Engineering Overview & Technical Standards

Architectural and Industrial Roller Shutter Systems

DoorHan roller shutters and rolling door systems provide reliable perimeter protection, storm resistance, solar shading, and burglary deterrence for residential villas, commercial shopfronts, banking institutions, and industrial warehouses. Built from precision-roll-formed aluminum with polyurethane foam core or heavy-duty extruded aluminum profiles, DoorHan shutters deliver exceptional structural rigidity and sleek architectural integration.

Our comprehensive rolling systems portfolio includes compact window shutters, high-security extruded commercial shutters (burglar resistance Class P3/P4), and wide-span rolling doors for industrial facilities.

Key Technical Specifications & Engineering Standards:

  • Profile Variety: Foam-filled roll-formed aluminum slats (39 mm to 77 mm) for thermal insulation; heavy-wall extruded profiles for enhanced physical security.
  • Perforated & Vision Slats: Micro-perforated and rectangular glazed profile options allow natural ventilation and storefront display visibility after hours.
  • Motorized & Smart Automation: Tubular motors with integrated radio receivers, manual crank overrides, central key switches, and remote control transmitters.
  • Anti-Lift Security Locking: Automatic rigid locking springs prevent forced upward lifting of the shutter curtain when fully lowered.
  • Corrosion-Proof Coating: Multi-layer thermosetting polyester powder coating tested against salt spray and UV fading.

Quality Assurance & Engineering Compliance:

DoorHan commercial and industrial roller shutters and steel rolling doors are manufactured in full compliance with European safety standard EN 13241-1 and ISO 9001:2015. Slats and bottom profiles undergo continuous roll-forming inspections, high-tensile wind lock retention tests, and anti-corrosion salt spray verification. We supply civil contractors with detailed guide rail anchoring details, hood dimensions, and electrical motor interface manuals.

DoorHan rolling shutter systems combine clean aesthetic design with dependable engineering, ensuring long-term asset protection and energy conservation.
