Industrial Concertina Barbed Wire – 1000mm High-Tensile Galvanized Steel Security Coils
When safeguarding strategic perimeters and high-risk federal lines, regular low-carbon steel wires offer completely insufficient physical defense. Our premium Concertina Barbed Wire structure provides the definitive answer to heavy-duty territorial integrity and area denial. Purpose-built to meet rigorous material blueprints, these large-format 1000mm coils are fabricated with a reinforced 3.73mm high-tensile core wire that maintains its elastic profile under intense external duress. By weaving a robust double-strand 2.0mm barbed wire layout across an interlocking cross matrix, this structural defense line delivers exceptional physical deterrence and long-term boundary security.
Advanced Mechanical Engineering of Large-Format Fencing Barriers
Primary Tactical Performance Attributes & Specifications:
- Thick 3.73mm High-Tensile Core Wire: Formed using premium-grade structural carbon steel wire rated at a breaking threshold ≥ 1100 N/mm² to prevent rapid shearing attempts.
- Rigid 5-Clips Cross Configuration: Incorporates 5 heavy steel locking clips per spiral loop, transforming 68 continuous coils into a robust three-dimensional spatial block that stops manual prying gaps.
- Optimized 101mm Barb Pitch: Sharp 4-point barbs are twisted firmly at exact 101mm structural intervals onto a 2.0mm strand base to ensure continuous anti-climb skin hold.
- Calibrated Heavy Duty Loading Weights: Engineered to standard 68-loop yields providing a solid mass framework (~27 kg per coil) that resists structural bending under strong winds or dynamic ground debris loading.

Strategic Infrastructure Border Fortification
Our large-format Concertina Barbed Wire arrays are systematically deployed to secure infrastructure perimeters worldwide. Because the 1000mm expanded cross-section provides immense spatial depth, these helical coils perform perfectly across remote frontier zones, railway buffers, and industrial airport boundaries. The calibrated 5-clip interlocking distribution ensures seamless linear movement when pulled open, enabling construction teams to roll out hundreds of meters rapidly and fasten the baseline rows firmly using heavy steel earth staples or structural Y-brackets under high dynamic wind stresses.
B2B Supply Chains, Bulk Compression & Maritime Freight Bracing
Operating as a reliable, large-scale industrial manufacturing plant for global building supply conglomerates and international defense contractors, we enforce strict protocols for shipping stability. Uncompressed 1000mm coils waste vast amounts of container space and are prone to interlocking damage during transit. To eliminate this issue, our heavy-duty hydraulic mechanical arrays compress each 68-loop coil into a rigid cylinder secured firmly with structural steel banding. Wrapped inside dual-layered waterproof polyethylene woven bags, our products clear long intercontinental shipping routes flawlessly, ensuring high container utilization rates and rust-free inventory arrival.
Frequently Asked Questions (FAQ)
Q1: Why is an 1100 N/mm² tensile strength wire necessary for the inner core of this concertina fence?
A: Standard low-carbon steel wires can be cut rapidly with simple pocket pliers or bent out of shape permanently. Our premium high-tensile carbon core wire possesses an intense structural spring hardness that destroys standard manual wire hand-cutters on contact, keeping the expanded loop barrier upright and active under active tampering.
Q2: What is the benefit of your 5-clip interlocking matrix compared to a basic 3-clip layout?
A: A basic 3-clip coil stretches loosely and leaves wider spacing clearances that intruders can spread open. Our high-density 5-clip alignment tightly locks overlapping wire arcs together into a rigid, non-collapsible three-dimensional diamond obstacle wall. This eliminates gaping apertures and bars scaling attempts, even if intruders utilize heavy protective body blankets.
Q3: How many running meters does a single 1000mm, 68-loop concertina wire roll efficiently cover?
A: For optimal security density and continuous anti-climb mechanical stability, this custom 68-loop coil is engineered to cover approximately 12 to 14 linear meters per roll. Over-extending the coil significantly past 14 meters widens the spacing gaps between loops, reducing the physical spatial deterrence and compromising the structural security rating of your fence line.
Q4: Can your manufacturing lines support private label OEM packing and fulfill large multi-ton government bidding timelines?
A: Yes, absolutely. We regularly fulfill large OEM/ODM volume requirements for international engineering distributors and infrastructure bidding contracts. Operating multiple high-speed automated drawing and winding press matrices, we deliver comprehensive documentation packages, mill test sheets, and consistent monthly volumes of 800+ tons to secure delivery schedules.
