Your One-Stop Wire Mesh Fence Supplier | POLYMETAL
Steel picket fence garrison fencing (also called tubular fence panels, ornamental fence panels, or picket-style security panels) is selected when projects need a clean architectural line with real strength for schools, factories, parks, commercial frontage, pools, residential boundaries, and public facilities. Panels are manufactured using high-strength steel pickets and rails (aluminium pickets and rails available on request) and fixed to powder-coated square tubular posts using high-strength brackets for fast, repeatable installation.
The hidden risk is that many steel picket fence garrison fencing panels look similar in photos, but behave very differently once installed. A small downgrade in rail frame size, upright thickness, upright spacing discipline, post option, or anti-tamper fixings can turn a straight perimeter into visible wave-lines, rattles, early coating damage, and costly rejection after installation.
Steel vs Aluminium for Property Enclosures
Steel fence is constructed of steel for maximum longevity and strength, and crafted to look like a traditionally wrought iron fence. While aluminium fence has become popular for property enclosures due to corrosion resistance and weight, steel is the stronger alternative when stiffness, straightness, and impact tolerance matter most across long runs.
What Makes Steel Picket Fence Garrison Fencing “High-Performance” on Site
Steel picket fence garrison fencing succeeds when three things stay controlled: (1) rail stiffness so long runs stay straight, (2) upright discipline so pickets do not “oil-can” and loosen, and (3) post rigidity so gates and corners do not rack the line. When those three are correct, the fence is easy to handle and install, maintains a premium appearance, and stays stable under daily pressure from wind, foot traffic, and vibration.
POLYMETAL supports two common fabrication approaches: rails inserted through uprights for consistent alignment, or face-to-face welding for specific strength targets. Silicon bronze and stainless steel full welding options can be applied where corrosion exposure or long-life performance is required.

Top 10 Shocking Traps Buyers Miss in Steel Picket Fence Garrison Fencing
These are the real reasons buyers lose money on garrison panel orders. The worst cost blowout usually happens when posts are already installed and the line must be rebuilt—especially Trap #7.
Trap #1: The “Looks the Same” Rail Frame Illusion
Two panels can look identical, but a rail frame change from 50×50 to 40×40 can reduce stiffness enough to create wave-lines across long runs. Rail frame choice must match fence height, wind exposure, and bay length.
Trap #2: Upright Thickness Quietly Drops
When upright thickness is downgraded, pickets flex more under impact and vibration, which makes brackets work loose faster and creates visible panel movement. Upright thickness is a stability control point, not a cosmetic detail.
Trap #3: Upright Spacing Is Not Locked
Spacing changes the visual rhythm and the structural behavior. If spacing drifts, panels look mismatched and become harder to align, and the fence line can “walk” as hardware loosens under micro-movement.
Trap #4: Post Option Under-Specified
Many fence failures are post failures. If the post size or wall thickness is too light, the line racks at corners and gates, panels don’t sit flat, and the perimeter looks repaired on day one.
Trap #5: Rail Thickness Not Matched to Height
Rail thickness is the difference between a fence that stays straight and one that develops sag and twist. A tall panel on thin rails can pass initial inspection but drift out of line after repeated loads.
Trap #6: Brackets and Fasteners Treated as “Standard”
High-security appearance is wasted if fixings can be removed with common tools. Anti-tamper proof fasteners and correct bracket selection must be specified as part of the system, not added later.
Trap #7: Post Height Planning Is Ignored (Biggest Rework Trigger)
This is where buyers get hit hardest. If post heights are not specified correctly for embedment, baseplates, and ground variation, installers cut, pack, or re-set posts on site. That creates misaligned bays, uneven top lines, and rework. POLYMETAL recommends post height exceed panel height by 600mm to support proper footing depth and long-run rigidity.
Trap #8: Coating Spec Is Vague
Powder coating performance depends on the full process, not just color. If minimum film thickness, pretreatment, zinc weight, and powder brand are not defined, chipping and early corrosion become disputes.
Trap #9: Packing Discipline Is Missing
Transit damage creates finish defects that become rust starters. Without separation protection, counted bundles, and correct pallet structure, panels rub, corners chip, and site teams mix incompatible components.
Trap #10: Mixed Specs in One Project Without Labels
Mixed rail frames, upright spacing, or post options across one project requires strict labeling. If installers swap panels during deployment, the fence line becomes inconsistent and rework becomes inevitable.
Product Description
POLYMETAL steel picket fence garrison fencing is a tubular picket-style security panel system manufactured from high-strength steel rails and uprights, designed to deliver a clean architectural boundary with real stiffness and repeatable installation. Panels are attached using high-strength steel or aluminium garrison fencing brackets to powder-coated square tubular steel posts, creating a perimeter that is easy to handle and install while maintaining a premium appearance for gardens, schools, factories, pools, residential, industrial, and commercial security projects.
For performance consistency, POLYMETAL offers multiple rail frame sizes (40×40, 45×45, 50×50mm) and upright profiles (16×16, 25×25, 30×30mm) with controlled thickness options. Upright spacing and upright count are selected to match the project’s security feel and wind exposure, while post options (60×60, 65×65, 75×75, 80×80, 100×100mm) are specified with wall thickness discipline so long runs stay straight and gate zones remain stable.

Packing and Container Loading
POLYMETAL packing is designed to protect coating and prevent mix-ups so steel picket fence garrison fencing installs straight and consistent.
- Rubber mat at the bottom of the pallet to avoid pallet damage to the panels.
- Four metal corners to keep the pallet stronger and reduce edge impacts.
- Metal plate under the plastic bandage to reduce band pressure on fence panels.
- Wooden plate at the top of the fence panel to protect panels from being crushed by other pallets.
- Panels separated to prevent rubbing, then wrapped and palletised for forklift handling.
- Posts bundled by size and wall thickness to prevent installation swapping.
- Brackets and fasteners boxed, counted, and labeled by run or height group.
Standard
Steel picket fence garrison fencing performance is controlled by measurable specification: rail frame and thickness aligned to height, upright size and thickness locked, upright spacing and quantity fixed, post option and wall thickness matched to exposure, and coating system defined with minimum film thickness and disciplined pretreatment. If you want a straight, premium fence line, lock Trap #7 (post height = panel height + 600mm) in the purchase order so the foundation and rigidity plan is built in from day one—and if your site is coastal, chemical, or hygiene-sensitive, it helps to understand material-grade differences through our 304L stainless steel guide before finalizing corrosion protection choices.

FAQs steel picket fence garrison fencing
Q1: What is the fastest way to choose the right steel picket fence garrison fencing spec?
A: Start with fence height and exposure level, then select rail frame (40×40 / 45×45 / 50×50), upright size (16×16 / 25×25 / 30×30), upright spacing (100 / 108 / 115), and post option with wall thickness matched to the run.
Q2: Which upright counts are most common?
A: Common options include 16 pcs (115mm spacing), 17 pcs (108mm spacing), and 18 pcs (100mm spacing) depending on security feel and visual density.
Q3: What post sizes are commonly used?
A: Common post options include 60×60, 65×65, 75×75, 80×80, and 100×100mm with wall thickness options 1.6mm, 2.0mm, and 2.5mm.
Q4: What is the most common reason fence lines look wavy after install?
A: Under-specified rails, loose spacing discipline, and posts that are too short or too light for the panel height, especially at corners and gate zones.
Q5: What is the simplest rule to prevent the #7 loss scenario?
A: Keep post height greater than panel height by 600mm so embedment, base stability, and long-run rigidity are built into the layout.
