Why buy the Louvred Steel Doors?

When ventilation is just as critical as security, the Louvered Steel Door offers a high-performance solution that delivers both. Ideal for environments where air flow and temperature regulation are essential, these doors ensure reliable performance without compromising on strength or durability. Whether you’re securing a plant room, substation, or commercial site, a louvered steel door from Security Direct is a proven, practical choice.


Benefits

  •   Continuous Ventilation: Allows airflow to cool or ventilate equipment rooms, warehouses, and utility spaces.
  •  Durable Steel Construction: Manufactured from galvanised or stainless steel for long-lasting, corrosion-resistant performance.
  •  Security + Airflow: Combines medium security features with high open-air ventilation ratings — perfect for balancing protection and climate control.
  •  Customisable Design: Bespoke sizes and configurations (solid/louvre combinations) available to meet site-specific needs.
  •  Weather Protection: Integrated rain-drip cills and insect mesh options provide protection against water ingress and pests.
  •  Acoustic Options: Optional acoustic louvres help reduce noise transmission from plant or machinery inside.
     

Operation

  •   Manual or Electric Locking: Typically fitted with secure mechanical locks (3-point or 5-point), with digital or keypad upgrades available.
  •  Hinged for Easy Access: Outward-opening design with anti-tamper fixings, suited for frequent maintenance access.
  •   Louvers Built-In: Integral louver panels welded or mechanically fixed into the leaf and/or overpanel for airflow.
     

Applications

Louvered steel doors are widely used in both commercial and industrial environments where ventilation and security are equally important:

  •   Plant and Boiler Rooms
  •  Electrical Substations
  •  Bin Stores
  •  Car Parks and Basements
  •  Data Centres and Comms Rooms
  •  Chemical Storage Areas
  •  Utility Enclosures
     

Certifications

  •   CE Marked: Conforms to BS EN 14351-1 for external doorsets.
  •   Security Options: Can be upgraded to LPS 1175 (SR1 or SR2) specifications on request.
  •  Fire-Rated Options: Some models available with limited fire integrity or smoke resistance when ventilation panels are combined with fire-rated elements (subject to certification).
  •  Ventilation Performance: Louvre blades engineered for free airflow of up to 50% depending on pitch and spacing.

Information

Security Features

  •   Manufactured from robust galvanised or Zintec-coated steel for superior strength and resistance to forced entry.

Safety Features

  •   Integrated intumescent seals and fire-rated options (up to 240 minutes with select models) for dual ventilation and fire performance.
  •  Louvered panels allow air flow while maintaining safety, minimizing heat buildup and pressure in plant or boiler rooms.
  •  Options for vision panels or transoms improve safety through visibility and lighting.
  •  Emergency exit hardware (push bars or touch bars) available for fire escape doors.

 Insulation & Energy Efficiency

  •   Designed for air circulation—ideal for plant rooms, generator enclosures, and substations requiring passive ventilation.
  •  Though not thermally insulated, they assist in managing internal temperatures by dissipating heat.
  •  Acoustic louvre variants available for noise-sensitive environments 
  •  Brush seals or weather seals optional for perimeter draught protection.

Design & Customisation

  •   Wide range of standard and non-standard RAL/BS colour finishes, including marine-grade coatings for coastal applications.
  •  Choice of frame and panel thicknesses (typically 1.2mm to 2.0mm) based on project specification.
  •  Modular louvre infill or full louvred leaf designs available.
  •  Optional features include vision panels, rain deflectors, letter plates, kick plates, and powder-coated finishes.
  •  Sleek, flush finish with minimal visible fixings for a professional aesthetic.

Operation & Controls

  •   Supplied as manual hinged doors, available as single, double, or leaf-and-a-half configurations.
  •  Available as inward or outward opening.
  •  Can be combined with door automation systems where required (especially for large or secure access areas).
  •  Operable with standard keys, coded locks, or access control integration (electronic strike, maglocks).

Installation & Warranty

  •   All doors are made-to-measure to meet precise site requirements.
  •  Installation flexibility: suitable for internal or external use, with reveal fix or face fix options.
  •  Strongdor offers 10-year anti-corrosion warranty on steel doors when factory powder-coated.
  •  Factory-fitted hardware reduces site fitting time and increases consistency.

Lead Time & Common Applications

  •   Standard lead time: typically 10–15 working days, though fast-track options are available for urgent requirements.
  •  Popular in plant rooms, substations, bin stores, generator housings, HVAC enclosures, and data centres.
  •  Suitable for both commercial and industrial sectors requiring airflow without compromising security.
