What Are the Steps of GRC Installation? Detailed Analysis and Operation Guide

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its lightweight yet high-strength properties and flexible formability, has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings. However, the professionalism of GRC installation directly affects the final visual outcome and engineering quality. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will systematically break down the standardized steps of GRC installation, providing designers and owners with a construction guide that combines safety and aesthetic value.

I. Preliminary Preparation: Laying the Technical Foundation for GRC Installation

Successful GRC installation begins with rigorous preliminary planning. First, a detailed design review is required, combining architectural drawings with on-site measured data and using BIM technology to simulate the installation process to ensure precise alignment between GRC components and the main structure. In the Dongguan Women and Children's Activity Center project, Qinglong Group used 3D laser scanning technology to control tolerances within ±2mm, laying the foundation for subsequent installation. Next is material entry inspection, focusing on verifying the flexural strength of GRC components (which must exceed 20MPa), surface flatness, and embedded part positions, while also confirming Qinglong GRC's proprietary weather resistance test reports to ensure materials comply with the requirements of the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018).

II. Substrate Treatment: Building a Safe and Stable Installation Base

Substrate treatment is a key step in ensuring the long-term stability of GRC. Before construction, dust and oil stains on the surface of the main structure must be removed, concrete defects repaired, and a specialized bonding agent applied to enhance substrate adhesion. For high-altitude installation scenarios, Qinglong GRC uses a customized steel bracket system connected to the main structure via expansion bolts, with bracket spacing strictly controlled at 800-1200mm to ensure even load distribution. In the Nanjing Road Century Plaza renovation project, this technique effectively solved the load-bearing challenge of large-span translucent GRC components, achieving a unity of aesthetics and structural safety.

III. Precise Installation: Achieving Millimeter-Level Realization of Design Concepts

The core of GRC installation lies in precision control. Using a "bottom-to-top, center-to-both-sides" installation sequence, the verticality and flatness of components are adjusted with temporary fixing devices, with tolerances kept within 3mm/m. Qinglong Group's proprietary "3D positioning + modular splicing" technology increased the installation efficiency of over 2,000 specially shaped GRC exterior wall panels by 40% in a commercial complex project in Guangzhou. During installation, special attention must be paid to joint treatment: elastic sealant should be used for filling, with 5-8mm expansion joints reserved to prevent cracking caused by thermal deformation.

IV. Quality Acceptance and Maintenance: Quality Assurance Across the Full Life Cycle

After installation is complete, multi-dimensional quality acceptance must be carried out, including anchor point pull-out tests (tensile strength ≥15kN), surface flatness inspection, and water spray tests. Qinglong Group has established a comprehensive after-sales maintenance system, providing 5 years of regular inspection services, tracing component information via RFID chips, and promptly addressing potential hazards. Notably, GRC maintenance should avoid the use of strong acid or alkali cleaners; neutral detergent with a soft cloth is recommended to preserve its decorative effect and durability.

As a national high-tech enterprise and a participant in GRC standard development, Qinglong Group has always upheld a meticulous, excellence-driven attitude, integrating 28 years of engineering experience into every detail of GRC installation. From detailed design to after-sales maintenance, Qinglong's full-chain GRC service not only ensures the safety and beauty of projects but also drives industry standard upgrades through technological innovation. Choosing Qinglong means choosing a GRC solution that combines professional depth with practical experience, allowing every architectural concept to be realized with precision.
