What Is the Spacing for GRC Installation? — Connection Point Design Specifications and Technical Key Points

GRC installation spacing design requires comprehensive consideration of panel dimensions, wind loads, and seismic action. Based on years of engineering practice, Qinglong Group believes the hanging point spacing of standard GRC panels should be controlled at 600-800mm, with the distance from panel edges to hanging points no less than 150mm, and appropriately densified at special locations. Through scientific calculation and optimized design, the installation system is ensured to be safe and reliable.

Panel dimensions are the primary factor in determining spacing. Standard panels (1.2m×2.4m) use four corner hanging points with evenly distributed spacing. Large panels (length >3m) add intermediate hanging points to avoid excessive deflection. In the Hainan project, Qinglong Group optimized the hanging point layout through finite element analysis, reducing the stress concentration factor to below 1.2. This scientific design ensures both safety and economic rationality.

Load conditions affect spacing design. In areas with high wind pressure, hanging points are appropriately densified to improve wind resistance. In seismic fortification zones, seismic requirements are considered, and spacing design allows a certain degree of deformation. Qinglong Group customizes solutions based on specific project conditions to ensure optimal installation spacing.
