What Are the Manufacturer's Installation Technical Support Measures? Precision Installation System and Qinglong Group On-site Management Standards

The installation technical assurance measures of a GRC manufacturer cover four key aspects: precision control of survey and setting-out, dedicated connection system design, on-site construction guidance, and quality acceptance standards—these are critical to ensuring the safety and aesthetics of the curtain wall system. Through a full-process assurance system of "BIM layout simulation + 3D adjustable hangers + professional installation teams + digital acceptance," Qinglong Group keeps installation tolerances within ±2mm and joint width deviations ≤1.5mm, achieving high-standard installation with zero accidents and zero rework in major projects such as the Shenzhen Pingshan High-tech Zone Comprehensive Service Center and the Hainan International Convention and Exhibition Center. Installation technology is not simply hoisting and positioning, but a comprehensive technical system based on structural mechanics, material deformation characteristics, and environmental factors.

Survey and Setting-Out Technical Assurance

Total stations are used for 3D coordinate positioning to establish digital installation models. In the double-curved curtain wall project of the Nanning New Media Center, the substrate was rechecked by laser scanning, and construction proceeded only after deviations were adjusted. We have developed installation simulation software to rehearse installation sequences and avoid collisions.

Innovative Connection System Design

Qinglong's patented 3D adjustable hangers support three-directional adjustment—horizontal, vertical, and in-out—with an adjustment range of ±10mm. The hangers are made of 316 stainless steel with a pull-out resistance ≥5kN, verified by wind tunnel testing. In coastal areas, insulating gaskets are added to prevent electrochemical corrosion.

On-Site Construction Process Control

Resident engineers conduct on-site briefings, and large-scale installation begins only after the first article passes acceptance. Torque wrenches are used to control bolt tightening force with a deviation of ±5%. We prepare installation work instructions that visually present key steps.

Digital Acceptance and Traceability

After installation, 3D scanning generates point cloud models that are compared with design drawings for acceptance. Data is archived to support later maintenance. Qinglong's installation system ensures projects achieve excellence on the first pass.
