Galvanised Manufacturing Wire
OneSteel Galvanised Wire is manufactured to comply with AS/NZS 4534 – Zinc and zinc/ aluminium-alloy Coatings on Steel Wire.
The metallic zinc coatings applied by the galvanising process are an effective way of combating corrosion in steel. Galvanised wire for general manufacturing purposes is available in a Standard Galvanised coating (Class W02) and Heavy Galvanised coating (Class W10). Intermediate Galvanised (Class W05) and Ultra Heavy Galvanised (Class W25) & LifeMax® coatings are also available upon enquiry.
Standard Galvanised coatings are typically smoother, however less corrosion resistant than Heavy Galvanised coatings and are often used in general wire working applications. Some typical end uses include cages, bucket handles, coat hangers and baskets.
Heavy Galvanised coatings are used in conditions where atmospheric corrosion is severe. End uses include crop support wires where chemicals are used, pool fencing or chain mesh in coastal areas.
LifeMax® wires are available in a wide range of sizes. LifeMax® is a zinc/aluminium alloy coating that offers improved corrosion performance over conventional galvanised wires. It also has excellent coating ductility and weldability – ideal for woven or welded meshes.

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. Galvanised Manufacturing Wire is produced using soft, medium and hard grade wires.
|Galvanised - Soft Quality||380/550|
|Galvanised - Medium Quality||500/625|
|Galvanised - Hard Quality||625/850|
Note: the sizes mentioned above are indicative only and do not specify the size range available from OneSteel.
OneSteel uses a combination of steel grades and heat treatment processes to manufacture soft, medium and hard tensile grades.
|Tensile Grade||% Carbon||% Phosphorus||% Manganese||% Silicon||% Sulphur|
|Soft||0.05 max||0.03 max||0.05 max||0.12-0.18||0.03 max|
|Medium||0.15-0.19||0.03 max||0.70-0.90||0.14-0.24||0.03 max|
|Hard||0.06-0.10||0.03 max||0.25-0.50||0.12-0.22||0.03 max|
