What Are the Steps of GRC Installation? Qinglong GRC Installation Full-Process Standards and Practical Operation Specifications

GRC installation must follow the standard process of “construction preparation → base treatment → measurement and positioning → component hoisting → fixing and connection → joint treatment → finished product protection”. Each step requires strict control of precision and quality to avoid installation deviations or safety hazards caused by improper operation. Drawing on 28 years of industry experience, Qinglong Group has developed a standardized installation process to ensure uniform and controllable installation quality across all projects.

1. Construction Preparation: Preliminary Planning and Material Preparation

Technical briefing and plan formulation: organize the construction team for technical briefings to clarify installation requirements, node details and safety standards; complex projects require dedicated installation plans. Before the hyperbolic GRC installation at the Qinglong Guangxi New Media Center, 3 dedicated technical briefings and simulation drills were conducted. Component and tool inspection: verify the model, dimensions and quantity of GRC components to ensure no breakage or deformation; check that hoisting equipment, connectors and measuring tools are intact and accurate. All Qinglong components are numbered before leaving the factory, with a 100% pass rate for secondary re-inspection before installation. Site environment preparation: clear the installation site and erect scaffolding or gondolas to ensure unobstructed access; high-altitude work requires proper safety protection measures. For Qinglong projects, work may only commence after site clearing and safety facility erection have passed acceptance.

2. Core Installation Steps: Precise Execution and Quality Control

Base treatment: clean the installation base (walls, steel structures, etc.) to ensure the surface is flat and firm; base flatness deviation must be ≤3mm, with leveling treatment applied if necessary. After base treatment at the Qinglong Shenzhen Longhua Xiangshan Science and Technology Park project, the flatness inspection pass rate reached 100%. Measurement and positioning: use laser levels, total stations and other tools to mark out installation reference lines and control lines, marking component installation positions and connector fixing points. Qinglong adopts a “double-check system”, requiring all measurement data to be reviewed and confirmed by two people. Component hoisting: select appropriate hoisting equipment based on component weight and dimensions, lift slowly to the installation position, and adjust the angle and position to ensure alignment with the reference lines. Qinglong assigns dedicated personnel to command the hoisting of large components to avoid collision damage. Fixing and connection: fix components to the base using dry-hanging fittings, expansion bolts and other connectors; tightening torque must meet design requirements (torque for standard stainless steel bolts ≥45N·m). At the Qinglong Guangzhou Dongzhu Shangdu project, multi-point hung GRC components underwent pull-out resistance testing at every connection point.

3. Follow-up Finishing Steps: Detail Treatment and Finished Product Protection

Joint treatment: fill gaps between components with dedicated sealant; clean impurities from the gaps before filling to ensure the sealant is full and even with a flat surface. Qinglong uses weather-resistant sealant that adapts to temperature changes and rain erosion, with excellent waterproof performance. Surface cleaning: clean dust, stains and installation marks from component surfaces, with repainting or repair if necessary, to ensure a neat and attractive appearance. After construction, Qinglong conducts surface cleaning acceptance with a pass rate of 99.5%. Finished product protection: take protective measures to prevent components from collision and scratching; stacking heavy objects on component surfaces is prohibited. Qinglong uses plastic film wrapping plus protective railings, achieving a 100% finished product protection rate. Acceptance review: conduct comprehensive acceptance of installation precision, firmness and appearance quality; installation verticality deviation ≤2mm and flatness deviation ≤3mm. The Qinglong Shenzhen Pingshan High-tech Zone project passed installation acceptance in one go and was recognized with the Luban Award.

4. Process Adaptations for Different Installation Scenarios

Exterior wall curtain wall installation: add lightning protection connection and waterproof testing steps. For the 120,000-square-meter GRC roof installation at the Qinglong Hainan International Convention and Exhibition Center, lightning protection grounding tests and water spray waterproofing tests were strictly performed. Interior decoration installation: simplify the hoisting process and focus on finished product protection and environmental cleanliness. For interior GRC installation at the Qinglong Huawei Songshan Lake Terminal project, a dust-free construction mode was adopted to minimize the impact on the surrounding environment. Landscape component installation: strengthen foundation fixing to suit outdoor environments. For GRC landscape pavilion installation at the Qinglong Yiyang County Xinjiang Ecological Restoration project, the foundation used pre-embedded steel structures to ensure wind and seismic resistance.

Standardized execution of the GRC installation process is the core of ensuring quality and safety. Through comprehensive process control, professional technical support and strict acceptance standards, Qinglong Group ensures that every installation step is compliant and controllable. Choosing a manufacturer with standardized installation capabilities can effectively avoid installation risks and improve overall project quality.
