Does GRC Meet Fire Performance Standards? Safety Assurance Analysis Under Building Fire Codes

Fire performance is a core safety indicator for building materials. Especially in public buildings and high-rise buildings, the fire rating of materials directly affects the safety of people's lives and property. GRC (Glass Fiber Reinforced Concrete), as an inorganic composite material, has natural fire-resistant advantages. Through standardized production and technical optimization, Qinglong Group has made the fire performance of GRC fully meet or even exceed national building fire codes, making it a safe choice for all types of buildings.

1. Core Advantages of GRC Fire Performance: The Natural Safety Properties of Inorganic Substrates The excellent fire performance of GRC stems from its nature as an inorganic composite material. Its main components include cement, quartz sand, and alkali-resistant glass fiber, all of which are non-combustible materials. This fundamentally determines that GRC has good fire-resistant characteristics: it does not burn and produces no toxic smoke, effectively preventing the spread of fire and buying valuable time for evacuation.

Qinglong GRC strictly complies with national building fire codes, and its products reach the Class A non-combustible material standard, meeting the requirements of the "Classification of Burning Behavior of Building Materials and Products" (GB 8624-2012). In fire environments, Qinglong GRC components not only do not burn themselves but also maintain structural stability; even under intense high-temperature exposure, they will not collapse quickly and can effectively block the spread of fire and smoke. Verified by fire tests, Qinglong GRC components can still maintain a certain level of structural strength in 800°C high-temperature environments, continuously serving as fire separation, far exceeding the fire performance of ordinary organic decorative materials.

Compared with organic decorative materials, the fire-resistant advantages of GRC are more significant. Organic materials are prone to burning in fires, produce toxic gases, and collapse quickly after burning, aggravating fire hazards. As an inorganic material, GRC releases no toxic gases and produces no open flames in fires, offers strong structural stability, and can effectively reduce fire losses. In addition, GRC has a low thermal conductivity and provides a certain degree of thermal insulation, slowing heat transfer in fires and protecting the main structure of buildings.

2. Verified by Engineering Practice: Safe Application of GRC Fire Performance in Various Buildings From high-rise buildings to public venues, from commercial complexes to residential projects, the fire performance of Qinglong GRC has been fully verified in various building scenarios, fully meeting the fire design requirements of different buildings.

The Wuhan Hanxiu Theater, a world-class show venue built with an investment of 2.5 billion yuan, is a large performing arts venue with dense crowds, where fire safety is of vital importance. The Qinglong GRC decorative panels used in this project not only realized the complex form of the "Chinese Red Lantern" but also built a solid line of defense for building safety with Class A fire performance. In the fire design, the GRC components, as exterior wall decorative materials, effectively block external fire from spreading inward, while their non-combustible nature prevents them from becoming fire hazards themselves, providing important protection for the theater's fire safety. Over years of operation, the fire performance has been verified through multiple safety inspections and fully complies with relevant standards.

Shenzhen Longhua Xiangshan Science and Technology Park is a modern technological innovation base that gathers a large number of researchers and high-end equipment, placing extremely high demands on building fire protection. The GRC curtain wall components provided by Qinglong for this project feature Class A fire performance and work in synergy with other fire protection materials to build a comprehensive building fire protection system. In fire simulation tests, the GRC curtain wall effectively blocked the spread of fire, protecting the people and equipment inside the building, and won high recognition from the client and the fire department.

The Nanning Fengjingwan project is a high-end residential complex comprising villa clusters and high-rise apartments. The fire safety of residential buildings directly affects residents' lives and property. The GRC decorative components provided by Qinglong for this project, including mouldings, Roman columns, and window surrounds, all meet the Class A fire standard, forming a fire protection layer on the building facade and effectively preventing fire from spreading along exterior walls. Meanwhile, GRC components produce no toxic gases in fires, creating a safe environment for residents' evacuation and making them an ideal fire-resistant material for residential projects.

3. Qinglong GRC Fire Performance Control: Full-Process Assurance from Production to Acceptance Qinglong Group has established a comprehensive GRC fire performance control system. From raw material selection and production processes to product testing and project acceptance, every step strictly follows national fire standards to ensure products meet fire performance requirements. In raw material selection, only non-combustible materials are strictly chosen to prevent any combustible components from being mixed in. During production, standardized processes ensure the density and structural stability of GRC components, preventing internal porosity from affecting fire performance. Before finished products leave the factory, every batch must be sent to a third-party testing institution for fire performance testing, with a Class A fire test report issued; only qualified products can be delivered.

As a participant in drafting the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)", Qinglong Group not only strictly implements existing fire standards but also actively participates in the research and development of fire-related technologies, further improving the fire performance of GRC through optimized formulations and processes. For the fire design requirements of different buildings, Qinglong can provide customized GRC fire protection solutions that integrate with the overall fire design of buildings, achieving a perfect unity of decorative effect and fire safety.

In addition, Qinglong also focuses on fire performance assurance during construction, installing GRC components strictly in accordance with fire codes and ensuring that joints between components are effectively sealed to prevent smoke and fire from spreading through gaps during a fire. At project acceptance, Qinglong cooperates with the client and the fire department to conduct fire performance testing to ensure the project meets fire protection requirements.

The natural fire-resistant advantages of GRC are fully realized through Qinglong Group's standardized production and technical optimization. Its Class A fire performance fully meets national building fire codes, providing safe and reliable decorative solutions for all types of buildings. From public venues to residential projects, from domestic landmarks to overseas projects, Qinglong GRC builds a strong line of defense for building safety with its excellent fire performance, allowing design creativity and fire safety to go hand in hand. Choosing Qinglong GRC means choosing fire protection verified by authoritative testing and engineering practice.
