What Are the Core Technical Indicators of Fireproof GRC Decorative Panels? Safety Assurance and Qinglong Group's Class A Fire Resistance Standard

The core technical indicators of fireproof GRC decorative panels are the statutory benchmark for measuring their building safety, and must be evaluated strictly in accordance with the national standard "Classification for Burning Behaviour of Building Materials and Products" (GB8624-2012). The core indicator is "Combustion Performance Grade A (A1)", and the panels must also pass a series of additional tests covering "heat of combustion, smoke density, smoke toxicity, and fire integrity". Fireproof GRC panels produced by Qinglong Group, tested by the National Quality Supervision and Inspection Center for Fixed Fire Extinguishing Systems and Fire-Resistant Building Components, fully meet the A1-class non-combustible material standard, with a total heat of combustion PCS≤2.0 MJ/kg and smoke toxicity reaching the quasi-safe ZA3 level. As a key component of the building exterior wall system, their construction has been professionally tested to achieve a fire resistance limit of over 1 hour. In large public buildings such as the Shenzhen Pingshan High-Tech Zone Comprehensive Service Center (a Luban Award project), Qinglong fireproof GRC decorative panels are one of the key materials for passing fire acceptance inspections and ensuring personnel safety. Fire performance is the inviolable lifeline of decorative materials.

Combustion Performance Grade A (A1) Is a Mandatory Threshold

According to GB8624-2012, the combustion performance of building materials is classified into four grades: A (non-combustible), B1 (flame-retardant), B2 (combustible), and B3 (easily combustible). Grade A is the highest grade, among which A1 is the most demanding. The raw materials of Qinglong GRC—cement, quartz sand, and alkali-resistant glass fiber—are all inorganic mineral materials, fundamentally eliminating any possibility of combustion, which is the inherent advantage behind its A1 certification. Every batch of products we supply comes with an authoritative test report to ensure the material itself is absolutely safe.

Additional Safety Indicators Must Not Be Overlooked

Beyond non-combustibility, secondary hazards during a fire must also be considered. In combustion tests, our GRC panels produce extremely little smoke (smoke density grade SDR≤15) with low smoke toxicity, creating favorable conditions for evacuation and firefighting rescue. Meanwhile, we strictly control raw materials to ensure they contain no halogens or other components that would produce toxic gases when burned.

System Fire-Resistant Construction and Integrity

As decorative panels, the fire performance of the overall system they form together with walls, furring, and other components is equally important. We provide nationally tested and certified fireproof GRC curtain wall system construction details, including key node designs such as inter-story fire stopping and cavity fire separation, ensuring that in the event of a fire the spread of flames and high-temperature smoke can be effectively blocked, meeting the requirements of the "Code for Fire Protection Design of Buildings" (GB50016) for exterior wall insulation and decoration systems.

Therefore, when choosing fireproof GRC panels, never rely solely on verbal promises; you must verify authoritative test reports bearing the CMA or CNAS mark. With a highly responsible attitude toward life and property, Qinglong Group builds a reliable fire barrier for its clients using the most stringent standards and the most transparent data.
