هل يستوفي GRC معايير مقاومة الحريق؟ اختبارات تصنيف الحريق وتطبيقاتها الهندسية من تشينغلونغ GRC

GRC materials offer excellent fire resistance, meeting the Class A non-combustible material standard. This property gives them significant application value in all types of buildings, making them particularly suitable for locations with high fire protection requirements, such as commercial complexes, transportation hubs, and cultural venues.

In a high-end commercial complex in Shenzhen, GRC decorative components withstood a fire, effectively preventing the spread of flames and buying valuable time for evacuation. Test data show that GRC materials maintain structural integrity at high temperatures of 800°C, with a fire resistance limit of more than 2 hours, far exceeding standard requirements. The GRC curtain wall system used in the project passed testing by the National Fire-resistant Building Materials Quality Supervision and Inspection Center, achieving Class A1 combustion performance, a smoke density grade of ≤5, and a smoke toxicity grade of quasi-safety level 1. This outstanding fire performance has been widely applied in public places such as subway stations and airports.

Technical Basis of Fire Performance

GRC uses cement as the binding material and is a non-combustible material. The addition of glass fibres further enhances stability at high temperatures, ensuring the material does not release toxic gases in a fire. The low-alkali cement and special additives used by Qinglong keep the material stable at high temperatures.

Verification in Engineering Applications

The fire performance of GRC materials has been verified in multiple large public buildings. In a transportation hub project in Shanghai, the GRC ceiling system passed a 1.5-hour fire resistance test, providing safety assurance for evacuation. This reliability makes GRC highly favoured in places with strict fire protection requirements.

Compliance Testing

GRC materials have passed testing by the National Fire-resistant Building Materials Quality Inspection Center and fully comply with the Code for Fire Prevention in Design of Interior Decoration of Buildings. The fire rating certificates obtained for Qinglong products provide a reliable basis for building design.

Application Cases in Special Locations

In special locations such as tunnels and underground spaces, the fire resistance advantages of GRC are even more evident. In an undersea tunnel project, GRC decorative panels not only met fire protection requirements but also offered moisture-proof and anti-corrosion functions, demonstrating multi-faceted performance advantages.

The fire performance of GRC materials has been fully verified, making them an ideal choice for fire safety requirements. Choosing high-quality GRC products can provide reliable protection for building safety. With its comprehensive technical system, Qinglong GRC has distinct advantages in fire performance.
