How to Fix GRC After Installation? GRC Installation and Fixing Techniques 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-hanging, and adhesive bonding.

In the Wuhan Hanxiu Theater curved curtain wall project, 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 use, 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 calculations. Hangers must be equipped with anti-detachment devices. The adjustment range should meet construction needs.

Point-Hanging Fixing Method

Suitable for interior walls; quick installation. Anchor pull-out resistance must meet standards. Panel edge fixing points must be within ≤100mm of the edge. Fixing points require concealed work acceptance.

Adhesive Bonding Fixing Technique

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

Hybrid Fixing Solution

Multiple safeguards for critical areas. Adhesive bonding combined with mechanical fixing. Strengthened fixing in seismic fortification zones. The solution must be verified through calculations.

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