Zinc coating significantly extends the use of the product and reduces costs for its maintenance and replacement. The principle of products protection based on the zinc coating is determined by the difference in the electrochemical potentials of Zn and Fe. The zinc coating in wet environment acts as anode taking care of all harmful processes of oxidation reactions and thus protecting …
AN960 flat washers are used under hex nuts to provide a smooth bearing surface, as shims to obtain the correct grip length for a bolt and nut assembly, and to adjust the position of AN310 and AN320 castle nuts with respect to drilled cotter pin holes in bolts and clevis pins. Available in regular and light thickness. Light Series Washers:
Do not constantly abrade clean your galvanized product and, where possible, avoid abrasive washing of your galvanized product altogether. One of the ways in which galvanizing protects steel from corrosion is by the development of a thin barrier film of insoluble zinc corrosion products (known as a patina) on the outer surface of the galvanized steel through exposure to …

Zinc oxide will contaminate food, even at the temperatures for this application, particularly given the long times involved smoking. It is not necessary to reach the melting or boiling point of a substance in order for it to have a vapor pressure. This is why water will evaporate out of a cup left on the table. Just to make sure I'm not crazy, I checked the MSDS for zinc oxide and have …
