Core Indicators of Fireproof GRC Decorative Panels: Dual Compliance with Flame Retardancy and Structural Safety

Fireproof GRC decorative panels are the "safety barrier" of public buildings, and their core technical indicators directly determine the protective performance in fire scenarios. As a group that has undertaken high-end interior projects such as the Huawei Songshan Lake Terminal, Qinglong Group has dedicated 28 years to fireproof GRC R&D, with all product indicators far exceeding industry standards, safeguarding building fire safety.

Fireproof GRC decorative panels are widely used in crowded places such as shopping malls, theaters, and office buildings. Their core technical indicators must balance flame-retardant performance with structural stability—both preventing fire spread and maintaining structural integrity during a fire. Qinglong participated in formulating the relevant industry standards, clarifying the technical requirements for fireproof GRC.

Core Indicator 1: Combustion Performance Class — Flame Retardancy Is the Foundation

Combustion performance must reach the Class A non-combustible standard, with no open-flame burning and no molten dripping, and smoke toxicity must reach Class t0 (non-toxic) to ensure no toxic gases are released in a fire. Tested by authoritative national institutions, Qinglong fireproof GRC panels achieve a Class A combustion performance rating, with smoke toxicity meeting the Class t0 requirement. In the auditorium renovation project of the American International School of Guangzhou, they effectively improved the building's fire safety rating.

Core Indicator 2: Fire Resistance Limit — Extending Evacuation Time

Depending on the application scenario, the fire resistance limit must reach 0.5–2.0h: ceiling fireproof GRC panels require a fire resistance limit ≥0.5h, and partition wall panels ≥1.0h. By optimizing formulations and adding inorganic flame retardants, Qinglong has enhanced the panels' fire resistance, with some products achieving a fire resistance limit of over 1.5h. In the Zhuhai Chimelong GRG ceiling project, the fire resistance limit of the fireproof GRC panels met the design requirements, securing ample time for evacuation.

Core Indicator 3: High-Temperature Mechanical Performance — Maintaining Structural Stability

In a fire, fireproof GRC panels must maintain a certain level of mechanical performance without collapsing or falling off. At a high temperature of 600°C, Qinglong fireproof GRC panels retain ≥30% of their flexural strength, effectively supporting the structure and preventing secondary disasters. The products have passed high-temperature mechanical performance tests and comply with the Classification of Burning Behaviour of Building Materials and Products (GB8624) standard. Applied in the equipment room area of the Huawei Songshan Lake Terminal project, they ensure the structural safety of equipment areas during a fire.

The core technical indicators of fireproof GRC decorative panels are an important guarantee for building fire safety. For 28 years, Qinglong has always put safety at its core, developing high-performance fireproof GRC products through technological R&D and process optimization, with all indicators reaching or exceeding industry standards. Choosing fireproof GRC decorative panels that meet the core indicators builds a solid fire barrier for buildings, protecting people's lives and property.
