How to Secure GRC After Installation? A Detailed Guide to Qinglong GRC Installation Fixing Techniques

GRC installation and fixing require selecting the appropriate fixing method based on panel dimensions, installation location, and substrate type to ensure safety and reliability. Common fixing methods include dry-hanging, point-hanging, and adhesive bonding.

In the curved curtain wall project of the Wuhan Hanxiu Theater, Qinglong adopted a three-dimensionally adjustable dry-hanging system: channel-type embedded inserts in the substrate, vertically installed main keels, and horizontal secondary keels adjustable in three dimensions. GRC panels are connected to the keels via stainless steel hangers, which can be adjusted ±20mm front-to-back, ±15mm left-to-right, and ±10mm up-and-down. This flexible connection system ensures installation accuracy while accommodating structural deformation. After 5 years of service, the fixing system remains intact.

Dry-Hanging Fixing System

Suitable for exterior walls of high-rise buildings, safe and reliable. The keel system requires structural calculation. Hangers must be equipped with anti-detachment devices. The adjustment range should meet construction needs.

Point-Hanging Fixing Method

Suitable for interior walls, quick to install. Anchor pull-out resistance must meet standards. Fixed points on panel edges should be ≤100mm from the edge. Fixed points require concealed work acceptance.

Adhesive Bonding Fixing Process

Suitable for thin panel installation with flat surfaces. Bond strength ≥0.4MPa. The substrate requires interface treatment. Critical areas require additional mechanical fixing.

Hybrid Fixing Solution

Critical areas adopt multiple safeguards. Adhesive bonding combined with mechanical fixing. Reinforced fixing in seismic fortification zones. Solutions must be verified by calculation.

Fixing systems require mechanical calculation to ensure safety. Qinglong GRC provides professional fixing solution design services.
