A 358 fence (3″ x 5″ x 8-gauge mesh) is a high-security fencing system. Here’s a structured guide for installation:
Tools & Materials Needed
- Tools: Post hole digger, level, concrete mixer, wire cutters, tensioning tool (come-along/ratchet), wrench, gloves, safety goggles.
- Materials: Steel posts, 358 mesh panels, concrete mix, galvanized clamps/brackets, barbed wire/razor coils, gravel.
Installation Steps
- Planning & Preparation
- Measure Perimeter: Determine fence layout and mark post locations (8–10 ft apart for stability).
- Check Utilities: Contact local services to mark underground lines.
- Permits: Verify local regulations and obtain permits if required.
- Install Posts
- Dig Holes: Depth = 1/3 post height (e.g., 3 ft for a 9-ft post in a 6-ft fence).
- Set Posts: Place steel posts in holes, fill with concrete, and ensure they’re plumb. Allow 24–48 hours to cure.
- Attach Mesh Panels
- Unroll Mesh: Alroll along posts, starting at a corner. Use gloves to handle sharp edges.
- Tension Mesh: Use a come-along to stretch the mesh taut between end posts.
- Secure to Posts: Fasten mesh with galvanized clamps or brackets at each post. Overlap panels by 2–3 inches and clamp together.
- Reinforce Security Features
- Bottom Edge: Bury mesh 6–12 inches underground or attach to a concrete footing.
- Top Edge: Add barbed wire or razor coils using brackets for anti-climb protection.
- Gates (Optional)
- Install heavy-duty steel gates with reinforced posts and industrial hinges/locks.
- Final Inspection
- Check all clamps, tension, and alignment. Trim excess mesh and file sharp edges.
Safety Tips
- Wear gloves and eye protection.
- Use proper lifting techniques for heavy mesh.
- Ensure posts are fully cured before tensioning.
Common Mistakes to Avoid
- Inadequate Post Depth: Leads to instability in wind or stress.
- Sagging Mesh: Ensure proper tensioning during installation.
- Exposed Sharp Edges: File or cover cut ends to prevent injury.
