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.

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.
