① The diameter of galvanized iron wire for pulling should not be less than 4mm, and the diameter of galvanized iron wire for binding should not be less than 2.6mm.

When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.

1. Pickling treatment: the steel wire is soaked in an acidic solution to remove the oil stains and oxidation layers on the surface to ensure the adhesion of the zinc layer.
