What Are the Steps for GRC Installation and a Detailed Operation Guide

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become the ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings, thanks to its advantages of light weight, high strength, and flexible styling. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group fully understands the decisive role that standardized GRC installation procedures play in project quality. This article systematically breaks down the key steps of GRC installation and, drawing on Qinglong's integrated experience in detailed design, manufacturing, and on-site construction, provides designers and project owners with a professional operation guide, helping to create building envelopes that combine aesthetics with safety.

Preparation Before GRC Installation: From Drawing Refinement to Material Acceptance

The success of GRC installation begins with rigorous preliminary preparation. Before construction, the Qinglong team works with the design party to refine a three-dimensional parametric model, using BIM technology to simulate installation nodes and ensure that component dimensions precisely match the on-site structure — a step that is particularly critical for complex shapes such as double-curved surfaces and openwork patterns, effectively avoiding the errors of traditional two-dimensional drawings. Upon arrival on site, materials must undergo strict acceptance inspection in accordance with the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), with focus on component strength (flexural strength ≥ 15MPa), surface flatness, and embedded part positions; substandard products are firmly returned to the production base for rework. At the same time, the construction site must complete substrate treatment, including structural surface leveling, rust removal from embedded parts, and spatial surveying and layout. Qinglong's original "3D laser scanning positioning method" can control errors within ±2mm, laying a solid foundation for subsequent installation.

Core Installation Process: Standardized Operations from Anchoring to Joint Treatment

The core steps of GRC installation must follow the principle of "safety first, precision foremost." The "double-bolt seismic anchoring system" adopted by Qinglong is a mature solution validated by 58 patented technologies: custom steel brackets are first fixed to the main structure with chemical anchor bolts, and GRC components are then connected via stainless steel adjustment bolts, enabling three-dimensional fine adjustment (adjustable ±5mm along the X/Y/Z axes). The installation sequence strictly follows the "bottom to top, left to right" principle; each component requires temporary fixing and verticality correction, verified by both a straightedge and a total station. For oversized components (single pieces weighing over 500kg), Qinglong deploys dedicated lifting equipment and prepares contingency plans. Joint treatment is key to both aesthetics and waterproofing: elastic sealant filling (width ≥ 10mm) combined with PE rod backing ensures that sealing performance is maintained under temperature deformation and vibration loads — a technique that has withstood real-world tests in projects such as the Nanjing East Road Century Plaza renovation.

Quality Control and Post-Installation Maintenance: The Core Guarantee of Qinglong's Full-Chain Service

High-quality GRC projects depend on full-cycle quality control. During installation, Qinglong implements the "three-inspection system" (self-inspection, mutual inspection, and special inspection), with key monitoring of anchoring point pull-out force (≥ 5kN), joint flatness (≤ 3mm), and fire rating (meeting the Class A1 non-combustible standard). After installation, surface cleaning and protective treatment are carried out, using a special hydrophobic coating spray to enhance stain resistance and durability. As a national high-tech enterprise, Qinglong has established a comprehensive after-sales maintenance system, providing quality tracking services for up to 10 years, with regular inspections (twice a year) to promptly identify and resolve issues such as component displacement and sealant aging. This integrated service model of "detailed design - manufacturing - construction and installation - after-sales maintenance" is precisely the core competitiveness that enables Qinglong to undertake complex projects such as the Dongguan Women and Children's Activity Center and overseas landmark projects.

From preliminary technical disclosure to final completion acceptance, GRC installation is a comprehensive test of material performance, construction techniques, and project management. Backed by 28 years of industry experience, Qinglong Group carries its philosophy of "meticulousness and relentless pursuit of excellence" through every step, not only ensuring that installation quality meets national standards, but also achieving the perfect realization of design creativity through technological innovation. For project owners seeking the unity of architectural aesthetics and structural safety, choosing a GRC manufacturer with full-chain service capabilities is the key to maximizing project value — and this is also the founding aspiration of Qinglong, as a vice-chairman unit of the China GRC Association, in its ongoing commitment to advancing the standardized development of the industry.
