This page details the engineering parameters of tall black chain link fence systems manufactured for direct factory supply, including gate assemblies. Information focuses on measurable characteristics that influence selection, installation, and long‑term performance.
Overview
Tall chain link fences are commonly specified for perimeter security where visibility and airflow are required. Heights typically range from 2.4 m to 4.2 m, with wire gauges selected to meet specific load and impact criteria.
The black finish is achieved through a polyvinyl chloride (PVC) coating applied over a galvanized steel core, providing a uniform color and added corrosion barrier.
Specifications
Key dimensions include mesh opening, wire diameter, and post spacing. These values determine the fence’s rigidity, climb resistance, and wind load capacity.
- Mesh opening: 50 mm × 50 mm (standard) or 38 mm × 38 mm for higher security.
- Wire diameter: 2.5 mm to 4.0 mm depending on gauge selection.
- Post spacing: 2.5 m to 3.0 m for line posts; gate posts spaced according to gate width.
Material and Finish
The core wire is low‑carbon steel, hot‑dip galvanized to a minimum zinc coating of 55 g/m² (ASTM A123). Over the galvanized layer, a PVC coating of 0.35 mm thickness is extruded, yielding a total coated wire diameter that meets the specified gauge.
The PVC formulation includes UV stabilizers to limit color fading; accelerated weathering tests show <5 % color change after 1000 h UV exposure.
Gate Options
Gate leaves are fabricated from the same coated wire mesh, framed with rectangular steel tubing. Gate width can be customized from 0.9 m for pedestrian access up to 6.0 m for vehicle passages.
- Frame thickness: 2.0 mm wall thickness for widths ≤3.0 m; 2.5 mm for wider leaves.
- Hinge type: ball‑bearing hinges rated for 150 kg leaf weight.
- Locking provisions: provisions for padlock, mortise lock, or electric strike.
Applications
Industrial facilities select tall black chain link fences when a balance of security, visibility, and low maintenance is required. The open mesh allows CCTV cameras and motion sensors to operate without obstruction.
Typical sites include logistics yards, substations, water treatment plants, and perimeter zones around manufacturing plants where a height of 3.0 m or more deters climbing while still permitting airflow for ventilation.
Quality Control
Each production lot undergoes dimensional verification, coating adhesion testing, and tensile strength checks. Wire tensile strength is measured per ASTM A370, with typical values exceeding 350 MPa for the steel core.
Coating adhesion is assessed by the cross‑hatch test (ASTM D3359); a rating of 4B or higher indicates adequate bonding. Zinc coating weight is verified by gravimetric methods to meet the minimum 55 g/m².

FAQ
Can dimensions be customized?
Yes. Fence height, mesh size, wire gauge, and gate width are adjusted per project specifications. Provide required measurements and load conditions for a quotation.
What information is required before quotation?
Needed details include overall perimeter length, desired height, gate quantities and widths, soil conditions for post setting, and any specific coating or color requirements.
How is quality inspected?
Each batch receives dimensional checks, coating adhesion (cross‑hatch), zinc weight verification, and tensile strength testing. Test reports are available upon request.
