Industry Membership

Galvanizers Association of Australia

Steel Source Australia is a member of the Galvanizers Association of Australia (GAA) — the peak industry body for hot dip galvanizing in Australia, established in 1985. Our GAA membership underpins the quality of every galvanised chainwire product we supply: from the zinc coating mass on the wire to the hot dip galvanised posts and fittings.

Chainwire fencing relies entirely on its galvanised coating for corrosion resistance. GAA membership means our team has direct access to the latest technical guidance on coating specifications, inspection standards, and best practice for galvanised steel in Australian conditions — including coastal, industrial, and rural environments where corrosion risk is highest.

AS/NZS 4534

Zinc and zinc/aluminium-alloy coatings on steel wire — the standard governing the galvanised wire used in chainwire mesh fabric.

AS/NZS 4680

Hot-dip galvanised coatings on fabricated ferrous articles — governs posts, rails, and fittings. Minimum 45 µm average coating thickness.

GAA Technical Guidance

GAA publishes design guides, durability calculators, and inspection resources used by engineers and specifiers across Australia.

AS 2423-2002

Chain-link fencing — complete system

The primary Australian Standard governing the complete chain-link (chainwire) fencing system — posts, rails, mesh, fittings, and gates. Specifies minimum requirements for materials, dimensions, construction, and installation. All chainwire products supplied by Steel Source Australia comply with AS 2423-2002.

AS 1725:2010

Chain-link fabric fencing — mesh specification

Specifies mesh aperture tolerances, wire diameter tolerances, selvedge types (knuckled or twisted/barbed), and minimum fence height requirements for various security classifications. Complements AS 2423-2002 for the mesh fabric component.

AS/NZS 4534:2006

Zinc and zinc/aluminium-alloy coatings on steel wire

Governs the zinc coating mass on galvanised and heavy-galvanised chainwire wire. Standard galvanised (G) wire: minimum 30 g/m² zinc. Heavy galvanised (HG) wire: minimum 60 g/m² for extended service life in coastal and agricultural environments.

AS/NZS 4680:2006

Hot-dip galvanised coatings on fabricated ferrous articles

Applies to hot-dip galvanised posts, rails, fittings and gates. Minimum average coating thickness 45 µm on structural sections. Provides cathodic protection — zinc sacrifices itself to protect the underlying steel from corrosion.

Selvedge Types

CodeDescriptionTypical UseNotes
KKKnuckle / KnuckleResidential, schools, pools, sportsBoth top and bottom edges are knuckled (looped back). Safest for areas with pedestrian or child contact. Standard specification.
KBKnuckle / BarbedIndustrial, security perimetersTop edge knuckled; bottom edge twisted to a sharp point. Adds deterrent at the base of the fence. Common on 1800mm+ heights for security applications.

Disclaimer: Nominal wire diameters, mesh apertures and coating masses are subject to permissible manufacturing tolerances per AS 1725:2010, AS 2423-2002 and AS/NZS 4534:2006. Coating mass values are minimum averages — individual test results may vary. Roll lengths vary by mesh size, wire gauge and height — confirm exact roll length at time of enquiry. Specification of chainwire for security-critical applications should be confirmed with a qualified security consultant or structural engineer. Steel Source Australia supplies materials only; installation compliance with AS 2423-2002 and local council requirements is the responsibility of the installing contractor.
