Your One-Stop Wire Mesh Fence Supplier | POLYMETAL
POLYMETAL Diplomat Security Fence is a high-strength tubular picket fence system built for serious perimeter control, clean architectural appearance, and long-term outdoor durability. The system uses vertical steel pickets and rigid horizontal rails to create strong fence panels, supported by square posts engineered to resist impact, vibration, and wind load. To ensure reliable strength and consistent fabrication, many projects specify Q235 steel for key structural components. A Diplomat Security Fence is widely selected for locations where image and security must both be “non-negotiable,” including embassies, government facilities, premium residential estates, campuses, warehouses, and commercial boundaries. When correctly specified, the fence maintains straight alignment, delivers consistent anti-climb performance, and reduces the ongoing cost of repainting and corrosion repairs.
Product Description
POLYMETAL Diplomat Security Fence panels are manufactured using square-tube rail frames and evenly spaced tubular pickets to form a stable, modular panel that installs efficiently and aligns neatly across long runs. Customers can select rail frame sizes such as 40mm×40mm, 45mm×45mm, and 50mm×50mm to match site load and panel span requirements, while picket options typically include 16mm×16mm, 25mm×25mm, and 30mm×30mm to balance security, stiffness, and visual density. For most security-focused projects, upright spacing is designed around 100mm to help discourage footholds and keep the fence line consistent.
For rails and pickets, POLYMETAL offers practical fabrication options based on site needs and budget control. The top and rails can be configured with cut-shut finishing, punched-hole rails, or fully welded construction, allowing you to select the best combination of appearance, speed, and structural integrity. The Diplomat Security Fence system can also be produced in different welding structures to suit production efficiency and long-term strength requirements, ensuring the fence performs as a complete engineered system rather than “panels plus posts.”
Two Welding Systems for Hercules Diplomat Security Fence Panels
POLYMETAL Hercules Diplomat Security Fence panels are available in two commonly used welding structures that affect alignment consistency, load transfer, and production repeatability. One method welds the rails directly to the face of the upright tubes, producing a clean, strong joint and straightforward inspection points. The second method uses punched rails so the upright tubes insert into the rail holes, followed by welding; this structure supports precise spacing control, excellent repeatability, and strong mechanical positioning before welding. Both systems can meet demanding security requirements when paired with correct tube thickness, post sizing, and a proven coating procedure.
Technology Procedure
POLYMETAL Diplomat Security Fence protection typically uses a multi-layer coating process designed to deliver corrosion resistance, coating adhesion, and long-term appearance. Hot-dip galvanizing provides strong protection against rust and corrosion in harsh outdoor environments. Zinc phosphate promotes adhesion between the steel surface and the coating film, improving long-term stability. A zinc-rich epoxy powder coat delivers long-lasting, anti-impact and anti-corrosion performance. A polyester color coat adds extra anti-UV protection, corrosion resistance, and a smoother finish that remains easier to clean and maintain over time.
Key Performance Features
POLYMETAL Diplomat Security Fence can be finished with premium powder coating systems such as AkzoNobel/Interpon to support surface cleanliness, consistent color, and improved long-term appearance. A properly designed multi-layer protection system reduces maintenance pressure across years of service, and robust galvanizing plus quality powder spraying can extend the usable life of the rails and pickets significantly—even in demanding conditions. Precision production helps rails and uprights align with minimal gaps for a cleaner visual result and a stronger “security-grade” impression that matters for high-profile sites.
The Top 13 “Risk” Headlines You Can’t Ignore (Especially #8)
Risk #1: Buying “Security Fence” Without Confirming the Real Anti-Climb Geometry
A Diplomat Security Fence must balance spacing, picket profile, and panel rigidity; if the geometry is wrong, the fence can look strong while still being easy to challenge.
Risk #2: Choosing Rail Frame Size Based Only on Price
A 40×40 rail may work for lighter-duty runs, but longer spans and higher security heights often need 45×45 or 50×50 to reduce flex, vibration, and long-term looseness.
Risk #3: Ignoring Rail Thickness Until You See Denting and Sagging
Rail thickness options such as 1.60mm, 2.00mm, 2.50mm, and 3.00mm directly affect stiffness and impact resistance, especially around access points and high-traffic zones.
Risk #4: Picking Picket Size That Fails Under Real Impact
Selecting 16×16, 25×25, or 30×30 must follow security demand and site risk; undersized pickets may bend under pressure even when the fence looks “premium” at first glance.
Risk #5: Using Upright Thickness That Cannot Hold Straightness Over Time
Upright thickness options like 0.80mm, 1.00mm, 1.20mm, and 2.00mm determine how well the fence survives knocks, vibration, and long-term stress without visible deformation.
