Protecting sites against airborne threats
We survey the site, calculate loads, manufacture and install mesh screens, gabion and concrete barriers, and shelters for personnel.

The solution is selected for each site's vulnerable areas: exposed process equipment, tank farms, roofs, entrances and places where people regularly work.
Workshops, exposed process units, compressor stations, finished goods warehouses and loading areas.
StorageTank farms, fuel stores, materials storage yards and loading and unloading racks.
InfrastructureSubstations and transformers, boiler rooms, pumping stations, communications nodes, transport and logistics hubs.
Public FacilitiesAdministrative buildings, schools, hospitals and essential services — protecting entrances and gathering areas.
The stages follow one another. Each relies on the previous stage's findings, so the schedule is calculated after the site survey, not over the phone.
Engineer visit, measurements, identification of vulnerable areas and protection priorities.
Layout plan, load and connection calculations, and materials specification.
Quantity-based estimate, work schedule and site access arrangements.
Fabrication of steel components, delivery and phased installation within agreed work windows.
As-built documentation, structure certificates, scheduled inspections and repairs.
Structures are made for each site: spans, height, loads and connections are calculated for actual site conditions.
Mast-supported mesh above equipment, roofs and access routes. Sections are removable so maintenance and lifting equipment can still operate.
Fragment-resistant walls around perimeters and individual assets, including tanks, transformers, gas regulating units and entrances. Installed without wet construction processes and removable if needed.
Modular and below-grade shelters close to work areas: staff can reach them within one minute. Equipped with ventilation, lighting and an emergency exit.
Available as a separate service when the customer's team or framework contractor handles installation. We provide working drawings and structure certificates.
Mesh and frame sit above the protected area. The survey checks spans, load path, deflection and access to equipment below.
Mesh canopiesGabion or concrete barriers can be considered around specific equipment and openings. Placement is coordinated with vehicle access, maintenance and buried services.
Local barriersA plan identifies priority zones, service routes and work windows. The structure, design scenario and document scope follow that review.

The post's author presents these photos as an example of an external steel frame working during a UAV attack.
VK confirmed an attack on its data center in Leningrad Oblast and said services remained available. The structure's identity and performance have not been independently confirmed.
Photos are embedded from the original post. This is not a Forpost project.
These are the starting points for the design. The final specification is set out in the working documentation for the site.
| Structure | Material | Key Parameter | Standard |
|---|---|---|---|
| Masts and Screen Frame | Tube and sections per GOST 30245-2003 | 6–18 m span | SP 16.13330.2017 |
| Mesh Screen | Polyester cord, steel mesh | 25–50 mm mesh opening | GOST 5336-80 |
| Gabion Structures | Double-twist mesh, stone | 2 × 1 × 1 m module | GOST R 52132-2003 |
| Foundations and Anchoring | B25 concrete, chemical and mechanical anchors | Wind overturning moment | SP 20.13330.2016 |
| Personnel Shelters | Reinforced concrete rings, blocks and steel frame | At least 1.0 m of earth cover | SP 88.13330.2022 |
| Welded Joints | Semi-automatic CO₂-shielded welding | Weld inspection, visual and dimensional checks | GOST 14098-2014 |
| Corrosion Protection | Primer-enamel, hot-dip galvanizing | 80–120 µm coating thickness | GOST 9.402-2004 |
Structures are made for each site: spans, height, loads and connections are calculated for actual site conditions.
We identify specific zones first: exposed equipment, tanks, roofs, entrances and work areas. We then check whether a physical barrier can be installed while preserving maintenance and emergency access. Protecting one asset does not mean protecting the entire site.
Send a site plan or sketch, photographs, approximate dimensions, a list of critical assets and the site location. Vehicle routes, underground utilities, maintenance areas and permitted work windows are also useful. A preliminary assessment does not replace a survey and calculations.
FPV and other multirotor aircraft, and fixed-wing UAVs, are assessed as different impact scenarios. The likely approach, contact point and consequences for each asset matter more than a model name alone.
There is no universal guarantee. The mesh, attachments, deflection, supports, foundations and asset layout all need to be checked. Resistance to a defined scenario must be demonstrated for the whole system, not just a mesh sample.
That is a separate design scenario. The span arrangement, supports or local barriers may need to change. The solution follows a site survey and agreed performance criteria.
Mesh is selected together with cables, connections and the supporting frame for the agreed scenario and operating environment. Opening size alone does not establish canopy resistance.
Setback depends on asset geometry, potential system deflection, the agreed impact scenario and maintenance access. There is no universal safe distance; the project sets it after measurement and layout review.
Only after the building capacity, connections and load path have been checked. If the existing structure is unsuitable, independent supports and foundations can be considered. The decision belongs in the working drawings.
Site loads and exposure conditions inform the frame, connections, foundations and protective coating. Applicable Russian building standards are used for structural and environmental checks. These checks do not establish UAV impact resistance.
The sequence is agreed with the operations team after the survey. Vehicle routes, emergency and maintenance access, hot-work restrictions and permitted shutdown windows are considered. Whether a zone can stay operational is decided for that site.
The drawings identify covered roofs, equipment and openings, as well as areas outside the protection boundary. Side screens, local barriers or shelters may be considered separately. A general visualization does not imply coverage of the whole facility.
Local gabion or concrete barriers and personnel shelters may be considered. Their position and required performance are set separately from the canopy for an agreed scenario. No single arrangement removes every consequence of an impact.
Yes, design work can be discussed separately from fabrication and installation. The scope of survey, calculations, drawings and support is set in the brief and proposal.
The contract sets the deliverables, typically a layout, design inputs, working drawings, specifications and material documents. If installation is included, as-built records and an inspection procedure are defined separately.
Support and barrier positions are checked against the design, along with attachments, mesh tension, clear routes, material records and the maintenance procedure. The project and contract set the inspection scope.
Restrict access to the affected zone and inspect the mesh, cables, fixings, supports and foundations. Record defects; continued use and replacement work depend on the design procedure and inspection results.
Only for a defined structure and impact scenario supported by appropriate analysis or testing. Sizes and materials shown on this site are indicative and do not themselves prove impact resistance.
Shelters and access routes are considered separately from equipment protection. Capacity, location, entrances, ventilation, communications and operating procedure are defined for the site.
Leave your contact details, location, site type and the zones requiring protection in the form. We will clarify the inputs and survey scope; final parameters and pricing follow a site review.
Tell us the site type, its area and what needs protection first. The survey is the basis for the estimate, so accurate details help us prepare figures sooner.
