Physical interception
N-PE / N-AR drone interception nets
Passive interception panels for refineries, tank farms, factory roofs and high-value buildings. Engineered from HMPE or aramid rope to stop a drone before it reaches the asset.
Interception nets
Not a perimeter fence. A last layer.
A detection system tells you a drone is coming. A net makes sure it does not arrive. Each panel is designed around the asset, the approach path and the drone class — with anchor points, standoff distance and wind load calculated for the site.
- Custom mesh and panel size
- HMPE for UV and abrasion; aramid for heat
- Engineered anchor and tension system
- Removable sections for maintenance access
- Designed for refinery, industrial and building envelopes
Interception nets
Choose the right fibre.
Both materials are high-strength. The difference is how they behave outdoors, under heat and at the anchor points.
| HMPE | Aramid | |
|---|---|---|
| Density | 0.97 g/cm³ — floats | 1.44 g/cm³ — sinks |
| Strength, same diameter | Comparable to steel wire | 5–6× steel wire |
| Modulus | High | 2–3× steel wire |
| Elongation at break | 3–4% | 3.5–5% |
| Heat behaviour | Melts at 144–155 °C | Decomposes around 500 °C |
| UV resistance | Excellent | Weak |
| Abrasion resistance | Excellent | Normal |
| Best for | Long-term outdoor, coastal and humid sites | High-temperature, fire-exposed areas and reinforced edges |
Interception nets
What we need to engineer a net.
- Asset geometry and approach paths
- Drone mass and impact speed
- Wind and snow load
- Anchor structure and standoff distance
- Maintenance access and drainage
Scope
- Site survey and panel layout
- Custom panel fabrication
- Anchor and tension hardware
- Installation supervision
- Spare panels and repair kit
Nets are passive physical protection. They do not detect or identify targets; pair them with radar and EO/IR for a complete layered system. Net design is project-specific and subject to engineering review.

Send the asset drawing.
A net is only as good as its anchorage. Share the building or tank farm layout and the drone class, and we will define the panel grid and support concept.
