Steel blast resistant and tunnel wind pressure doors — designed, analysed, manufactured and installed by Doorsmar.
Every door in the BD range is positioned on a single scale — from certified tunnel wind pressure to extreme blast loads.
Certified against aerodynamic pressure loads in rail and metro tunnels. Independently tested at an accredited laboratory.
Single and double leaf hinged doors for shelters, industrial plants and critical infrastructure. Sandwich to full-plate construction.
Heavy sliding doors for large openings where leaf weight rules out hinges. Manual and motorised operation.
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.

Tensioned steel mesh and cable-net envelope on structural towers. Stops the aircraft before it reaches the asset and creates a calculated standoff distance.

Outer fence line, calculated standoff zone and an armour steel plus UHMWPE build-up at the protected surface. Nothing comes off the protected face.

Bolted, flat-packed frames with tensioned wire mesh. No welding, no heavy foundations — the enclosure follows the asset when it moves.
Passive protection systems are delivered together with Flow&Art Space Engineering, combining their protection system design with Doorsmar engineering, fabrication and site delivery.
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.
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.
Fabrication is carried out to Doorsmar drawings and welding specifications. Materials are certified and traceable, and every leaf and frame is inspected before release.
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.
Doors are installed and commissioned under Doorsmar supervision. Anchoring, alignment, sealing and hardware adjustment are verified on site before handover.
Doorsmar's founding team has worked on blast resistant door programmes across energy, defence and critical infrastructure since 2018 — from international manufacturing inspection to on-site installation management.
Approximately 200 blast resistant doors across pipeline facilities. Design and manufacturing carried out in South Korea with on-site inspection; installation across Türkiye delivered under our team's project management.
Magazine and ammunition storage door package for a military airbase programme in the Gulf region, delivered to military munitions storage standards.
Blast resistant doors for a leading Turkish defence industry manufacturer — domestic design, production and installation delivered as a complete scope.
Blast resistant door package for a military facility programme in Libya — design, production and site installation delivered by Doorsmar as a complete scope.

Projects from 2018–2023 reflect work delivered by our founding team in previous corporate roles.
Test reports and technical documentation are not published. Full certification data, drawings and calculations are shared with qualified project parties under NDA.