Risk #6: Forgetting Upright Quantity Changes the Entire Panel Behavior
Common layouts such as 16 pcs (about 115mm), 17 pcs (about 108mm), and 18 pcs (about 100mm) change stiffness, visual density, and anti-climb performance perception.
Risk #7: Treating Coating as a “Color Choice” Instead of a Protection System
If the process skips proper pretreatment or protective layers, fading, chalking, and early corrosion can appear faster than expected—turning your fence into a repair schedule.
Risk #8: The Post Height Mistake That Forces Rework, Delays, and Security Exposure
If your fence post height is not at least 600mm higher than the fence panel height, stability can fail under real load or installation requirements. This mistake can trigger re-digging, re-setting, re-ordering materials, and losing time on site—while the perimeter remains vulnerable.
Risk #9: Under-Specifying Post Size for Tall Fence Heights
Post options such as 60×60, 65×65, 75×75, 80×80, and 100×100 must match height, wind, corners, and gate loads; the wrong post size can twist, lean, or loosen.
Risk #10: Using Post Wall Thickness That Cannot Hold Anchors and Fasteners
Post wall thickness of 1.6mm, 2.00mm, and 2.50mm changes anchoring strength and durability; thin posts can fail earlier around brackets, base plates, and high-tension sections.
Risk #11: Ignoring Welding Structure Selection for Long Runs
Face-weld rails and punched-insert rails behave differently in assembly consistency and load transfer; choosing incorrectly can create misalignment, weak joints, or difficult installation correction.
Risk #12: Forgetting Corners, Slopes, and Bending Areas Until Installation Day
A Diplomat Security Fence must be specified as a full system with corners, slopes, and transitions; otherwise the site crew will improvise—and the finish will show it.
Risk #13: Not Planning Gate Integration With the Fence System
Sliding gates and swing gates require reinforced posts, correct clearances, and matched panel geometry; poor planning can cause sag, collision, or security gaps at the most critical access points.

Applications
POLYMETAL Diplomat Security Fence is suitable for embassies and diplomatic compounds, government facilities, data centers, premium residential estates, schools and campuses, warehouses, factories, logistics parks, commercial properties, transit boundaries, and high-visibility public areas where a clean appearance must be paired with durable security performance.
The system also works well for slopes, bending areas, and complex perimeters when corners, transitions, and post sizing are planned correctly.
Benefits
A POLYMETAL Diplomat Security Fence supports a high-end architectural look while increasing perimeter control and reducing long-term maintenance. The tubular picket structure provides a strong, straight fence line with consistent spacing, while multiple rail frame and thickness options let you build for real risk level instead of a one-size-fits-all approach.
The multi-layer coating system improves resistance to UV fading, corrosion, and everyday wear, helping the fence remain visually new for longer and reducing the frequency of repainting or repair, protecting both the site and the budget.
Packing
POLYMETAL Diplomat Security Fence is typically packed to prevent coating damage and deformation during shipping. Panels are loaded on metal pallets, wrapped with cardboard plate protection, then wrapped with plastic film and strapped securely. Posts are wrapped with PP bags, placed on pallets, and wrapped with plastic film. Accessories are packed in cartons for organized site handling. Customized packing can be arranged for projects that require specific pallet sizes, labeling, or container loading plans.
Standard
POLYMETAL Diplomat Security Fence production focuses on consistent welding quality, dimensional accuracy, and a controlled corrosion-protection process. Quality control typically covers tube thickness verification, spacing checks, weld inspection, coating thickness control, and packing inspection to reduce site issues. For projects that also require controlled access points during construction or staged handover, temporary fencing gates in Australia can be used alongside the permanent Diplomat Security Fence to manage entry and keep the site organized. Projects requiring enhanced documentation can be supported with production records, material traceability, and batch-based inspection checkpoints aligned to customer acceptance requirements.
FAQs
Q: What makes a Diplomat Security Fence different from a standard tubular picket fence? A Diplomat Security Fence is typically specified with stronger rails, tighter spacing strategy, more robust posts, and a higher-performance coating system so it can handle higher risk environments and long service life expectations.
Q: Which welding system should I choose: face-weld rails or punched-rail insert welding? Face-weld construction offers a clean, direct joint and straightforward inspection, while punched-rail insert welding supports highly repeatable spacing and strong mechanical positioning before welding; both can be selected based on project priorities.
Q: What is the most important sizing rule for posts? Fence post height must be at least 600mm higher than fence panel height to support embedment/anchoring and long-term stability, which is critical for security performance.
Q: Which upright spacing is most common for security-focused projects? 100mm spacing is commonly used because it improves anti-climb behavior and keeps the fence line visually consistent.
Q: Can the system support sliding gates and swing gates? Yes, the fence system can be integrated with both gate types, but gate posts and reinforcement must be selected based on gate weight, frequency of operation, and site wind/impact conditions.
