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

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its lightweight, high-strength, and flexible-forming characteristics, 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 effect and structural safety. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP, Qinglong Group has summarized a standardized installation process based on more than a thousand engineering projects, providing designers and owners with a practical technical guide.

Preparation Before GRC Installation: From Drawing Refinement to Material Acceptance

Professional GRC installation begins with precise preliminary planning. First, the BIM model refinement must be completed, with anchoring points located based on structural data to ensure that the connection strength between components and the main structure complies with the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings (JGJ/T423-2018). When materials arrive on site, the factory certificates of Qinglong GRC components must be verified, with key indicators such as surface flatness (tolerance ≤2mm/m), glass fiber content (≥4%), and flexural strength (≥15MPa) carefully checked to prevent material defects from compromising installation quality.

Core Installation Process: From Base Treatment to Fine Adjustment

Base treatment is the foundation of installation: the structural surface must be cleared of debris and leveled, with a special interface agent applied to enhance the adhesion between GRC and the base. Next, measurement and setting-out are carried out, using 3D laser scanning technology to achieve millimeter-level positioning and ensure the assembly precision of complex-shaped components. The installation stage follows the principle of "primary first, secondary later, layer-by-layer installation," with components fixed by stainless steel embedded parts and expansion bolts; the pull-out resistance of each anchor should be ≥10kN. Qinglong's original modular installation process can reduce on-site assembly time by 30%, making it especially suitable for complex projects such as curved curtain walls.

Quality Control and Safety Assurance: Details Determine Success

During installation, the three-stage inspection system must be strictly implemented: self-inspection focuses on joint gaps (≤5mm) and verticality (deviation ≤3mm/2m); cross-inspection pays attention to the anti-corrosion treatment of anchoring nodes; and special inspection verifies connection safety through tensile testing. For work at height, Qinglong deploys professionally certified installation teams equipped with dual-lanyard safety belts and fall arresters, while simultaneously implementing warning measures in the construction area. It is worth noting that GRC components must rest for 72 hours after installation, and sealant application should only proceed after the structural adhesive has fully cured, to prevent rainwater penetration from causing corrosion of the internal steel structure.

Qinglong's Full-Chain Service: A Reliable Choice from Design to Maintenance

As a National High-Tech Enterprise, Qinglong not only provides standardized installation guidance but also offers customized solutions tailored to project requirements. From parametric modeling in the preliminary detailed design stage, to automated assembly-line processing in production, and to full-process technical supervision during on-site installation, a closed-loop service of "design-production-installation-maintenance" is formed. For example, in a cultural landmark project in Nanjing, Qinglong used BIM technology to simulate the installation process and successfully achieved seamless splicing of a double-curved GRC curtain wall, winning the inaugural UHPC Construction Engineering Innovation Award.

GRC installation is a combination of technology and experience, and choosing a supplier with full-chain service capability is crucial. With 28 years of dedication to the UHPC/GRC/GRG/GRP fields, Qinglong Group has provided safe and reliable decoration solutions for more than a thousand projects worldwide under the philosophy of "meticulousness and the constant pursuit of excellence." Whether it is European classical moldings or modern irregular curtain walls, Qinglong can transform design drawings into fine works of architectural art through standardized installation processes and customized technical support.
