The ULAMEX Fencing Mesh Accessories range provides every hardware component needed to assemble a complete perimeter fence from fence posts, mesh panels, and barbed wire. Manufactured from galvanised steel and UV-stabilised plastic, these accessories are sized to fit the two standard post diameters in the ULAMEX fencing programme — 42.4 mm and 48.3 mm — ensuring a precise, secure fit without modification or adaptation on site.

| Anti-tamper bolt | Galvanised steel | M8 / M10 | Security bolt requiring special tool to remove |
Installation
Fencing accessories are installed sequentially as the fence is assembled. The typical installation sequence for a solar farm perimeter fence is as follows:
- Post caps (dome or flat) — press-fit or bolt onto the top of each post before erecting the post, preventing debris from entering the tube during installation. Alternatively, fit after erection but before attaching mesh panels.
- Mesh clamps or saddle clips — attach the fence mesh panel to each post at three points: top, middle, and bottom of the panel. For the U-bolt mesh clamp, pass the U-bolt around the post, place the mesh panel against the flat bar, and tighten the nuts to 8–12 Nm. For saddle clips, wrap the clip around the post from behind the mesh and secure with the integral bolt. Use anti-tamper bolts on the external face in high-security installations to prevent unauthorised removal.
- Barbed wire arms — bolt the Y-arm or cranked arm to the top of each post after mesh installation. The Y-arm accommodates three rows of barbed wire on its two angled branches; the cranked arm supports a single-direction overhang with two to three wire rows. Tighten the clamp bolt to 15–20 Nm.
- Strainer holders / eye bolts — install at each straining post (corners, ends, and every 70 m) to provide the anchor point for wire tensioning using a ratchet strainer. Thread the barbed wire through the eye, tension to 200–400 N, and lock the ratchet in position.
Applications
- Solar farm perimeter fence assembly — the complete hardware kit for connecting mesh, posts, and barbed wire into a unified security barrier. Solar farm fencing typically runs hundreds to thousands of linear metres, requiring large quantities of consistent, compatible hardware.
- Industrial and commercial site fencing — warehouses, logistics parks, data centres, critical infrastructure
- Agricultural boundary fencing — estate perimeters, paddocks, vineyard and orchard protection
- Fence maintenance and repair — individual replacement of damaged clamps, caps, or arms without replacing the entire fence section
- Retrofit security upgrades — adding barbed wire arms and anti-tamper bolts to existing fence installations
Material & Durability
All steel accessories carry a hot-dip galvanised or electro-galvanised finish, matched to the corrosion protection standard of the posts and mesh panels they connect. Galvanised steel components deliver a service life of 15–25 years in atmospheric conditions C1–C3 (EN ISO 9223), matching or exceeding the expected life of the fence panels themselves.
Plastic post caps are manufactured from UV-stabilised polyethylene (PE) or polypropylene (PP), resistant to UV degradation, temperature cycling (−30 °C to +80 °C), and impact. The press-fit design requires no tools — simply push onto the post top until the internal ribs grip the tube wall. Replacement caps are available individually for maintenance purposes.
The combination of galvanised steel fixings and galvanised steel posts/mesh eliminates bimetallic corrosion across the entire fence assembly — a common failure mode when mixing stainless steel, aluminium, or brass fixings with galvanised structural elements.
Compatibility
- Fence posts — galvanised round tubular steel, 42.4 mm × 1.5 mm and 48.3 mm × 2.0 mm, lengths 2200 and 3000 mm
- Fence mesh — galvanised welded mesh panels, heights 1500 and 2000 mm, mesh opening 6.5×6.5 mm
- Barbed wire — 2.0 mm galvanised steel, 4-point barbs, 10 kg rolls (~77 m)
- Earthing rod connectors — for grounding the fence line into the site earthing network
- All ULAMEX photovoltaic mounting products — profiles, clamps, fasteners, ballasts
Why ULAMEX
Fencing accessories are the components most likely to be sourced piecemeal from multiple suppliers — a practice that leads to size mismatches, incompatible finishes, and delayed installations. ULAMEX eliminates this risk by stocking a coordinated accessory range designed specifically for the 42.4 mm and 48.3 mm post programme, with guaranteed compatibility across every clamp, cap, clip, and arm. Combined with our fence posts, mesh panels, and barbed wire, you receive a complete fencing bill of materials in one delivery — reducing site downtime and eliminating back-orders for missing hardware.
Frequently Asked Questions
- How many mesh clamps per panel?
- Minimum three per post (top, middle, bottom of the panel). For 2000 mm panels, four clamps per post is recommended for improved rigidity and tamper resistance. With two posts per panel, that is 6–8 clamps per panel.
- Are anti-tamper bolts included?
- Anti-tamper bolts are available as a separate accessory option. Standard orders include regular hex-head bolts; specify anti-tamper if your project requires security fixings.
- Can I use these accessories with non-ULAMEX posts?
- The clamps and caps are sized for standard 42.4 mm (1¼”) and 48.3 mm (1½”) OD round tube — the two most common fence post diameters in Europe. They will fit any manufacturer’s post in these standard sizes.
- Do you sell gate hardware (hinges, latches)?
- Gate hardware is available on request. Contact our sales team with your gate width and type (pedestrian, vehicular, sliding) for component recommendations.
