What Are the Steps of GRC Installation? Detailed Explanation of Qinglong's Standardized GRC Installation Process

GRC installation must follow a standardized process, generally divided into six stages: preparation, measurement and layout, substrate treatment, panel installation, joint treatment, and cleaning and acceptance. Each stage has strict technical requirements.

In the Shanghai Century Plaza renovation project, the Qinglong installation team strictly implemented the standardized process: first, a site survey was conducted using a 3D scanner to obtain substrate data; then a BIM model was used for installation simulation to optimize the installation sequence; during installation, a bottom-to-top, center-first-then-sides sequence was adopted, with a fixed area completed each day; joint treatment used specialized sealant applied in two passes; finally, comprehensive inspection and acceptance were carried out. This standardized operation ensured the project was completed to a high standard.

Pre-Installation Preparation Stage

Verify drawings against on-site dimensions; adjustments are required if errors exceed tolerances. Check panel numbering, quantity, and quality; replace damaged panels. Prepare construction tools and check safety devices. Technical briefings clarify key points.

Measurement and Layout Stage

Set installation datum lines with an accuracy of ±1mm. Mark panel grid lines clearly and accurately. Recheck substrate dimensions and record deviation data. Layout lines must be verified and confirmed after marking.

Substrate Treatment Requirements

Substrate strength must meet standards, free of hollowing and cracks. Flatness deviation ≤4mm/2m. Waterproofing layer intact, with no leakage. Embedded parts accurately positioned, firm and reliable.

Panel Installation Technique

Install panels in numbered sequence to prevent mix-ups. Install hangers firmly and adjust into position. Keep panel joints even with consistent width. Inspect and correct promptly to ensure quality.

Strict adherence to the standard process is the guarantee of installation quality. Qinglong GRC's standardized installation system ensures every project is perfectly presented.
