What Technical Documents Are Needed for Custom GRC Components

In the field of architectural decoration, GRC components have become the ideal choice for many high-end projects thanks to their lightweight high strength and rich styling. However, customizing GRC components is a systematic project, and the completeness of technical documentation directly affects the quality and delivery efficiency of the final product. As an industry leader with 28 years of experience in detailed design, manufacturing, and production of UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze, from a professional perspective, the core technical documentation required for custom GRC components, helping projects advance efficiently.

1. Basic Design Drawings: The "Skeleton" of Custom GRC Components

The first step in customizing GRC components is to provide clear basic design drawings, which serve as the basis for subsequent detailed design and production. The drawings must include key information such as the plan dimensions, facade styling, and sectional structure of the components. If complex curved surfaces or special-shaped structures are involved, 3D model files (e.g., in Rhino or SketchUp format) must also be provided. Take the double-curved GRC cladding panels on the exterior wall of a grand theater as an example: an accurate 3D model helps the manufacturer accurately understand the design intent and avoid production errors caused by misreading 2D drawings. Qinglong Group recommends that designers mark key dimensional tolerances in the drawings—for example, the curvature error of curved surfaces should be controlled within ±3mm—to ensure a perfect fit between the components and the overall building.

2. Material Performance Parameters: Ensuring the "Intrinsic Quality" of GRC Components

The performance of GRC components depends directly on the material mix ratio and process control, so the material performance parameter requirements must be clearly specified. Core parameters include glass fiber content (usually no less than 4%), flexural strength (standard value ≥12MPa), compressive strength (standard value ≥40MPa), elastic modulus, and weather resistance indicators (e.g., ≥200 freeze-thaw cycles). In addition, depending on the project's application scenario, the fire resistance rating (generally required to reach Class A non-combustible) and surface treatment methods (e.g., stone-like texture, paint finish) must also be specified. As a national-level high-tech enterprise, Qinglong Group can provide customized material solutions according to project needs—for example, for projects in coastal areas, adjusting the mix ratio to improve the salt spray resistance of GRC components.

3. Installation Node Details: Ensuring the "Safe Implementation" of GRC Components

Installation node design is key to the safe use of GRC components, and detailed anchoring methods, connection node details, and load calculation documents must be provided. Node design should take into account factors such as wind loads, seismic loads, and temperature deformation. For example, GRC cladding panels on the exterior walls of high-rise buildings require flexible connections that allow a certain amount of displacement. During the detailed design phase, Qinglong Group uses BIM technology for node simulation to ensure that anchoring strength complies with the "Technical Standard for Building Applications of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018), and provides installation guides and on-site technical support to ensure construction safety.

4. Project-Specific Requirements: The "Personalized Label" of Custom GRC Components

Different projects have individualized requirements for GRC components, which must be clearly stated in the technical documentation. For example, GRC components for landmark buildings may require special surface textures or artistic effects, in which case texture samples or renderings must be provided; municipal projects may impose higher durability requirements on components, in which case third-party test reports must be provided. Qinglong Group has a provincial-level engineering technology center and can achieve complex shapes and special effects through advanced processes such as 3D printing and CNC engraving. It has customized GRC walls with embossed textures for a number of cultural venue projects, earning high recognition from customers.

5. Quality Standards and Acceptance Specifications: The "Quality Benchmark" for Custom GRC Components

The technical documentation must clearly specify the quality standards and acceptance specifications for GRC components, including dimensional deviations (e.g., length deviation ≤5mm/m), surface flatness (≤3mm/2m), and crack control (no through cracks allowed). Qinglong Group has established a strict quality control system, executing standardized processes from raw material inspection to finished product delivery, and can provide factory inspection reports according to project requirements. For large projects, we can also cooperate with the owner in third-party spot checks to ensure that product quality meets design requirements.

As one of the larger GRC manufacturers in China, Qinglong Group has always upheld the principle of "meticulousness and the pursuit of excellence", providing customers with one-stop solutions from detailed design to after-sales maintenance through its full-chain service capabilities. Whether it is special-shaped GRC ceilings for theaters or European-style decorative lines for commercial complexes, providing complete and accurate technical documentation is the foundation for perfect customization.
