Palisade Fencing
Complete palisade fencing supply — flat top, spear top and triple point pales, line and end posts, horizontal rails, pre-assembled panels, security fixings and single and double leaf gates. Galvanised and powder coated finishes. Suitable for commercial, industrial, government and high-security perimeter applications.
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 since 1985. Palisade fencing is manufactured from hot dip galvanised steel to AS/NZS 4680, and GAA membership ensures our team can advise on the correct coating specification, expected service life, and inspection requirements for your application.
AS/NZS 4680
Hot-dip galvanised coatings on fabricated ferrous articles. Governs the galvanised coating on palisade pales, rails, and posts. Minimum average coating thickness 45 µm (local minimum 35 µm).
GAA Durability Guidance
GAA technical publications and the online durability estimator help engineers and specifiers predict coating life in coastal, industrial, and rural environments.

AS/NZS 4100:2020
Steel Structures
Governs the design of steel structural members used in palisade fence posts and rails. Palisade posts are typically 65×65×6 RHS or 100×50×5 RHS to AS/NZS 4100. Minimum yield strength 350 MPa (Grade C350L0) for cold-formed hollow sections.
AS/NZS 4680:2006
Hot-dip galvanised (zinc) coatings on fabricated ferrous articles
All galvanised palisade components — pales, posts, rails and fixings — are hot-dip galvanised to AS/NZS 4680. Minimum average coating thickness 45 µm on structural sections ≥6mm. Provides cathodic protection and a service life of 25–40 years in inland environments.
AS/NZS 4534:2006
Zinc and zinc/aluminium-alloy coatings on steel wire
Applies to galvanised wire used in palisade fixings and security topping. Minimum zinc coating mass 30 g/m² for standard galvanised; 60 g/m² for heavy galvanised wire used in coastal or high-exposure environments.
AS/NZS 4506:2005
Thermosetting powder coatings
Powder-coated palisade components are finished to AS/NZS 4506. Minimum dry film thickness 60 µm for exterior applications. Standard colour is Black (Dulux Powder Coat equivalent); custom RAL colours available on request for minimum order quantities.
Pale Profile Selection Guide
| Profile | Security Level | Typical Use | Notes |
|---|---|---|---|
| Flat Top (FT) | Low–Medium | Residential, decorative commercial | Aesthetic appeal; no anti-climb deterrence; suits heritage and streetscape applications |
| Spear Top (ST) | Medium–High | Commercial, industrial perimeters | Single point deters climbing; most common commercial specification |
| Triple Point (TP) | High | Critical infrastructure, utilities, corrections | Three-pronged top; maximum anti-climb deterrence; typically 1800mm+ height |
| Bow Top (BT) | Low | Parks, schools, public spaces | Curved top with no sharp points; child-safe; complies with playground safety guidelines |

Disclaimer: Nominal pale dimensions (65×16mm flat bar), post sizes and coating thicknesses are subject to permissible manufacturing tolerances per the applicable Australian Standards. Pale spacing, post embedment depth and rail sizing must be designed by a qualified structural engineer for security-critical applications. Steel Source Australia supplies materials only; installation compliance with AS/NZS 4100:2020 and local council requirements is the responsibility of the installing contractor.
