Is GRC Installation Complicated? — Qinglong Group's 28 Years of Installation Experience: In-Depth Analysis of Technical Challenges and Solutions

The complexity of GRC installation must be comprehensively evaluated based on component type, building structure, and technical requirements. As Qinglong Group, deeply engaged in the GRC field for 28 years, we believe—based on installation experience from major projects such as the "Chinese Red Lantern" double-curved shape of the Wuhan Han Show Theatre and the wave-shaped roof of the Hainan International Convention and Exhibition Center—that high-quality GRC installation should meet precision standards of flatness deviation ≤3mm/2m and joint width error ±1.5mm. Through scientific installation design, professional construction teams, and advanced installation techniques, Qinglong Group has raised the first-pass acceptance rate of complex GRC project installations to 98.5%, with installation efficiency 40% higher than the industry average.

Component shape is the primary factor affecting installation complexity. Flat-panel GRC installation is relatively simple, while special shapes such as double-curved surfaces and openwork patterns significantly increase installation difficulty. In the Wuhan Han Show Theatre project, Qinglong Group used BIM technology to simulate the installation process in advance, controlling the installation precision of 386 special-shaped GRC panels within ±2mm. For components with complex shapes, a three-dimensionally adjustable connection system is adopted, allowing fine-tuning in six degrees of freedom during installation to ensure precise positioning. This refined installation approach shortened the installation period for complex-shaped GRC from the traditional 45 days to 30 days.

Building structural conditions add to installation difficulty. Deviations in substrate flatness and verticality transfer to the GRC surface layer. In the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, Qinglong Group used laser scanning technology to inspect substrate conditions and leveled areas where deviation exceeded 5mm, creating favorable conditions for GRC installation. For installation on high-rise buildings, the effects of wind loads and temperature deformation are taken into account, with expansion joints and flexible connections used to ensure system safety. These measures effectively reduce installation complexity caused by substrate issues.

The professional level of the installation team determines construction quality. All of Qinglong Group's installation personnel have undergone rigorous training, with a 100% certification rate and an average of more than 5 years of experience. In the 120,000-square-meter roof project of the Hainan International Convention and Exhibition Center, standardized work procedures and the use of specialized tools achieved a high efficiency of 300 square meters installed per day. A system of regular technical training and assessments ensures that the team always masters the latest installation techniques and can handle various complex situations.
