Bitumen black coated star picket: Shocking Top 19 Traps

A Bitumen black coated star picket (also called a Y post, Spar Picket, Star Post, Metal Picket, Steel Fence Post, or Steel Picket) is a steel fence post widely used in Australia, New Zealand, and nearby markets. In cross-section, it forms a three-pointed star (about 10 cm in diameter). One end is pointed to drive into soil more easily, and the other end is flat for hammering. Pre-drilled holes along the post make it fast to tie wire and compatible with Temporary Fence, Barrier Mesh, and rural fencing lines.

POLYMETAL Bitumen Black Coated Star Picket Product Description

POLYMETAL Bitumen black coated star pickets are built for fast, repeatable fencing where corrosion protection and field durability matter. The product line covers bitumen coated steel fence posts, hot dipped galvanizing, and PVC coated options with UV inhibitors, supporting common farm, boundary, and temporary fencing needs across Australia and New Zealand. With an output capacity of 150 ton/day or more, production can support continuous supply for large projects and wholesale distribution. Each post uses a three-point star profile for grip and line stability, includes a pointed driving end for efficient installation, and features pre-drilled holes to speed up wire attachment and integration with Barrier Mesh and Australia Temporary Fence systems—and for buyers comparing protective mesh systems used in adjacent site-safety or enclosure applications, this reference on top 10 stainless steel rope mesh is a useful example of how material selection and structure can change real-world performance.

The Top 19 Buying Traps That Decide Whether You Save Money—or Pay Twice

Why many buyers think they bought “the same star picket,” then lose money later

Most star pickets look similar in photos, but real performance is decided by weight per meter, steel thickness, hole pattern, length selection, coating choice, and how those choices match soil pressure, fence tension, and exposure conditions.

1. Weight per meter is the fastest predictor of line stability under wire tension.
2. Steel thickness determines whether the post resists bending during driving and retensioning.
3. Same size, different strength: 28×28×30mm can still vary drastically by thickness and weight.
4. Wrong length creates shallow embedment, and shallow embedment becomes leaning lines.
5. Hole count controls how cleanly you can set multiple wire heights without improvising.
6. Coating type decides whether corrosion starts early at scratches and impact points.
7. Bitumen coating protects well in harsh environments, but selection must match handling and exposure.
8. Driving conditions punish thin posts first—rocky ground makes “cheap” posts fail fast.
9. Wire attachment method (and hole alignment) affects fence tension consistency over long runs.
10. Market patterns differ: Australia and New Zealand hole layouts can vary by length.
11. Over-buying length can waste cost if it slows crews and increases handling damage.

Trap #12: The “lightweight post” choice that triggers leaning, re-driving, and repeat labor loss

If you choose a lower weight-per-meter post (for example 1.58kg/m) for a line that needs high tension or faces livestock pressure, the post can lean, twist, and lose alignment faster—forcing re-driving, extra strainer work, and repeated tightening. That “small” weight choice becomes the most expensive mistake because it multiplies labor and repair costs every time the fence is retensioned or repaired—and if you’re comparing perimeter solutions beyond star pickets, this Diplomat fencing reference shows how heavier-duty security fencing systems are typically positioned for higher-pressure sites.

13. Bitumen coating thickness matters—thin coverage increases early corrosion at wear points.
14. Transport damage often comes from poor packing, not “bad steel.”
15. Hole spacing consistency prevents uneven wire heights that weaken the fence line.
16. Project standardization reduces onsite confusion and mixed-strength sections.
17. High-output supply protects you from schedule slips when the job needs fast replenishment.
18. Choosing the right series is cheaper than fixing a fence that fails after install.
19. The smartest buy is the one that avoids rework within a season.

Applications Bitumen black coated star picket

• Rural farm fencing lines for livestock boundaries and paddock subdivision
• Temporary fencing support for Barrier Mesh and site separation
• Orchard, vineyard, and plantation posts where fast driving and repeat spacing are needed
• Roadside, reserve, and general boundary marking in Australia & New Zealand
• Security and exclusion zones where wire tension and post stability must hold over time

Benefits Bitumen black coated star picket

• Bitumen black coating improves corrosion resistance and protects the steel surface in harsh outdoor conditions
• Three-point star profile grips soil well to reduce twisting and line drift
• Pointed end installs faster and reduces effort in firm ground
• Flat hammer end supports repeated driving without deforming the top
• Pre-drilled holes speed up wire attachment and improve consistent fence tension
• Multiple weight-per-meter options let you match strength to livestock pressure and terrain

Standards Bitumen black coated star picket

• Material: carbon steel star-profile fence posts for rural and temporary fencing use
• Coating options: bitumen coated; hot dipped galvanizing; PVC coated with UV inhibitors
• Manufacturing control: consistent section size (28×28×30mm) with selectable thickness (2.3–3.0mm) and weight classes (1.58–2.04kg/m)
• Hole pattern control: pre-drilled holes along the post length (Australia & New Zealand patterns available)

Packing Bitumen black coated star picket

• Bundled in tight steel-strapped packs by length and weight class to prevent mixing on site
• Wrapped with waterproof film to reduce moisture contact and coating abrasion during transport
• End protection applied to reduce point damage and prevent tearing of wrapping
• Palletized or container-loaded in layered stacks with spacers to reduce rubbing and impact marks
• Clear outer labels showing length, weight-per-meter, quantity, and batch for fast receiving
