Does GRC Meet Fire Resistance Standards?

The fire performance of GRC is an important safety attribute as an architectural decorative material. According to the Chinese national standard "Classification for Burning Behavior of Building Materials and Products" (GB 8624), GRC, whose main components are cement and glass fiber, has a combustion performance rating of Class A and is classified as a non-combustible material. All GRC products produced by Qinglong Group comply with the Class A fire protection standard, which means they will not burn under fire conditions and will not produce toxic smoke, buying precious time for personnel evacuation and fire rescue.

The non-combustibility of GRC stems from its inorganic nature. Its main components are cement, sand, and glass fiber; these materials do not burn at high temperatures and only lose part of their bound water when exposed to excessive heat, without releasing combustible gases. Compared with many organic decorative materials (such as wood and plastic), GRC has inherent advantages in fire safety. In the interior and exterior decoration of high-rise buildings and large public buildings (such as theaters, convention and exhibition centers, and transportation hubs), using Class A fire-rated GRC materials is a reliable choice for meeting building fire codes and safeguarding life and property. Projects that Qinglong participated in, such as the Wuhan Han Show Theater and the Hainan International Convention and Exhibition Center, place extremely high demands on the fire rating of materials, and the Class A attributes of GRC were one of the key factors in its selection.

It should be emphasized that the fire performance of GRC is an attribute of the material itself. In actual projects, the fire performance of the entire decorative system (including GRC panels, connectors, insulation materials, etc.) must be considered as a whole. While providing GRC products, Qinglong ensures that the connectors used (such as metal anchors) also meet the corresponding fire resistance requirements, and provides scientific system construction recommendations to ensure the safety and integrity of the entire exterior envelope system in the event of a fire. Therefore, choosing code-compliant GRC products can provide a reliable fire barrier for buildings.
