Garrison Security Tubular Fence: Dangerous Top 18 Traps

Garrison Security Tubular Fence is chosen when a project needs a clean architectural line, controlled access, and a stronger security presence than chain link fence or weld wire fence.
But the real danger is not the product—it’s the wrong specification. One missing thickness, one mixed spacing, or one under-built post schedule can turn a premium perimeter into a “repaired-looking” line overnight.
If you’re comparing fence types, you’ll often see people default to chain link fence and weld wire fence for cost reasons, yet garrison tubular systems are selected when straightness, appearance, and gate performance must stay consistent for years.

Product Description (POLYMETAL)

POLYMETAL Garrison Security Tubular Fence is a welded panel system built for commercial and industrial perimeters where straight lines, repeatable bay alignment, and reliable gate performance are required.
The system uses square-tube rails (40×40mm, 45×45mm, or 50×50mm) combined with welded tubular uprights (16×16mm, 25×25mm, or 30×30mm) to deliver a consistent visual rhythm and strong “stay out” message.
Rail thickness options (1.60mm, 2.00mm, 2.50mm, 3.00mm) and upright thickness options (0.80mm, 1.00mm, 1.20mm, 2.00mm) allow the same garrison style to scale from standard boundary control to heavier-duty security zones.
Posts are specified to exceed the panel height by 600mm to support embedment and stability, helping the fence stay vertical under daily load.

Why This Fence Wins on Commercial Sites

Commercial perimeters are judged instantly. A straight line looks controlled. A leaning line looks unmanaged. That’s why a garrison tubular system must be specified as a schedule, not as a name.
When every bay matches, installers move faster, gates align cleanly, and the finished perimeter looks premium from day one—without the visible patchwork that triggers complaints, site rework, and security doubts.

Applications Garrison Security Tubular Fence

Garrison Security Tubular Fence is widely used for industrial and commercial sites, boundary fencing, schools and parks, public facilities, factories, villas, workshops, warehouses, logistics yards, commercial car parks, storage compounds, and construction zones where a clean and controlled perimeter is required.

Benefits

This system delivers high security with minimal wind resistance, lower maintenance cost through robust galvanized and powder coated finishes, anti-tamper fastener compatibility, and a contemporary design that stays visually clean and is less attractive to graffiti vandalism.
The biggest real-world benefit is repeatability: matching bays install faster, gates align more reliably, and the finished perimeter looks premium instead of patched.

Packing Garrison Security Tubular Fence

POLYMETAL packs panels stacked flat with separation protection, then wraps and palletises for forklift handling to protect straightness and coating.
Posts are bundled by size and wall thickness and labelled by height group, while brackets, screws, and accessories are packed in cartons to prevent missing parts that delay installation and force unsafe on-site substitutions.

Standards & Documentation

Typical project documentation specifies rail frame size, rail thickness, upright size, upright thickness, upright count/spacing, post size/wall thickness, post height (panel height + 600mm), welding method, and finish system.Common finish references include galvanized tubing to AS/NZS 1163 and powder coating to AS/NZS 4506-1998 with minimum 80 micron thickness and INTERPON powder options in black or the full RAL colour chart.

Top 18 “Don’t Get Burned” Items for Garrison Security Tubular Fence (Especially #15)

Trap #1: Ordering by name only and leaving rail frame size undefined

40×40, 45×45, and 50×50 are different strength classes. If you don’t lock it, you can receive mixed rigidity and a mixed perimeter line.

Risk #2: Under-building posts for the fence height

Light posts drift first, then seams look uneven, and the line reads crooked from the street.

Warning #3: Missing rail thickness in the purchase order

1.60mm and 3.00mm rails behave completely differently under gate load and corner pressure.

Detail #4: Mixing 2400mm and 2450mm widths without a bay plan

One wrong width forces patch bays, destroys alignment, and makes the perimeter look repaired.

Fact #5: Upright thickness decides rigidity and “presence”

0.80mm uprights may look fine in photos, but they can feel weak in pressure zones; thicker uprights hold the line.

Point #6: Upright count controls spacing and finished rhythm

16 pcs (115mm), 17 pcs (108mm), and 18 pcs (100mm) must stay consistent across the entire run.

Note #7: Ignoring post height as panel height + 600mm

Short posts force shallow embedment and shallow embedment turns into early movement, leaning, and rework.

Tip #8: Treat corners as a different specification class

Corners take load first. Upgrade posts and rail thickness at corners before you regret it.

Hint #9: Gate-adjacent bays need upgrades, not standard middle-bay specs

The first two bays beside every gate carry daily load. If they’re under-built, they move first.

Idea #10: Choosing “black” without specifying coating thickness

Colour is not performance. Minimum 80 microns helps protect the finish in commercial environments.

Aspect #11: Not controlling wind and knock forces in open areas

Even minimal wind resistance does not mean “no movement.” Post schedule and embedment decide long-run stability.

Feature #12: Anti-tamper fasteners only work when bracket schedules are correct

Wrong bracket counts or mismatched screws create looseness, and looseness becomes gaps and noise.

Trend #13: Public-facing sites punish messy lines

A straight garrison fence communicates control; a wavering line looks unmanaged and invites complaints.

Problem #14: Transport damage happens during unloading

Bent corners and scratched coatings appear instantly after install, making a “new” fence look old.

Loss #15: The expensive failure—perfect middle bays, but weak corners and gate returns

This is the expensive failure: the middle bays look perfect, but corners and the first two bays beside every gate are under-built.
Those areas take the daily load, they move first, and the whole perimeter looks “repaired.”
The rework cost is brutal because it is visible and disruptive.

Damage #16: Accepting mixed post walls in one line

Mixed stiffness creates mixed movement, and the perimeter looks inconsistent over time.

Hazard #17: Letting site objects become ladders

Pallets, bins, and stacked materials near the fence turn a strong perimeter into a climb-assisted one.

Boost #18: A complete spec schedule is the fastest path to a premium perimeter

Lock rails, thickness, uprights, spacing, posts, and heights. The fence installs faster and stays straighter.
