Galvanised Star Pickets

Hot Dipped Galvanised Star Pickets — Buying Guide

Hot dipped galvanised star pickets are the premium choice for Australian fencing projects where longevity and corrosion resistance are paramount. Unlike black bitumen posts, these pickets undergo a hot-dip galvanising process that bonds a thick zinc coating to the steel, providing exceptional protection against rust — even in the harshest coastal and high-humidity conditions found across the Sunshine Coast and South East Queensland.

What Is Hot Dip Galvanising?

Hot dip galvanising involves immersing the steel post in a bath of molten zinc at approximately 450°C. The zinc bonds metallurgically with the steel, creating a coating that is far more durable than paint or standard zinc spray. This process results in a post that resists corrosion for decades, even when partially buried in moist, acidic, or coastal soils — conditions common in many parts of Queensland’s coastal regions.

Why Choose Galvanised Star Pickets?

• Superior corrosion resistance: Zinc coating dramatically outperforms bituminous paint in coastal and high-moisture conditions
• Longer lifespan: Galvanised posts can last 30–50+ years in appropriate conditions vs 10–20 years for black bitumen
• Coastal suitability: Ideal for Sunshine Coast beachside and hinterland properties where salt air accelerates corrosion
• Better resale value: Permanent fencing with galvanised posts adds more durable value to your property
• Low maintenance: Requires minimal upkeep once installed correctly

Available Sizes

• 1350mm: Small animal fencing up to 900mm high
• 1650mm: Standard rural and property boundary fencing —  popular size
• 1800mm: Taller livestock – 1150mm – 1200mm farm fencing – most popular size
• 2100mm+: Taller livestock enclosures up to 1500mm high
• 2400mm+: Security fencing and Taller livestock enclosures up to 1800mm high

When Should I Choose Galvanised Over Black Bitumen?

Opt for hot dipped galvanised star pickets when your fencing is in a coastal location (anywhere within 5km of the ocean on the Sunshine Coast or Moreton Bay regions), when the soil is consistently wet or has high acidity, or when the fencing is intended to be permanent with minimal future maintenance. For drier inland locations or temporary fencing, black bitumen posts are a cost-effective alternative. If in doubt, galvanised is always the safer long-term investment for permanent rural fencing across South East Queensland.

Common Applications

• Coastal property fencing: Essential for Sunshine Coast acreage and beachside properties where salt air is present
• Permanent rural boundary fencing: Long-lasting solution for farms and rural properties across South East Queensland
• Horse and livestock paddocks: Durable posts that won’t corrode prematurely in paddock environments
• High-moisture areas: Creek edges, drainage lines, and wet tropical or subtropical environments
• Government and commercial projects: Where long-term durability and compliance are required

Installation Tips

Galvanised star pickets are installed using the same methods as black bitumen posts — a manual post driver or mechanical post driver can be used to drive them directly into the ground. Space posts 3–4 metres apart for standard wire fencing and 2.5–3 metres for mesh fencing. In rocky or very hard soils (common in some Sunshine Coast hinterland areas), pre-boring a pilot hole will help protect the zinc coating on the post tip from being damaged during driving. Always use appropriate galvanised or stainless steel wire and fittings to avoid galvanic corrosion at contact points.

Frequently Asked Questions

How long do hot dipped galvanised star pickets last?
In standard inland conditions, hot dipped galvanised posts can last 30–50 years or more. In coastal environments like the Sunshine Coast, where salt air is present, lifespan may be reduced but will still significantly exceed that of black bitumen posts. The thickness of the zinc coating is the primary determinant of longevity.

Are galvanised star pickets worth the extra cost?
For permanent fencing installations — particularly in coastal or high-moisture areas — yes, absolutely. The additional upfront cost is easily offset by the extended lifespan and reduced need for post replacement. For temporary fencing or short-term installations, black bitumen posts may offer better value.

Do you deliver galvanised star pickets to Brisbane and the Sunshine Coast?
Yes — we offer Australia-wide delivery with fast dispatch. We supply customers across Brisbane, the Sunshine Coast, the Gold Coast, and all of South East Queensland. Freight is calculated at checkout based on your postcode and order size.

Can I mix galvanised and bitumen star pickets in the same fence?
Yes, you can mix post types within a fence line, though it’s generally better practice to use consistent materials. If budget is a concern, consider using galvanised posts at corners and in the most exposed or moisture-prone sections, with black bitumen posts for the main line runs in drier areas.
