HJ FenceSpear Top Fence vs Palisade Fence: Which Steel Security Fence Should You Choose?
Spear top and palisade are the two steel picket-style fences buyers compare most often — they look similar from a distance, both promise security, and both come galvanized. But they are built differently, cost differently, and suit different jobs. Here is the honest comparison, from a factory that makes steel picket fencing every day.
What is a spear top fence?
A spear top fence is a welded tubular panel: square steel pickets (typically 25 × 25 mm or 19 × 19 mm) are pressed into pointed spear heads and welded between two or three horizontal rails, forming pre-assembled panels usually 2.4 m wide. Panels bolt to posts with brackets. Every tube is hot-dip galvanized inside and out, then powder coated — most commonly in black.
What is a palisade fence?
Palisade is the older British system: individual cold-formed steel pales — in W or D profile with pointed or rounded tops — are bolted or riveted one by one to horizontal angle-iron rails between posts. It arrives on site as bundles of loose pales and rails, and is assembled pale by pale. For decades it was the default industrial security fence across the UK, Commonwealth and rail networks.
Head-to-head comparison
| Factor | Spear Top (Tubular Picket) | Palisade (Steel Pales) |
|---|---|---|
| Construction | Welded pre-assembled panels | Loose pales bolted to rails on site |
| Security | Medium — spear tops deter climbing; welded joints resist dismantling | Medium — pales hard to grip, but bolted fixings can be undone unless anti-tamper |
| Appearance | Clean, modern, architectural — suits street frontages | Utilitarian, industrial |
| Install speed | Fast — 50+ m/day for a two-person crew | Slow — roughly 3× the labor |
| Corrosion protection | Hot-dip galvanized inside + outside tubes, then powder coated | Galvanized; cut edges and bolt holes are weak points |
| Cost | Lower material + much lower labor | Higher material + higher labor |
| Typical heights | 1.2–2.4 m | 1.8–3.6 m |
| Best for | Residential, schools, commercial, factories | Utilities, rail, heritage UK-style specs |
The security reality check
Both fences carry a high-security reputation they don't fully deserve. Palisade pales can be unbolted with hand tools where anti-tamper fixings weren't specified; spear top tubes can be cut with a cordless grinder. Both are excellent deterrents that keep honest people out and delay opportunists. But if your threat model is a determined intruder — a substation, prison or data center — neither is the right product. That is exactly the job 358 anti-climb welded mesh was designed for; we compared it against chain link in detail in our high-security fence guide.
Cost and lifetime
Spear top wins on both price and lifetime cost at typical heights. Less steel per meter, factory welding instead of site assembly, and a duplex galvanized-plus-powder coating that runs 10+ years without maintenance. Palisade's higher steel mass and site labor put it meaningfully above on the invoice, and its bolted joints and cut pale ends are where corrosion starts first. Both are long-lived fences — but spear top usually delivers more fence per dollar for longer.
Which should you choose?
- Residential estates, schools, hotels, commercial frontages — spear top: appearance matters here, and so does fast installation
- Factories and industrial parks — spear top at 1.8–2.4 m covers most needs; add 358 mesh on vulnerable faces
- Utilities, rail and sites with an existing palisade specification — palisade, with anti-tamper fixings specified
- Substations, prisons, data centers, airports — skip both, specify 358 mesh
Frequently asked questions
Which is more secure, spear top or palisade fence?
They sit in the same security tier — both deter casual intruders and neither stops a determined one with tools. Palisade's pointed pales are marginally harder to grip, while spear top's welded tubular construction is harder to deform or dismantle. For genuine high-security perimeters, welded 358 anti-climb mesh outperforms both by a wide margin.
Is palisade fencing more expensive than spear top?
Usually yes at equivalent height, because palisade uses more steel per meter (individual cold-formed pales bolted to rails) and takes longer to install. Spear top's pre-assembled welded panels cut both material and labor cost, which is why it has displaced palisade in most residential and commercial markets.
Can palisade and spear top fences be powder coated in colors?
Both can. Spear top is routinely powder coated over hot-dip galvanizing — RAL 9005 black is standard, any RAL color on request. Palisade is traditionally galvanized only, but powder-coated palisade is available from most manufacturers including color-matched projects.
Do both fence types come with matching gates?
Yes. Spear top systems include swing, sliding and cantilever gates built with identical pickets and coating. Palisade gates exist too but are heavier and typically cost more. HJ fabricates matching gates for every spear top order in the same workshop.
What heights are available for each type?
Spear top commonly runs 1.2–2.4 m (custom heights available). Palisade runs 1.8–3.6 m for security work. For anything above 2.4 m in a genuinely threatened location, compare both against 358 mesh before committing — it usually wins on both security and cost at height.
Which fence is faster to install?
Spear top, decisively. Pre-assembled 2.4 m panels bolt to posts with brackets — a two-person crew can install 50+ meters per day. Palisade arrives as loose pales and rails that are assembled pale by pale on site, typically three times slower.
