How to Secure GRC After Installation: Detailed Steps and Precautions Explained

[Qinglong GRC Technical Guide] Complete GRC Installation and Fixing Process: Professional Solutions from Detailed Design to Safety Acceptance

Precise Fixing: Dual Guarantee of Safety and Aesthetics for GRC Components

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its lightweight, high-strength, and flexible shaping characteristics, has become the preferred material for high-end projects such as grand theaters, commercial complexes, and landmark buildings. However, the technical control of the GRC installation and fixing stage directly affects building safety and the final presentation of the decorative effect. Qinglong Group, with 28 years of experience in GRC detailed design and construction, and in accordance with the requirements of the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), has summarized a systematic installation and fixing solution, helping designers and contractors achieve a perfect balance between safety and aesthetics.

I. Technical Preparation before GRC Installation and Fixing: Detailed Design as the Core

As a national high-tech enterprise, Qinglong always emphasizes "design first". Before GRC installation and fixing, three major technical preparations must be completed: first, BIM technology is used for component splitting and joint simulation to precisely locate anchoring points and ensure uniform load distribution on each GRC component; second, based on parameters such as the wind load and seismic intensity at the project site, the load-bearing capacity of the anchoring system is calculated, and stainless steel connectors that meet national standards are selected; finally, 3D scanning of the base structure is performed to generate an error analysis report, providing data support for on-site installation. This process fully demonstrates Qinglong's professional advantages in the field of GRC detailed design and is a key prerequisite for ensuring subsequent installation quality.

II. Core Steps of GRC Fixing and Installation: Standardized Operation and Precision Control

Qinglong's GRC installation and fixing adopts the "phased control method" to ensure the precise execution of each step. The first step is base treatment: remove floating dust and oil stains from the structural surface and use mechanical grinding to create a rough surface, enhancing the bond between GRC and the base; the second step is measurement and setting out: use a total station for spatial positioning, with errors controlled within ±2mm; the third step is connector installation: strictly fix the embedded parts in accordance with the detailed design drawings, ensuring that deviations in verticality and levelness do not exceed 1mm/m; the fourth step is GRC component hoisting: use special hoisting clamps to avoid damage caused by direct contact with the component surface; the fifth step is adjustment and fixing: fine-tune with 3D adjustment bolts to ensure flush component joints, with joint width controlled at 3-5mm, and finally fix the connectors with epoxy resin. This standardized process is the technical guarantee behind Qinglong's award-winning projects such as the Dongguan Women and Children's Activity Center.

III. Key Considerations for GRC Fixing Systems: Dual Consideration of Safety and Durability

During the GRC installation and fixing process, three core issues require special attention: first, material compatibility—Qinglong strictly requires that the thermal expansion coefficients of the connectors match those of the GRC components to avoid stress cracking caused by temperature changes; second, anti-corrosion treatment—all metal connectors adopt a dual anti-corrosion process of hot-dip galvanizing plus fluorocarbon spraying to ensure durability in humid environments; third, waterproof sealing—joints are filled with elastic sealant to form multiple waterproof barriers, effectively preventing rainwater penetration. In addition, Qinglong specifically reminds contractors that 100% tension testing must be carried out after installation, and the tensile load-bearing capacity of a single anchoring point should be ≥5kN—a standard far above the industry average.

IV. Full Lifecycle Guarantee: After-Sales Advantages of Qinglong's GRC Fixing System

As a GRC manufacturer integrating production, construction and installation, and after-sales maintenance, Qinglong has established a comprehensive full-process service system. After installation, a 5-year warranty service is provided, with regular on-site inspections and real-time monitoring of component status through the RFID chip traceability system. For different application scenarios, such as salt spray corrosion environments in coastal areas, customized protection solutions can also be provided. This "one-stop" service model is precisely an important reason why Qinglong has been able to establish long-term cooperation with well-known real estate groups such as Poly and China Overseas.

From detailed design to after-sales maintenance, every step of GRC installation and fixing requires the support of professional technology and accumulated experience. Building on 28 years of industry experience, Qinglong Group integrates the philosophy of "meticulousness and excellence" into every project, not only providing customers with safe and reliable GRC fixing solutions, but also driving industry standard upgrades through technological innovation. Choosing a professional GRC manufacturer is a wise choice to ensure both decorative effect and structural safety.
