Passive protection systems

Physical protection for assets exposed to UAV and FPV drone attack, blast overpressure and high-velocity fragments. Every configuration is sized from the threat definition — charge weight, approach speed, required standoff and the geometry of what sits behind the barrier.

Passive protection systems are delivered together with Flow&Art Space Engineering, combining their protection system design with Doorsmar engineering, fabrication and site delivery.

Engineered end to end

Every door is designed and structurally verified in-house. Fabrication is carried out to Doorsmar drawings and specifications, with inspection and installation under Doorsmar supervision.

01Design & structural analysis — static and dynamic

Every door starts as a project-specific calculation. Leaf geometry, plate thicknesses and stiffeners are sized against the specified blast or pressure load, with static and dynamic checks against internationally recognised response limits.

02Steel fabrication to Doorsmar specifications

Fabrication is carried out to Doorsmar drawings and welding specifications. Materials are certified and traceable, and every leaf and frame is inspected before release.

03Independent laboratory testing

Door types are validated by physical testing at independent accredited laboratories. Test evidence is referenced in project documentation and shared with qualified parties on request.

04Installation and commissioning

Doors are installed and commissioned under Doorsmar supervision. Anchoring, alignment, sealing and hardware adjustment are verified on site before handover.
