What is an anti-climb fence?
An anti-climb fence is a rigid welded wire mesh panel whose openings are only 0.5 inch (12.7 mm) tall, so fingers and shoe tips cannot get a grip. Una Wire Products makes it in 4 ft x 8 ft sheets with 2" x 0.5" or 4" x 0.5" openings, factory-direct in Quezon City. Call (02) 8260-0181 for the current price.
What is an Anti-Climb Fence?
Most fences are easy to beat. Chain-link (cyclone wire) has diamond openings that act like a ladder, and a low wall can be hopped with a boost. An anti-climb fence is built to remove the hand and foot holds that make those fences easy to climb. Its horizontal wires sit only half an inch apart, which is narrower than a finger and far narrower than the toe of a shoe. The vertical wires are spaced 2 inches or 4 inches apart and every crossing is welded, so the panel stays flat and rigid instead of sagging like rolled wire.
The result is a fence that is hard to climb, hard to cut and easy to see through. It is used where a property needs real security, not just a boundary marker: warehouses, factories, school and church compounds, utility and telecom sites, car and equipment yards, and homes in areas with theft problems.

How an Anti-Climb Fence Helps Secure Your Property
A security fence has one job: make it slow, loud and obvious when someone tries to get in. An anti-climb panel helps in five ways.
- No grip, no foothold. The 0.5-inch gaps are too narrow for fingers or the toe of a shoe, so a person cannot pull or step their way up the way they can on chain-link or a welded-wire livestock fence. A would-be intruder has to bring a ladder, which takes planning, makes noise and is easy to spot.
- Hard to cut through. The gaps leave almost no room to get cutter jaws around one wire. Cutting takes longer, takes tools the intruder must carry in, and makes noise, which buys time for a guard, a camera or a neighbor to notice.
- A rigid panel, not a sagging roll. Welded 4 ft x 8 ft sheets bolted to posts stay flat. They cannot be pulled apart, lifted at the bottom or pushed down like loose wire, so the fence keeps its shape for years.
- You can still see through it. Unlike a concrete wall, the mesh is open, so guards and CCTV keep a clear view of both sides of the line. Intruders have nowhere to hide while they work, and you do not lose the airflow or daylight a solid wall blocks.
- A visible deterrent. Most break-ins are opportunistic. A tall, tight, rigid fence tells a thief the property is looked after and sends them to an easier target next door.
No fence is a guarantee, and the strongest setups layer protection: the fence, lighting, cameras and people. An anti-climb fence is the part that stops an intruder from simply climbing over and gives you time to react.
Where Anti-Climb Fencing is Used
- Factories, warehouses and logistics yards. Protects stock, vehicles and machinery from theft, especially along the back and sides of a compound that cannot be watched all day.
- Construction material yards and equipment depots. Rigid panels can be installed quickly and re-used or relocated when the site moves.
- Schools, churches and institutional compounds. Keeps the boundary secure while staying open and welcoming to look at, unlike a high blank wall.
- Utility, telecom and power sites. Substations, cell towers, pumping stations and water facilities, where unauthorized access is a safety risk as well as a theft risk.
- Commercial properties and subdivisions. Gates, rear boundaries, parking and generator areas where visibility matters as much as strength.
- Homes and villas. Back and side boundaries that face vacant lots, creeks or alleys, where a standard fence has been climbed or cut before.
Anti-Climb Fence vs Other Fence Types
| Feature | Anti-climb fence | Cyclone wire | Steel matting fence | Barbed wire |
|---|---|---|---|---|
| Climbing | Very hard, no finger or toe hold | Easy, diamond openings are a ladder | Possible, openings are 2 in or larger | Painful, but it can be crossed |
| Cutting | Slow, little room for cutter jaws | Quick with pliers or cutters | Moderate | Quick |
| Rigidity | Rigid flat panel | Flexible roll, can sag | Rigid flat panel | Strands, can be spread |
| Visibility | Open, see-through | Open, see-through | Open, see-through | Open, see-through |
| Cost | Higher, for real security | Low | Moderate | Lowest |
See our guides: steel matting vs cyclone wire fence, cyclone wire and barbed wire. Many owners combine two of these, for example anti-climb panels with barbed wire along the top.
Installation Tips
- Use strong posts. Panels are rigid and carry weight, so use steel or concrete posts set in concrete footings. Place a post at each 4 ft panel joint, and set corner and gate posts deeper and braced.
- Clamp, don't tie. Fix each panel to its posts with bolted clamps or plates, every 600 mm or so, with the nuts on the secure side of the fence so they cannot be undone from outside. Peen or weld the bolt ends for high-security sites.
- Close the bottom gap. Keep the lower edge close to the ground or set it on a low concrete curb so nobody can crawl or dig under. On uneven ground, use stepped panels rather than leaving a gap.
- Add height where it matters. Two or three strands of barbed wire on outward-angled brackets above the panels make the fence harder to throw a ladder or blanket over. Check your local government unit's rules on fence height and barbed wire before building.
- Plan the gates. Gates should use the same mesh and be hinged and latched from the secure side. Una Wire can help you work out the number of panels; see how to measure your fence perimeter or use the fence calculator.

Frequently Asked Questions
What is an anti-climb fence?
An anti-climb fence is a welded wire mesh panel with very narrow horizontal openings, 0.5 inch (12.7 mm) tall, so a climber cannot get fingers or the toe of a shoe into the mesh. Unlike a cyclone wire fence, which people can scale easily, there is nothing to grip or step on.
What are the opening and panel sizes?
Una Wire Products supplies anti-climb fence panels with 2 inch x 0.5 inch or 4 inch x 0.5 inch openings, in 4 ft x 8 ft sheets (about 1.22 m x 2.44 m). Call (02) 8260-0181 to confirm current availability.
Is an anti-climb fence hard to cut?
The 0.5 inch openings leave almost no room to get the jaws of a bolt cutter around a single wire, so cutting through takes much longer and makes more noise than cutting chain-link or barbed wire. No fence is uncuttable, which is why it works best together with good lighting, a camera or a guard.
What is the difference between the 2 inch and 4 inch openings?
Both have the same 0.5 inch gap between the horizontal wires, which is the part that stops climbing. The 2 inch x 0.5 inch panel has more vertical wires, so it is tighter and heavier. The 4 inch x 0.5 inch panel has fewer vertical wires, so it is lighter and costs less steel while still giving no finger or toe hold.
Can I see through an anti-climb fence?
Yes. The mesh is open, so you keep a clear view of the property from outside and inside. This is useful for guards and cameras, and it avoids the shut-in feeling of a solid wall.
How tall is one panel and how do I get a taller fence?
One 4 ft x 8 ft sheet standing upright gives a section 8 ft (about 2.4 m) high and 4 ft wide. For extra height or deterrence, many owners add two or three strands of barbed wire on outward-angled brackets above the mesh.
How much is an anti-climb fence panel?
Price depends on the opening size, wire thickness, finish and quantity. Call (02) 8260-0181 or send the quote form with the number of panels and your delivery location and we will quote you the same day.
