Hot-Dipped Galvanized Iron Wire

Standard galvanized coatings are smoother, however less corrosion resistant than heavy galvanized coatings and are often used in normal wire working applications. Some typical end users include cages, bucket handles, coat hangers and baskets.
Heavy galvanized coatings are used in conditions where atmospheric corrosion is severe. End users include crop support wires where chemicals are used, pool fencing or chain mesh in coastal areas.

Galvanised Wire Working Specifications
Given that galvanized wire is classified according to the amount of zinc coating, the following table outlines the difference between standard, heavy galvanized and extra-high galvanized wire.

Diameter Properties
Standard Galvanized Wire is manufactured to comply with the following diameter tolerances:

Nominal Wire Diameter	Tolerance (mm)
over 0.80mm up to and incl. 1.60mm                over 1.60mm up to and incl. 2.50mm                over 2.50mm up to and incl. 4.00mm                over 4.00mm up to and incl. 6.00mm                over 6.00mm up to and incl. 8.00mm	+/-0.03                +/-0.03                +/-0.03                +/-0.04                +/-0.04

Heavy Galvanized Wire is manufactured to comply with the following diameter tolerances:

Nominal Wire Diameter	Tolerance (mm)
over 0.80mm up to and incl. 1.60mm                over 1.60mm up to and incl. 2.50mm                over 2.50mm up to and incl. 4.00mm                over 4.00mm up to and incl. 5.00mm                over 5.00mm up to and incl. 6.00mm                over 6.00mm up to and incl. 8.00mm	+/-0.04                +/-0.04                +/-0.04                +/-0.05                +/-0.05                +/-0.05

Tensile Strength (Mpa)
The tensile strength is defined as the maximum load achieved in the tensile test, divided by the cross-sectional area of the wire test piece. Galvanized Wire is produced using soft, medium and hard grade wires. The following table specifies the tensile range according to the grade:

Grade	Tensile Strength (Mpa)
Galvanised - Soft Quality                Galvanised - Medium Quality                Galvanised - Hard Quality	380/550                500/625                625/850

Steel Chemistry
 A combination of steel grades is used and heat treatment processes to manufacture soft, medium and hard tensile grades. The table below is indicative only of steel chemistries used.
