3 1 4 galvanized coil nails

Galvanized iron wire will rust, mainly and the thickness of galvanized layer and the use of the environment, galvanized iron wire is also divided into cold galvanized iron wire and hot galvanized iron wire, in general, hot galvanized iron wire galvanized layer is thicker, rust prevention time is longer, generally can be 7 or 8 years without rust. If the galvanized layer is damaged, or long-term use in a humid environment, it will accelerate the rust time of galvanized iron wire.

Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
