Product Overview
Metpost Concrete In System 2 designed for 100mm × 100mm square timber posts.
Heavy-duty post support system engineered for setting timber fence posts securely into concrete foundations. Manufactured from galvanised steel for exceptional strength and corrosion resistance, it provides a stable and durable base for fencing, decking, and structural outdoor timber applications.
The System 2 design features a welded steel box section to grip the post firmly above ground level, preventing direct contact with concrete and reducing the risk of rot. The below-ground spike section is embedded directly into a concrete base, ensuring a rigid and permanent fixing even under high lateral load.
The 100mm × 100mm model accommodates standard 4-inch square posts, providing a robust, professional-grade solution for heavy-duty fencing or gate installations.
Features & Benefits
- Strong foundation support: Welded steel construction ensures solid anchoring in concrete for long-term stability.
- Corrosion resistant: Hot-dip galvanised coating protects against rust and environmental exposure.
- Rot prevention: Lifts timber post clear of the ground, reducing moisture absorption and decay.
- Secure grip: Box section holds post firmly in place with twin bolt or clamp fixing.
- Permanent installation: Designed for embedding in concrete foundations for high-strength structural support.
- Size: 100mm × 100mm internal box section suitable for standard 4-inch square timber posts.
Applications
- Fence post installation: Provides a stable, rot-resistant base for timber fencing.
- Gate posts: Ideal for supporting heavy or frequently used gates.
- Decking frameworks: Forms strong, secure supports for timber deck posts or balustrades.
- Outdoor structures: Suitable for pergolas, shelters, and other load-bearing timber constructions.
Installation Guidance
- Preparation: Excavate a hole to required depth and fill partially with wet concrete mix.
- Positioning: Insert the spike section into the concrete and align with post line before setting.
- Levelling: Ensure post holder section remains vertical while concrete sets.
- Post insertion: Once cured, insert the timber post and tighten clamping bolts or screws.
- Final check: Confirm post is square, plumb, and securely fixed before loading.
Compliance & Performance
- Material specification: Heavy-gauge galvanised steel to BS EN 10346.
- Finish: Hot-dip zinc coating for enhanced corrosion protection.
- Post compatibility: Suitable for 100mm × 100mm square timber posts.
- Fixing method: Concrete-in foundation with integral welded steel anchor.
- Durability: Designed for long-term external use in all typical soil and weather conditions.
- Important note: Always ensure correct alignment during setting; allow concrete to cure fully before attaching fencing components.
