What Are the Core Technical Indicators of Fire-Rated GRC Decorative Panels? Qinglong GRC Fire Performance Technical Standards

The core technical indicators of fire-resistant GRC decorative panels include four key parameters: combustion performance grade, fire resistance limit, heat release rate, and smoke density grade. According to the national standard GB 8624-2012, high-quality fire-resistant GRC panels should meet the Class A (A1) non-combustible material standard, with a fire resistance limit of ≥2 hours, a peak heat release rate of ≤200kW/㎡, and a smoke density grade of ≤15. These indicators ensure that the material does not burn and produces no toxic smoke in the event of a fire, providing valuable time for personnel evacuation.

Qinglong GRC fire-resistant panels have passed testing by the National Quality Supervision and Inspection Center of Fireproof Building Materials, achieving Class A (A1) combustion performance—they do not burn when exposed to fire and produce no toxic gases. In standard fire resistance tests, 15mm-thick GRC panels achieved a fire resistance limit of 2.5 hours, with a temperature rise on the non-fire side of ≤140℃ and integrity fully maintained. A commercial complex project using these fire-resistant GRC panels passed the fire safety acceptance inspection, providing reliable protection for building safety.

Combustion Performance Grade Requirements

Must reach Class A (A1) non-combustible material; combustion heat value ≤2MJ/kg; these are the fundamental requirements for fire safety.

Fire Resistance Limit Standards

Fire resistance limit ≥2 hours at a panel thickness of 15mm; temperature rise on the non-fire side ≤140℃; these standards guarantee structural fire resistance time.

Smoke Toxicity Control

Smoke density grade ≤15; smoke toxicity reaching quasi-safe grade ZA1; these controls reduce secondary hazards.

Integrity Retention Capability

No cracking or penetration during fire resistance tests; these capabilities prevent flame spread.

Fire performance is an important safeguard for life safety. Qinglong GRC fire-resistant panels strictly meet the standards—safe and reliable.
