Spear Top Fencing, Aluminium Security Fence Panels

FENCE DEPOT is a leading fence manufacturer and supplier based in China. We offer high-quality spear top aluminium fencing panels suitable for commercial, industrial, and residential applications. Our products are designed to meet the stringent requirements of AS 4421:2019 Level 2 security standards while maintaining architectural integrity.

What sets our fencing systems apart is the combination of traditional craftsmanship and modern engineering. The 50mm spear tops, crafted from marine-grade aluminium alloy, provide both a visual deterrent and effective anti-climb protection. This design philosophy allows our panels to be used in a variety of applications, from government facilities requiring CPNI-compliant barriers to coastal properties that need resistance to salt spray.

Constructed from 6063-T6 aluminium alloy, our panels achieve structural equivalence to mild steel (with a yield strength of 275MPa) while being 65% lighter. The material undergoes a three-stage corrosion protection process, which includes chromium conversion coating, epoxy primer, and a UV-stable polyester powder finish. Using robotic welding technology (certified to ISO 3834-2), we ensure joint integrity capable of withstanding lateral impact forces of 8kN/m, in accordance with AS 1170.1 loading requirements.

Our panels are available in standard heights ranging from 1800mm to 2400mm, and we also offer bespoke engineering services for non-standard applications. Our technical team can adjust spear dimensions, optimise post spacing for wind loads, or integrate ground penetration systems that comply with AS 2156 pool fencing regulations.

Advantages of Aluminium Spear Top Fencing:

High-Strength Aluminium Alloy

We utilise 6063-T5 aluminium alloy (with a typical yield strength of ≥160MPa, compliant with AS/NZS 3715) that offers 3,000 hours of salt spray resistance, making it ideal for coastal applications.

Stainless Fasteners

Our fasteners are made from 304 stainless steel and are AS 1214 certified, ensuring they maintain structural integrity under horizontal loads of 8kN/m (in compliance with AS 1170.1).

Welded Connections

We employ robotic MIG welding (certified to ISO 3834-2) to create seamless connections at all critical stress points, achieving a lateral load capacity of 8kN/m in accordance with AS 4687 requirements.

Customisable Design

Our fencing solutions can be tailored to meet specific site security and aesthetic needs, with adjustable dimensions (heights ranging from 600mm to 3000mm), picket spacing (50mm to 200mm), and coating colours (RAL/Colorbond® systems).

Easy Installation

Pre-assembled panels come with CNC-punched mounting holes, reducing on-site labour by 40%. They are compatible with both concrete footings (AS 3600) and driven post installations.

Competitive Pricing

We offer direct factory pricing, providing a cost advantage of 15-20% over local distributors.

Extended Service Life

Our products typically have a lifespan of over 25 years in urban environments and over 15 years in coastal zones, compliant with AS/NZS 2312.2 standards.

Spear Top Aluminium Fencing Production Process:

Material Inspection

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

Aluminium Pipe Cutting

Specialised equipment is used to cut aluminium pipes to the required lengths with calibrated tools, ensuring clean edges and dimensional accuracy for subsequent processing stages.

Punching Holes

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

Spear Forming

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

Welding

Automated welding processes create strong, reliable joints, ensuring the structural integrity of the fencing system.

Whip Blasting

Post-welding treatments involve systematic cleaning procedures to remove residual contaminants, prepare surfaces for protective coatings.

Surface Pretreatment (Chromising + Pure Water Cleaning)

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

Powder Coating (Epoxy Primer + Topcoat)

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

Quality Control

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

Aluminium Spear Top Fencing Application

• Residential Fencing: Aluminium spear top fencing is often used to enclose yards, gardens, and pools, providing security while enhancing the property’s curb appeal.
• Decorative Fencing: The spear top design adds an elegant touch to homes, making it suitable for decorative purposes in front yards or around patios.
