What Are the Requirements for Installing and Fixing Premium GRC Components

In the field of architectural decoration, GRC components, with their lightweight, high-strength, and versatile shaping characteristics, have become the ideal choice for numerous landmark buildings and high-end projects. However, the installation and fixing method of quality GRC components directly affects building safety and the durability of the decorative effect, which is also a core concern shared by designers, owners, and contractors. As an industry leader with 28 years of experience in detailed design, manufacturing, and construction of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze the key requirements for installing and fixing quality GRC components from a professional perspective, providing reliable technical references for project implementation.

### 1. Load-Bearing Structure Compatibility: The Safety Foundation for Fixing GRC Components
The installation and fixing of quality GRC components must first ensure the reliability of the load-bearing structure. According to the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), the installation substrate must meet the requirements of compressive strength ≥15MPa and flatness error ≤5mm/2m. During the detailed design stage, Qinglong uses BIM technology to simulate the load distribution of components. For different substrates such as concrete walls and steel structures, adapted solutions such as embedded part welding and chemical anchor fixing are adopted. For example, Grade 8.8 high-strength bolts are used on steel structure substrates to ensure a pull-out resistance of each anchor ≥15kN, eliminating structural safety hazards at the source.

### 2. Connection Node Design: The Key to Balancing Strength and Deformation
GRC is a brittle material, so connection nodes must balance load-bearing capacity with seismic deformation performance. Qinglong adopts a composite solution of “flexible connection + rigid fixing”: horizontally, adjustable stainless steel hangers are used, allowing ±5mm of horizontal displacement; vertically, elastic rubber pads are installed to absorb stress caused by thermal deformation. Taking the GRC exterior wall cladding panels of a commercial complex as an example, 3D scanning positioning technology achieved a hanger installation error ≤2mm; combined with basalt fiber-reinforced GRC components (flexural strength ≥22MPa), they successfully withstood the challenge of Force 12 wind pressure in typhoon-prone regions.

### 3. Anti-Corrosion and Anti-Rust Treatment: Ensuring Long-Term Durability
The fixing systems of outdoor GRC components must have excellent anti-corrosion performance. Qinglong applies hot-dip galvanizing to all metal connectors (zinc coating thickness ≥85μm) and applies polytetrafluoroethylene grease to bolted connections, effectively isolating moisture and chloride ion corrosion. For projects in humid regions or coastal areas, 316 stainless steel is further adopted, offering salt spray resistance of over 5,000 hours, far exceeding conventional industry standards. Thanks to this attention to detail, the fixing system of a seaside hotel project in Malaysia undertaken by Qinglong shows no signs of rust after 10 years of sea breeze corrosion.

### 4. Installation Process Standards: From Precision Control to Quality Traceability
The installation of quality GRC components must follow refined construction procedures. Qinglong has established a “Three-Inspection System” quality control framework: sampling tests of component load-bearing capacity before delivery (sampling ratio ≥5%), on-site positioning with total stations (axis deviation ≤3mm), and post-completion verification through drone-based 3D modeling. In addition, all fixing nodes are embedded with RFID chips to enable full lifecycle quality traceability. This rigorous craftsmanship was fully demonstrated in the Nanjing East Road Century Plaza renovation project, which adopted Qinglong UHPC translucent concrete components. Through modular installation technology, the jointing error of 300 special-shaped components was controlled within 1mm, winning the Silver Award of the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

### 5. Full-Chain Service Assurance: Closed-Loop Support from Design to Maintenance
The installation and fixing of quality GRC components is not an isolated step but an important part of full-chain services. Qinglong provides integrated services from detailed design and manufacturing to construction installation and after-sales maintenance: parametric design is used to optimize node structures in the early stage, automated production lines ensure component precision during production, certified professional installation teams are deployed during construction, and 5 years of free maintenance (including connector inspection and tightening) is provided afterwards. This full-chain advantage has enabled Qinglong to establish long-term cooperation with renowned real estate groups such as Poly and China Overseas, making it the designated GRC supplier for many major domestic projects.

As a national high-tech enterprise and a participant in formulating GRC industry standards, Qinglong always approaches every installation detail with an attitude of “meticulousness and excellence.” The installation and fixing of quality GRC components is not only a reflection of technical requirements but also a long-term commitment to building safety and aesthetic value. Going forward, Qinglong will continue to drive innovation in GRC installation technology, contributing professional strength to creating aesthetically beautiful architecture.
