JIS G 3547 Fencing Galvanized Iron Wire(4.0mm-8.0mm)
JIS G 3547 Fencing Galvanized Iron Wire(4.0mm-8.0mm)
Galvanized Wire is made to AS/NZS 4534 "Zinc and zinc/ aluminium-alloy Coatings on Steel Wire"; BS EN 10244. The metallic zinc coatings applied by the galvanizing process are an effective way of combating corrosion in steel. Galvanized wire for general manufacturing purposes is available in a standard galvanized coating or a heavy galvanized coating.
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.

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. 10.00mm | +/-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. 10.68mm | +/-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 |
Please note that the sizes mentioned above are indicative only and do not specify the size range available from my products range.
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.
Tensile Grade | % Carbon | % Phosphorus | % Manganese | % Silicon | % Sulphur |
Soft Medium Hard | 0.05 max 0.15-0.19 0.04-0.07 | 0.03 max 0.03 max 0.03 max | 0.05 max 0.70-0.90 0.40-0.60 | 0.12-0.18 0.14-0.24 0.12-0.22 | 0.03 max 0.03 max 0.03 max |
