How to Fix GRC After Installation? Qinglong GRC Installation and Fixing Technology Explained

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

In the curved curtain wall project of Wuhan Hanxiu Theater, Qinglong adopted a three-dimensionally adjustable dry-hanging system: channel-type embedded parts pre-embedded in the substrate, vertical 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 not only ensures installation precision but also accommodates 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-Fixing Method

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

Adhesive Bonding Process

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

Hybrid Fixing Solution

Multiple safeguards for critical areas. Adhesive bonding combined with mechanical fixing. Reinforced fixing in seismic fortification zones. Solutions must be verified by calculation.

The fixing system requires mechanical calculation to ensure safety. Qinglong GRC provides professional fixing solution design services.
