Advanced Fire Protection for Large-Scale Openings

In today's evolving building landscape, architects, consultants, and facility managers face increasing demands to balance safety, functionality, and design flexibility. Critical infrastructure facilities such as data centers, airports, government buildings, and large commercial developments require fire-rated solutions that can protect occupants and assets while accommodating larger-than-standard openings.

To address these requirements, ASSA ABLOY introduces an innovative oversized hollow metal single door solution, tested to achieve an impressive 120-minute fire rating, setting a new benchmark for safety and performance in large-opening applications.

Engineered for Enhanced Fire Protection

Fire-rated doors play a vital role in compartmentalizing buildings and slowing the spread of fire and smoke during emergencies. ASSA ABLOY's new oversized hollow metal door solution has been rigorously tested in accordance with the UL 10C fire test standard, providing assurance that it can withstand fire exposure for up to 120 minutes.

This certification demonstrates the door's ability to maintain its integrity under extreme conditions, helping building owners and operators meet stringent fire safety requirements while supporting occupant protection and business continuity.

Designed for Large and Demanding Openings

Many critical facilities require larger access points to accommodate specialized equipment, operational needs, or architectural considerations. Traditional fire-rated door solutions can often be restrictive when it comes to size limitations.

ASSA ABLOY's advanced solution addresses this challenge by offering dimensions of up to 1,400 mm wide and 3,200 mm high, making it ideal for projects that demand oversized fire-rated openings without compromising compliance or performance.

This capability is particularly valuable in environments such as:

• Data Centers – Supporting the movement of large IT equipment and infrastructure components.
• Airports – Meeting the operational and safety requirements of high-traffic facilities.
• Government Buildings – Delivering robust fire protection for secure and critical environments.
• Commercial Developments – Providing flexibility for large openings while maintaining fire safety standards.
• Residential Projects – Offering enhanced protection where larger door configurations are required.

Exceptional Configuration Flexibility

Modern construction projects often require customized solutions that align with unique project specifications. ASSA ABLOY's oversized hollow metal door system is engineered with high configuration flexibility, enabling architects and designers to integrate fire protection seamlessly into a wide range of building designs.

The solution combines robust construction, code-compliant fire performance, and adaptability, helping stakeholders achieve both functional and aesthetic objectives without sacrificing safety.

Meeting the Needs of Tomorrow's Infrastructure

As infrastructure becomes increasingly complex, the demand for larger, more resilient fire-rated openings continues to grow. ASSA ABLOY remains committed to advancing door and opening solutions that address emerging industry challenges while supporting compliance with international safety standards.

With its 120-minute fire-rated oversized hollow metal single door, ASSA ABLOY delivers a solution that brings together fire protection, operational efficiency, and design flexibility—empowering architects, contractors, and facility owners to create safer environments for the future.
