Spear Top Fencing, Aluminum Security Fence Panels

FENCE DEPOT is a top fence manufacturer and supplier in China, we can provide quality spear top aluminum fencing panels products for your commercial, industrial, or residential area. Our products are designed to meet the rigorous demands of AS 4421:2019 Level 2 security standards while maintaining architectural integrity.

What distinguishes our fencing systems is the fusion of traditional craftsmanship with modern engineering. The 50mm spear tops, forged from marine-grade aluminum alloy, provide both visual deterrent and functional anti-climb protection. This design ethos allows our panels to serve diverse applications – from government facilities requiring CPNI-compliant barriers to coastal properties demanding salt spray resistance.

Constructed from 6063-T6 aluminum alloy, our panels achieve structural equivalence to mild steel (275MPa yield strength) at 65% reduced weight. The material undergoes a three-stage corrosion protection process: chromium conversion coating, epoxy primer, and UV-stable polyester powder finish. Through robotic welding technology (ISO 3834-2 certified), we ensure joint integrity capable of withstanding 8kN/m lateral impact forces as per AS 1170.1 loading requirements.

Available in standard configurations from 1800mm to 2400mm panel heights, we offer bespoke engineering services for non-standard applications. Our technical team can adjust spear dimensions, optimize post spacing for wind loads, or integrate ground penetration systems compliant with AS 2156 pool fencing regulations.

Advantages of Aluminum Spear Top Fencing:

1. High-strength Aluminum Alloy
   Utilizing 6063-T5 aluminum alloy (typical yield strength ≥160MPa, compliant with AS/NZS 3715) with 3,000-hour salt spray resistance, ideal for coastal applications.
2. tainless Fasteners
   AS 1214-certified 304 stainless steel fasteners maintain structural integrity under 8kN/m horizontal loads (AS 1170.1 compliant).
3. Welded Connections
   Robotic MIG welding (ISO 3834-2 certified) creates seamless connections at all critical stress points, achieving 8kN/m lateral load capacity per AS 4687 requirements.
4. Customizable design
   Tailor dimensions (height: 600-3000mm), picket spacing (50-200mm), and coating colors (RAL/Colorbond® systems) to meet specific site security and aesthetic requirements.
5. Easy installation
   Pre-assembled panels with CNC-punched mounting holes reduce on-site labor by 40%, compatible with both concrete footings (AS 3600) and driven post installations.
6. Competitive pricing
   Direct factory pricing delivers 15-20% cost advantage over local distributors.
7. Extended Service Life
   Typical lifespan: 25+ years in urban environments, 15+ years in coastal zones (AS/NZS 2312.2 compliant).

Spear Top Aluminum Fencing Production Process:

1. Material Checking

All raw aluminum pipes undergo thorough visual inspection to eliminate materials with visible scratches, dents, or surface imperfections. Precise measurements verify outer diameter, wall thickness, and cutting length compliance with technical specifications.

2. Galvanized Pipe Cutting

Specialized equipment cuts aluminum pipes to required lengths using calibrated tools, ensuring clean edges and dimensional accuracy for subsequent processing stages.

3. Punching Holes

Consistently spaced holes are mechanically punched into rails and posts to accommodate fasteners and assembly components, maintaining alignment precision across all panels.

4. Automatic Cutting

Automated machinery shapes picket tops into uniform spear profiles through controlled cutting processes, achieving consistent decorative and functional tip geometries.

5. Welding

Automated machinery shapes picket tops into uniform spear profiles through controlled cutting processes, achieving consistent decorative and functional tip geometries.

6. Cleaning

Post-welding treatments remove residual contaminants through systematic cleaning procedures, preparing surfaces for protective coatings.

7. Surface Pretreatment （Chromizing+Pure Water Cleaning）

A chemical conversion coating process enhances aluminum’s corrosion resistance, followed by thorough rinsing with purified water to ensure optimal coating adhesion.

8. Powder Coating (Topcoat OnlyExpoxy Primer+Topcoat)

Electrostatically applied epoxy primer and polyester topcoat layers are thermally cured to create a durable, weather-resistant finish in standard or custom colors.

9. Quality Control

Final inspection includes cross-sectional coating adhesion tests and micrometer measurements to verify minimum 80μm total coating thickness across all surfaces.
