How strong is galvanized iron wire?

The strength of galvanized iron wire can vary depending on factors such as its diameter, the specific grade of iron or steel used, and the galvanization process. The strength of galvanized low carbon steel wire is often measured in terms of tensile strength, which is the maximum amount of tensile (pulling) stress that the wire can withstand without breaking.  

Galvanized iron wire typically has a tensile strength ranging from 350 MPa to 550 MPa, depending on its specific grade and thickness. 


4. Manufacturing Process of Galvanized Iron Binding Wire

--Wire Drawing:

The process begins with wire drawing, where low carbon steel rods are drawn through a series of dies to reduce their diameter. This results in a long, continuous wire that serves as the base material for galvanized binding wire.


--Pickling:

The drawn wire is then subjected to a pickling process. Pickling involves immersing the wire in an acidic solution, usually hydrochloric acid, to remove any rust, scale, or impurities from the surface of the wire. This step ensures a clean and smooth surface for the subsequent galvanization process.

--Zinc Coating (Galvanization):

The cleaned wire is immersed in a bath of molten zinc or passed through a galvanizing chamber where zinc is applied to its surface. There are two main methods of galvanization:
Hot-Dip Galvanization: The wire is fully immersed in molten zinc, forming a thick and uniform coating.
Electrogalvanization: Zinc is electroplated onto the wire's surface, providing a thinner but still effective coating.

The Zinc Thickness about GI iron wire depends on the manufacyuring process.Hot-dipped galvanized iron wire zinc thickness is 50-60g/m2.Electro-galvanized iron wire zinc thickness is 15-20g/m2.

--Cooling and Drying:

After galvanization, the wire is cooled to solidify the zinc coating. This may involve passing the wire through a cooling chamber. Subsequently, the wire is dried to remove excess moisture.

--Spooling or Coiling:

The galvanized wire is then spooled or coiled for packaging. It may be wound onto spools, formed into coils, or cut into specific lengths depending on the intended packaging and distribution.
