreases with increasing temperature of zinc bath.
1. Bare Spots-Smaller flaws have little effect on the service life of the coating, and can be somewhat self-healing. Some spots may require repair using such methods indicated by ASTM A 780, which includes painting with paints containing zinc, repairing with zinc-based alloys (hot sticking) or by using sprayed zinc (metalizing).

Alliance Steel offers a variety of coated steel sheet and coil products and value-added services to meet customer needs. The steel is coated with zinc to help prevent corrosion. The zinc reacts with oxygen when exposed to the atmosphere, forming a zinc oxide that further reacts with carbon dioxide to form zinc Coated coil and sheet - RyersonThese sheets are cold rolled steel sheets zinc coated by electrolytic deposition and conform to A591. If your application will require outdoor exposure, painting is recommended. The coating has a dull gray matte appearance without the spangles normally present on hot dipped galvanized. The surface has been phosphate treated for immediate Galvanized Angle, Hot Dipped Galvanized Angle - Handy The process is inherently simple and occurs after the steel manufacturing process. It provides a distinct advantage over other corrosion protection methods. It is used where a higher corrosive resistance is required and has a sharper profile on the angle.
