GRC Installation and Fixing Technology: Multiple Safeguards for a Solid Safety Line

The installation and fixing of GRC (Glass Fiber Reinforced Concrete) is the core factor determining its safety in use and service life. Only by adopting scientific fixing techniques and reliable fixing methods can the long-term stability of GRC components be ensured. Qinglong Group has been deeply engaged in GRC construction and installation for 28 years, developing and applying a variety of efficient and safe GRC installation and fixing technologies, building a solid safety line for thousands of projects.

The core principles of GRC installation and fixing are "uniform load distribution, secure connection, and environmental adaptability". The appropriate fixing method must be selected according to factors such as component type, installation location, and building structure. As a Grade II professional contractor for building curtain wall engineering, Qinglong always holds the fixing process to high standards. Combined with its own patented technologies, it has formed a comprehensive fixing technology system to ensure that every GRC component is installed securely.

???? Four Core Technologies of GRC Installation and Fixing and Their Application Scenarios

Dry-hanging Fixing Technology: The mainstream and efficient choice. Dry-hanging fixing is the most commonly used method in GRC installation. It connects GRC components to the building structure through hangers, requiring no on-site wet work and offering high construction efficiency. The stainless steel hangers used by Qinglong are high-strength and corrosion-resistant, and are secured to the base structure with chemical anchors or embedded parts to ensure firm connections. In the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, the GRC curtain wall adopted dry-hanging fixing technology with precisely controlled hanger spacing, achieving the stable installation of a 30,000-square-meter curtain wall and winning Luban Award recognition. Dry-hanging fixing is suitable for most GRC panels, moldings, and similar components, and is especially ideal for large public buildings and commercial complexes.

Bracket Fixing Technology: Suitable for complex components. For complex GRC components such as double-curved, oversized, or overweight ones, conventional dry-hanging fixing can hardly meet the load-bearing requirements, so customized bracket fixing technology is required. Qinglong designs customized steel brackets through BIM, first fixing the brackets to the building structure and then firmly connecting the GRC components to the brackets to ensure uniform load distribution. The double-curved GRC exterior wall panels of the Guangxi New Media Center, using customized bracket fixing technology, perfectly solved the fixing challenge of special-shaped components and achieved the precise realization of complex shapes. Bracket fixing technology is also suitable for the renovation of existing buildings and scenarios where the base structure is not suitable for direct dry-hanging.

Wet-adhesion Fixing Technology: Suitable for lightweight components and indoor scenarios. Wet-adhesion fixing bonds GRC components to the base with adhesive, and is suitable for lighter and smaller GRC components such as interior decorative moldings and small reliefs. Qinglong uses a dedicated GRC adhesive with high bonding strength and good weather resistance, combined with base treatment processes, to ensure firm adhesion. In the auditorium renovation project of the American International School of Guangzhou, the interior GRC decorative components adopted wet-adhesion fixing technology, which is easy to install and highly aesthetic without affecting the interior space effect. Wet-adhesion fixing requires attention to the flatness of the base and the even application of the adhesive to avoid hollowing.

Combined Fixing Technology: Enhanced safety redundancy. For key projects with extremely high safety requirements, Qinglong adopts combined fixing technologies such as dry-hanging + brackets or wet-adhesion + hangers to form a double safety guarantee. In the GRC component installation for the Hainan Changying Global 100 Fantasy Park, a combined fixing method of brackets + hangers was adopted, which ensured component stability while enhancing resistance to external forces. Combined fixing technology is suitable for GRC installation projects of large landmark buildings, high wind pressure areas, or important public buildings.

The choice of GRC installation and fixing technology requires comprehensive judgment based on actual project conditions, and a professional technical team with rich practical experience is the key. Qinglong Group not only possesses a variety of advanced fixing technologies, but has also cultivated a professional construction team familiar with all types of fixing methods, capable of selecting the optimal fixing solution according to component characteristics and installation environments. From hanger selection to bracket customization, and from adhesive selection to on-site construction, Qinglong always controls every detail with a rigorous attitude to ensure safe and reliable GRC installation and fixing. Choosing Qinglong means choosing long-term safety assurance for your GRC project starting from the fixing stage.
