Black Bitumen Star Pickets

Black Bitumen Star Pickets — Buying Guide

Black bitumen star pickets are one of Australia’s most widely used fencing posts, valued for their strength, affordability, and ease of installation. The bituminous paint finish provides solid corrosion resistance in standard conditions, making these posts an excellent choice for a wide range of applications across South East Queensland and beyond.

What Are Black Bitumen Star Pickets?

Black bitumen star pickets (also known as Y-posts or steel fence posts) are manufactured from high-tensile steel with a Y-shaped cross-section that provides exceptional rigidity relative to their weight. The bituminous (black) coating acts as a corrosion barrier, protecting the steel from moisture, soil contact, and weathering. These posts are designed to be driven directly into the ground using a manual post driver or mechanical driver — no concrete is required for most applications.

Common Applications

• Rural boundary fencing: Cost-effective for long fence runs on acreage properties and rural blocks across the Sunshine Coast hinterland and Greater Brisbane
• Livestock enclosures: Suitable for cattle, sheep, and goat fencing with appropriate wire strands
• Concrete formwork and boxing: Shorter star pickets (450mm and 600mm) are a popular choice among concretors for securing and bracing formwork and boxing on slabs, paths, and driveways
• Garden landscaping: Ideal for supporting garden borders, retaining mesh, and trellises
• Temporary fencing: Quick to install and remove for construction sites, events, and short-term enclosures
• Erosion control: Used to secure geofabric, coir logs, and erosion mesh on embankments

Available Sizes

• 450mm: Ideal for concretors — perfect for securing and bracing formwork, boxing for slabs, driveways, and pathways where a short, strong stake is needed
• 600mm: Another popular size for concrete formwork and boxing, as well as light garden edging and shallow temporary stakes
• 900mm: Low garden borders and lightweight applications
• 1200mm: Small animal fencing and garden edging
• 1650mm : General use construction and 1150mm high farm fencing
• 1800mm: General use construction and 1150mm / 1200mm high farm fencing
• 2100mm: Tall livestock enclosures usually up to 1500mm
• 2400mm: High-security and tall livestock enclosures usually up to 1800mm

Black Bitumen vs Hot Dipped Galvanised — Which Should I Choose?

Black bitumen star pickets are the most cost-effective option and perform well in standard to semi-rural conditions away from the coast. For properties close to the ocean (such as beachside areas of the Sunshine Coast) or in high-moisture, high-humidity environments, hot dipped galvanised star pickets offer superior long-term corrosion resistance and are worth the additional investment. For inland Brisbane suburbs and drier South East Queensland areas, black bitumen posts are a practical and popular choice.

Installation Tips

Black bitumen star pickets can be driven directly into most soil types using a steel post driver. Space line posts 3–4 metres apart for wire fencing and 2.5–3 metres for mesh fencing. Drive posts to a minimum depth of 300–400mm (deeper in sandy or loose soils). Use larger strainer posts at corners, ends, and gates to anchor your fence line. In hard clay soils common in parts of South East Queensland, a pilot hole may be needed before driving. For formwork applications, 450mm and 600mm posts can be driven in using a hand sledgehammer or post driver and removed cleanly after the concrete sets.

Frequently Asked Questions

How long do black bitumen star pickets last?
With a bituminous coating, black star pickets typically last 10–20 years depending on soil moisture and acidity. In well-drained soils away from the coast, this lifespan is frequently achieved. In wet, acidic, or coastal soils, consider upgrading to galvanised posts for greater longevity.

Can I use short star pickets for concrete formwork?
Yes — 450mm, 600mm and 900mm black bitumen star pickets are widely used by concretors across Queensland for bracing and securing timber formwork when pouring slabs, footpaths, driveways, and other concrete work. They’re strong, cheap, and easy to drive and remove.
