How Does Wire Drawing Affect Zinc Coating Quality？
Wire drawing is done before galvanizing, so it sets the quality of the steel surface the zinc must bond to; poor drawing with excessive reduction, worn dies, bad lubrication, or leftover scale and lubricant leaves defects and stress in the wire that show up later as uneven, porous, or poorly adhered zinc coatings.

How Is Galvanized Wire Diameter Tolerance Specified?
Galvanized wire diameter tolerance is set by the product standard you order to, such as ASTM A641, EN 10244-2, or a buyer specification, and for drawn wire in the common 1.4 to 5.0 mm range it is normally a bilateral limit of about plus or minus 0.03 to 0.06 mm, verified with a micrometer at several points along the coil.

What Causes Zinc Coating Peeling on Steel Wire?
Zinc coating peels off steel wire most often because the steel surface was not clean enough before dipping, the zinc bath chemistry or temperature was off, or the alloy layer grew too thick and brittle; in short, peeling is almost always a bond or substrate problem rather than a fault in the zinc itself.
