The ICC Ceiling rods (ICCMSLCMRK) and nuts from the kit are zinc plated. Zinc plating is normally 0.2 mils thick while galvanizing can be up to 1.0 mils thick. With over 5 times the protection it makes galvanizing ideal for outdoor use. All true galvanizing is hot dip galvanizing. Parts to be galvanized are submerged in molten, liquid zinc; hence the name “hot dip”. After 20 years outdoors a galvanized product will not show signs of rust. The galvanized product will develop a white protective coating (zinc oxide) that adds to its protective properties. Zinc plating has found wide acceptance as a surface finish for consumer, industrial, and commercial products. The relatively low cost, protective nature and attractive appearance of zinc plating make it a popular coating for nuts, bolts, washers, metal stampings, automotive components and fabricated parts for industrial applications.
