Concrete Security Fence Posts

Concrete Security Fence Posts for Heavy Duty Fencing

Our Concrete Security Fence Posts are engineered for maximum strength, stability and long-term performance in demanding outdoor environments. When your fencing requires superior durability—especially in high-wind areas, soil retention projects, or tall fencing installations—these reinforced concrete posts offer a dependable, maintenance-free solution that outperforms standard timber or lightweight alternatives.

Strong, Reinforced and Built for Structural Reliability

Manufactured as wet-cast concrete posts, each unit features a smooth face finish and dense internal structure. They are reinforced with steel rebar rods, significantly increasing their resistance to bending, cracking and ground movement. These posts are specifically designed for installations where structural security is essential, providing the long-lasting support required for heavy duty fencing systems.

Unlike timber posts, these concrete alternatives are fully weather resistant, unaffected by rot, moisture, insects or ground conditions. Once installed, they require zero maintenance and offer decades of dependable service.

No Gravel Board Lug for Flexible Installation

Unlike our standard concrete fence posts, these Concrete Security Fence Posts do not feature a gravel board lug. This purposeful design choice ensures greater flexibility, allowing the post to be installed:

• Deeper into the ground for increased stability
• In custom height fencing layouts
• With non-standard panel or gravel board variations
• In retaining wall or soil-support situations

This makes them ideal for fencing projects that require greater structural freedom or additional load-bearing capabilities.

Larger, Stronger Dimensions Than Standard Concrete Posts

These heavy duty posts are significantly larger and stronger than standard concrete posts. Sizes include:

• Intermediate Posts: 125mm thick x 100mm wide
• Three-Way Corner Posts: 125mm thick x 125mm wide

The increased mass and strength make them ideal for:

• Fences over 6ft in height
• Wind-exposed locations
• Landscaping with sloped ground
• Retaining soil behind fence panels
• Commercial or high-security fencing installations

Wherever extra support is required, these posts deliver superior performance and reassurance.

Ideal for Tough, Long-Lasting Fencing Systems

Thanks to their reinforced construction and durability, Concrete Security Fence Posts are widely used by contractors, landscapers and homeowners seeking a strong and permanent fencing solution. Once installed, they will not twist, warp, split or rot—ensuring your fence remains upright and secure for many years.

Available in Multiple Sizes

While these heavier posts are designed for demanding applications, we also supply standard concrete posts in smaller sizes (sold separately) for general fencing requirements. This ensures customers have the flexibility to choose the right post type for each section of their project.

Choose Concrete Security Fence Posts for unmatched durability, superior strength and long-term stability—ideal for any fencing installation requiring extra security and support.
