Why Choose Steel?

• Unmatched strength and durability: Steel construction resists forced entry, physical damage, and daily wear better than timber or composite alternatives. It ensures lasting performance in demanding conditions.
• Superior security: Steel doors are highly secure by design, with robust multi-point locking options and compatibility with advanced access control hardware.
• Minimal maintenance: Unlike timber, steel will not warp, rot, split or require regular re-coating or sealing, even in exposed external locations.
• Custom appearance: Steel doors can be powdercoated to almost any finish, including modern colours and textures—blending seamlessly with building architecture and delivering aesthetic appeal alongside practical performance.
• Fire and weather resistance: Steel provides natural fire resistance and, with suitable hardware and seals, ensures excellent protection from wind, rain, and temperature extremes.

Legal Requirement & Compliance

Installation of emergency fire exit doors is a legal requirement in the UK for any building regularly occupied by more than five people, and for virtually any premises used by the public during operational hours. Correctly specified exit doors are fundamental to safe evacuation strategies, aid compliance with fire safety legislation, and are frequently scrutinised during safety inspections.

• Doors must always be clearly marked and unobstructed, with easy access and clear signage indicating their location.
• Escape doors should open easily in the direction of exit and be free from internal locking mechanisms when in use.
• Regular maintenance and checks are essential to ensure escape routes remain effective and compliant.

Outa-Dor Exit steel doorsets offer the ideal solution—delivering certified performance, unrivalled durability, and long-term security, making them the preferred choice for modern fire safety compliance in all building types.
