FM4991 — Proven System Strength: Shanghai Tengxi Helps Indian Project Successfully Pass 4

FM4991 System Forging Strength: Shanghai Tengxi Helps Indian Project Successfully Pass Hour Firestop Test

• High-standard challenge from India

In international industrial safety cooperation, every cross-border commission is a dual test of systems and professionalism.

Recently, Shanghai Tengxi Construction Engineering Co., Ltd. (TKC), relying on the FM4991 firestop contractor system and mature engineering and technical capabilities, successfully assisted an Indian client in completing a highly challenging task — designing and implementing a busbar (ISO 834-1 slot penetration firestop solution), and under third-party witnessing, smoothly passing the hour fire resistance test standard.

• Professional design and engineering judgment under the FM4991 system

Faced with the high standard requirement of hour fire resistance, the Shanghai Tengxi team took the FM4991 quality management system as the core framework, and, comprehensively applying FM(EJ) national carbon certified product engineering judgment diagrams, developed a customized firestopping system.

The solution adopts a multi-layer collaborative protection structure, achieving the dual performance objectives of temperature rise control and integrity retention through a combination of fire wrapping, sealing filling, coating sealing, and structural reinforcement (T-Rating)(F-Rating).

At the same time, the Tengxi team strengthened material performance and optimized construction details according to project characteristics to ensure the system remains stable and sealed under 240 minutes of high temperature exposure.

• From design to witnessing: the power of systematized execution

During project execution, the Shanghai Tengxi team provided full technical support, supervised on-site installation and sample preparation, ensuring construction steps fully complied with FM standard requirements. All construction records, material inspections, and installation parameters were managed and archived according to FM4991 system documentation, ensuring the process is traceable and the results verifiable. Under the witness of an Indian third-party testing agency, the sample underwent the hour high-temperature fire test:

(F-Rating) ◆ Structural integrity met the standard
(T-Rating) ◆ Temperature rise control qualified
◆ No cracks, no spalling, no penetration

The final test was a complete success, and the client gave high praise to Shanghai Tengxi’s professional service and engineering quality.

• Results and significance: bringing standards to international project sites

The success of this Indian project under FM demonstrates Shanghai Tengxi’s international engineering capability under a certified system. From solution design to test passing, Tengxi, with a professional and rigorous FM4991 management process, completed a representative case of Chinese fire protection technology going global.

This not only verifies the company’s comprehensive strength in firestop design, material integration, and system validation, but also reaffirms the corporate belief that standards win trust and systems ensure quality.

• Conclusion: making safety standards a common language

In the future, Shanghai Tengxi will continue to take the FM4991 system as the technical core and work with international partners to jointly promote the globalization of fire safety standards. Whether projects are in China, India, or any high-risk industrial area, Tengxi will use its reliable technical system and professional spirit to build a solid line of defense protecting lives and assets.
