摘要：
The life of galvanized fastener coatings is only slightly reduced by coupling to weathering steel, provided the initial coating is thick enough to endure an Initial period of galvanic attack prior to the development of a protective rust layer on the weathering steel. Typical thicknesses of hot-dip galvanized coatings (3 to 5 mil [76 to 127 mu m]) are adequate. Discoloration on the surface of weathering steel exposed to drainage from galvanized fasteners is superficial, and decreases with time of exposure.
