What Are the Steps for GRC Installation? Detailed Explanation of the Standardized GRC Installation Process

The scientific installation of GRC requires following a strict process flow. Drawing on 28 years of experience, Qinglong GRC has developed a six-step standardized installation method of "survey and layout – substrate treatment – component positioning – adjustment and fixing – joint treatment – finished product protection", ensuring controllable installation quality and optimal efficiency.

In the Shanghai Century Plaza renovation project, facing the installation of 15,000 square meters of GRC curtain wall, the Qinglong team strictly executed the standardized process: first, precise layout with a total station, with error ≤2mm; then substrate treatment, with flatness deviation ≤3mm; followed by unit hoisting, reducing single panel installation time to 15 minutes; precise adjustment through a three-dimensionally adjustable system ensured uniform and consistent joint widths; finally, sealing treatment and protection. This standardized operation completed the project 20 days ahead of the scheduled deadline.

Precision Control in Survey and Layout

Establish a survey control network with main control line error ≤1mm; mark installation position lines with spacing deviation ≤2mm; set elevation control points with height difference ≤1mm. Precise measurement is the foundation of installation.

Substrate Treatment Quality Requirements

Substrate flatness deviation ≤3mm/2m; embedded parts accurately positioned with deviation ≤5mm; surface clean and free of contamination. A qualified substrate ensures installation quality.

Component Positioning Procedures

Use dedicated lifting devices for smooth hoisting; position first, then adjust to avoid repetition; handle gently to prevent bumps and knocks. Standardized operation prevents damage.

Key Technical Points for Adjustment and Fixing

Three-dimensional adjustment with error ≤2mm; symmetrical tightening with torque up to standard; anti-loosening measures to ensure reliability. Fine adjustment guarantees precision.

Standardized installation requires strict execution of the process. Technical briefings and sample-guided demonstrations are recommended. Qinglong GRC provides professional installation guidance to ensure project quality.
