Robust outa dor 120 steel fire rated steel doorsets

Outa-Dor 120 - 2 Hour Fire Doorset

The Outa-Dor 120 is the ideal heavy-duty external doorset for commercial facilities that require a balance of extended fire protection and everyday usability. Delivering a certified 2 hours (120 minutes) of fire resistance, it provides a robust defense against external threats while seamlessly handling the high traffic demands of modern business environments.

Engineered for locations where the extreme 4-hour rating of the Outa-Dor 240 may be excessive, this model hits the compliance sweet spot for most industrial units, retail back-of-house areas, and public building exits. It combines the weather-defying properties of Magnelis® steel with advanced thermal infill options, ensuring your building envelope remains secure, insulated, and compliant.

Defensive Features

• Optimized Fire Rating: Fully tested to BS EN 1634-1, providing 120 minutes of integrity (E120) and optional insulation (EI ratings available with specific cores). This offers ample time for evacuation and asset protection without over-specification.

The Outa-Dor 120 is the workhorse of external fire protection for the UK commercial sector. Delivering a certified 2-hour (120-minute) fire rating, it offers a balanced solution that exceeds standard 60-minute requirements without the specialist expense of 4-hour barriers. It is the "go-to" specification for facilities managers and architects needing robust, compliant, and durable external doors.

Commercial & Retail

For modern commercial premises, the Outa-Dor 120 provides essential protection for back-of-house areas and loading zones:

• Shopping Centres & Supermarkets: Ideal for service yard access and delivery corridors where fire separation from the main building structure is critical.

Industrial & Warehousing

The Outa-Dor 120 withstands the harsh realities of industrial environments:

• Manufacturing Plants: Protects external plant rooms housing compressors, boilers, and switchgear that require 2-hour containment to prevent fire spread to the main factory floor.
• Distribution Centres: Essential for protecting fuel storage areas and battery charging zones for forklift fleets.
• Workshops: A durable alternative to timber for external personnel doors, resisting oil, grease, and heavy impact while maintaining fire integrity.

Public Sector & Education

Safety and durability make the Outa-Dor 120 a preferred choice for public funding projects:

• Schools & Colleges: Used for external plant rooms and kitchen deliveries, where the robust steel construction resists heavy daily use and potential student misuse.
• Hospitals: Critical for protecting medical gas stores and backup generator rooms that ensure hospital continuity during emergencies.
• Community Centres: Provides a low-maintenance, secure fire exit that won't rot or warp, reducing long-term facilities management costs.

Performance Ratings

Installation & Assembly

Our Robust steel doorsets are engineered to minimize on-site labour and eliminate the common headaches associated with traditional door installation. Every unit is designed with a "Single Fix" philosophy, meaning the door is supplied as a complete, ready-to-fit system rather than a collection of parts.

Pre-Assembled Convenience

Unlike timber doors that require separate frame assembly, hanging, and hardware fitting, our steel doorsets arrive fully factory assembled. This means:

• Pre-Hung Leaf: The door leaf is already mounted within the frame on high-performance stainless steel hinges.
• Hardware Fitted: Locks, panic bars, and closers are pre-installed and tested in our factory, ensuring perfect alignment and operation out of the box.
• Reduced Downtime: This "plug-and-play" approach drastically cuts installation time, allowing a typical single door to be fitted in less than 60 minutes by a competent installer.

Adjustable Frame System

We understand that structural openings are rarely perfect. Our unique installation system is designed to handle real-world site conditions without the need for excessive shimming or packing:

• Variable Sub-Frame: The frame features an adjustable profile that can accommodate wall tolerance variances of -0mm to +30mm. This ensures a secure fit even in uneven openings.
• Adjustable Fixing Feet: Each jamb is fitted with 4 adjustable fixing feet (8 per doorset). These allow installers to quickly level the frame and secure it firmly into the aperture using the provided 12mm Allen key.
• No Shims Required: The integrated adjustment system removes the need for fiddly packers, creating a cleaner, more solid fixing point directly into the substrate.

Installation Kit Included

To further simplify the process, every doorset comes with a comprehensive installation kit containing:

• 12mm Allen Key: For rapid adjustment of the fixing feet.
• Touch-Up Paint: Matched to your door's colour for covering any minor installation marks.
• Clear Mastic: For weather-sealing external perimeters (where applicable).
• Drill Bits: Specialist bits suitable for concrete or steel fixing, ensuring you have the right tools for the job.
