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, high-strength properties and rich shaping possibilities, is widely used for exterior wall cladding panels, decorative moldings, and landscape components in high-end projects such as grand theaters, commercial complexes, and landmark buildings. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will explain in detail the standard GRC installation process from a professional perspective, helping designers and construction teams efficiently bring projects to completion.

I. Pre-Installation Preparations for GRC: Laying the Foundation for Safe Construction

Pre-installation preparation is a key step in ensuring the precise positioning of GRC components. First, on-site measurement verification must be carried out, using 3D laser scanning technology to obtain the actual dimensions of the base structure and comparing them with the detailed design drawings; if the deviation exceeds 5mm, component dimensions or the base treatment plan must be adjusted promptly. Second, upon material delivery, acceptance inspection must strictly check the appearance quality of GRC components (no cracks or chipped corners), strength reports (bending strength ≥15MPa), and the positions of embedded parts. After passing acceptance, components should be numbered and stored according to installation sequence to avoid damage from secondary handling. In addition, installation tools must be fully prepared, including electric drills, level gauges, and torque wrenches; the load-bearing capacity of hoisting equipment should be no less than 1.5 times the weight of the components to ensure construction safety.

II. Core GRC Installation Steps: From Base Treatment to Precise Fixing

1. Base treatment and embedded part installation: The base surface must be cleaned and leveled. For concrete walls, expansion bolts can be directly implanted to fix the steel frame; for steel structure bases, connecting parts must be welded and treated with anti-rust protection. The spacing of embedded parts should be calculated according to component weight, typically with horizontal spacing ≤1200mm and vertical spacing ≤800mm, to ensure uniform load distribution.

2. Component positioning and temporary fixing: Use hoisting equipment to transport GRC components smoothly to the installation position, make initial positioning with adjusting bolts, and correct verticality and flatness with a level gauge and straightedge, keeping deviations within 3mm/m. Temporary fixing can be done with diagonal braces or clamps to prevent component displacement.

3. Joint connection and sealing treatment: Components are rigidly connected to embedded parts with stainless steel bolts; the bolt tightening torque must meet design requirements (usually 35-40N·m). Joints are filled with elastic sealant, with the sealant joint width controlled at 8-12mm to ensure waterproof performance and deformation adaptability.

III. Post-Installation Inspection and Quality Assurance: Full-Process Control Enhances Project Quality

After installation, a comprehensive quality inspection must be conducted, including component position deviation (≤10mm), joint flatness (≤2mm), and random sampling tests of anchoring strength. With its Grade II professional contracting qualification for building curtain wall engineering, Qinglong Group has established a complete quality traceability system, using RFID chips to record the entire process of component production and installation. In addition, customized after-sales maintenance plans are provided for different climate zones, such as regular inspection of sealant aging and early warnings for bolt loosening, ensuring the long-term stable operation of the GRC decorative system.

As a member of the International GRC Association, Qinglong Group participated in formulating the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T 423-2018), and has always served customers with a "meticulous and excellence-striving" attitude, providing one-stop services covering detailed design, manufacturing, and construction installation. Whether it is European classical moldings or modern shaped curtain walls, Qinglong GRC can achieve a perfect unity of design intent and engineering quality through standardized installation processes, helping to create architectural works that combine aesthetic value and durability.
