Tubular Steel Security Fence – 9 Shocking Facts Read More

If you are planning a perimeter, pool or boundary upgrade, the tubular steel security fence from POLYMETAL – or complementary systems such as crimped spear garrison fencing or garrison fencing panels – may look like a simple choice. But there are several hidden angles that can quietly drain your budget, weaken security and damage your project reputation if you pick the wrong specification or supplier.

The photos and drawing above show a typical POLYMETAL tubular steel security fence panel: one engineering drawing with all dimensions and one real product photo installed in a landscaped area. Together they give you a clear snapshot of what you are really buying.

Below you will find 9 critical facts about this security fence design. Ignore the last crisis warning and you may end up paying twice—once for the fence, and once to fix the damage.

Product Description – POLYMETAL Tubular Steel Security Fence

• Brand: POLYMETAL engineered fence system for residential, commercial and industrial security projects
• Product Type: Tubular steel security fence, flat-top or spear-top architectural style
• Typical Panel Size: Approx. 2400–2450mm wide × 1200–2400mm high for efficient bay layout
• Vertical Uprights (Pickets): Square steel tubes (16×16mm, 25×25mm or 30×30mm) passing through or welded to horizontal rails for a strong, rigid connection
• Horizontal Rails (Frames): Square steel tubes (40×40mm, 45×45mm or 50×50mm) positioned to optimise strength and prevent sagging
• Rail Positioning: Rails set to suit fence height, with calculated clearances at top and bottom for security and aesthetics
• Upright Spacing: Approx. 100mm centre-to-centre to deter climbing and prevent intrusion while allowing visibility
• Surface Finish: Pre-galvanised or hot-dip galvanised steel plus black or custom-colour polyester powder coating for long-term corrosion resistance
• Security Profile: Clean tubular profile with minimal footholds, suitable for high-security boundaries and controlled-access zones
• Function: Provides a strong physical barrier, clear perimeter line and visual deterrent while maintaining airflow and sightlines
• Compatibility: Designed to work with matched posts (60×60, 65×65, 75×75, 80×80 and 100×100mm), gates and accessories for complete systems
• Typical Applications: Warehouses, logistics yards, substations, schools, car parks, industrial estates, high-end residential boundaries and public infrastructure
• Design Purpose: Combine robust security, professional appearance and long service life with a repeatable, easy-to-install tubular fence format

Engineering Snapshot – Tubular Steel Security Fence

The technical drawing above gives an accurate outline of the POLYMETAL tubular steel security fence panel:

• Fence panel height options from 1200mm up to 2400mm
• Fence panel widths around 2400–3000mm for efficient post spacing
• Rails in 40×40mm, 45×45mm or 50×50mm square tubes
• Uprights in 16×16mm, 25×25mm or 30×30mm square tubes at 100mm spacing

9 Critical Facts About the Tubular Steel Security Fence You Must Not Ignore

Fact 1 – Dimension Data That Decide Your Real Security Level

The height of a tubular steel security fence is not just a line on paper. A 1800–2400mm high panel with 100mm upright spacing:

• Makes climbing extremely difficult due to limited footholds
• Keeps intruders in full view of CCTV and security patrols

Choose the wrong height or spacing and you create a gap in your security strategy that intruders can exploit.

Risk 2 – Structural Aspect That Separates Light Barriers from True Security

The combination of rail frame size (40×40, 45×45 or 50×50mm) and upright size (16×16, 25×25 or 30×30mm) defines the structural aspect of the fence:

• Too light and panels bend, rattle or deform under impact or wind
• Overbuilt in the wrong way and you pay extra for steel without gaining real performance

POLYMETAL balances these elements so your tubular steel security fence remains rigid along long runs without unnecessary weight.

Trap 3 – Coating Oversight That Turns Your Fence into a Rust Problem

Many buyers compare only height and price and forget the surface treatment. That oversight is a classic trap:

• Poor galvanising or thin powder coating becomes a rust starting point
• Corrosion spreads from cut edges and welds, attacking the inside of tubular sections
• Your fence looks old and unsafe long before the end of its design life

Specifying proper galvanising plus high-build powder coating is a non-negotiable rule if you want a security fence, not a future maintenance crisis.

Warning 4 – Post Selection Mistake That Quietly Destroys Stability

The strongest panel fails if the posts are wrong. Under-sized or short posts introduce a hidden warning sign:

• Posts begin to lean, especially on soft or backfilled ground
• Panels loosen at fixing points and start to rattle or move
• Repairs require breaking out concrete and re-setting posts at high cost

Matching fence height to post size—60×60, 65×65, 75×75, 80×80 or 100×100mm, with correct embedment depth—is a critical lesson for long-term stability.

Cost 5 – Installation Pitfall That Eats Your Budget from the Inside

Tubular steel security fence systems with the wrong panel width or rail configuration can create a serious cost pitfall:

• Extra posts increase concrete, labour and hardware costs
• Non-standard panels need cutting and re-welding on site
• Time lost on awkward alignment delays other trades and project milestones

Using standardised POLYMETAL layouts with 2400–3000mm panel widths and consistent rail locations gives you a clear payoff in lower installation time and labour.

Benefit 6 – Security Advantage That Boosts Deterrence and Image

A tubular steel security fence can deliver more than a physical barrier. When properly specified, it offers a clear benefit:

• A clean, professional perimeter that sends a strong security signal
• Visibility that allows guards and cameras to see threats approaching
• A neat, modern profile that enhances rather than harms your site’s image

This advantage improves both deterrence and perceived quality of the facility.

Checklist 7 – Compliance Guide You Must Run Before Ordering

Before placing any order for a tubular steel security fence, run this quick checklist:

• Does fence height comply with local security, pool or boundary regulations?
• Is 100mm upright spacing appropriate for anti-climb and safety requirements?
• Are gate frames, hinges and locks matched to the same security level as the fence?
• Are posts, rails and uprights all correctly galvanised and powder coated?

Treat this as your personal guide. Skipping it can lead straight to inspection failures, retrofits and schedule damage.

Myth 8 – Illusion That “Any Tubular Fence Is the Same”

There is a dangerous myth that “tubular steel security fence systems are all identical”. That illusion hides real differences in:

• Upright thickness and steel grade
• Weld quality and internal corrosion protection
• Fixing hardware, bracket design and anti-tamper details

Believing this misbelief pushes you to choose the lowest upfront price instead of the best long-term security and reliability.

Crisis 9 – Supplier Choice That Can Turn Protection into Loss

Here is the final crisis point most buyers only understand after something goes wrong:

If you choose the wrong supplier for your tubular steel security fence, the real cost is not the first invoice—it is the loss when the system:

• Fails under impact or extreme weather
• Shows coating failures and rust within a few seasons
• Does not match the drawings or promised specifications
• Needs partial or full replacement while the site is already operational

Working with POLYMETAL, with documented data, engineering drawings, real photos and consistent manufacturing, gives you a crucial edge, especially when you are comparing solutions with china hercules fencing panels. Ignore this last fact and your security fence can flip from asset to liability overnight.
