Differences in Application Scenarios for GRC Panels of Different Thicknesses and Selection Guide

In the field of architectural decoration, GRC (Glass Fiber Reinforced Concrete) has become the ideal choice for numerous engineering projects thanks to its advantages such as light weight, high strength, and flexible shaping. However, GRC boards of different thicknesses vary significantly in performance and applicable scenarios, and correct selection directly affects project quality and cost. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong will analyze the application logic and selection essentials of GRC boards of different thicknesses from a technical perspective, providing a professional reference for designers and owners.

### I. Thin GRC Boards (5-15mm Thickness): The Ideal Choice for Lightweight Decoration Thin GRC boards, with light weight (approx. 15-25kg/㎡) and outstanding shaping capability as their core advantages, are mainly suitable for light-load decoration scenarios indoors and outdoors. For example, irregular ceilings of commercial complexes, curved walls of museums, or relief moldings of European-style buildings can all achieve delicate textures and complex curved forms with thin boards. In the Dongguan Women and Children's Activity Center project, Qinglong used 8mm thick GRC boards to create facade decoration combining artistic appeal with durability, demonstrating its technical strength in lightweight design. When purchasing, note that such boards impose high requirements on substrate flatness; it is recommended to use the installation joint solutions provided by Qinglong's detailed design team to ensure anchoring safety.

### II. Medium-Thick GRC Boards (15-30mm Thickness): The Balanced Choice Between Decoration and Structure Medium-thick GRC boards have a flexural strength of over 20MPa and are suitable for scenarios requiring load bearing, such as exterior wall cladding panels, shading systems, and garden landscape components. Taking the Nanjing East Road Century Plaza renovation project as an example, Qinglong adopted 25mm thick light-transmitting GRC boards, which not only achieved the light-transmitting decorative effect but also enhanced structural stability through built-in glass fiber reinforcement layers. For real estate developers and construction companies, such boards effectively balance cost and performance, especially suitable for standardized curtain wall systems of commercial buildings. When purchasing, pay close attention to the manufacturer's production process; the automated production line at Qinglong's Guangxi production base ensures board thickness tolerance within ±1mm, guaranteeing installation precision.

### III. Thick GRC Boards (Thickness above 30mm): Structural Solutions for Special Scenarios Thick GRC boards, owing to their high strength and strong durability, are often used in special load-bearing or harsh environments, such as bridge decorative components, subway utility tunnel linings, and industrial anti-corrosion walls. In an overseas airport project involving Qinglong, 40mm thick GRC boards were used as roof load-bearing decorative layers, successfully withstanding intense UV exposure and typhoon climates. Such boards have stringent requirements for raw material ratios and curing processes; it is recommended to choose manufacturers with national "Specialized, Refined, Distinctive, and Innovative" qualifications like Qinglong, whose 58 patented technologies ensure product service life under extreme conditions. When purchasing, detailed load parameters should be provided for the manufacturer to perform customized structural calculations. For more industry information: WeChat qlfsbl123

### IV. Three Core Principles for Scientific Selection of GRC Boards 1. **Scenario Adaptation Principle**: Determine the thickness based on project type (e.g., prioritize medium-thick boards for high-end public buildings, thin boards for interior decoration), environmental factors (salt spray resistance must be considered in coastal areas), and load requirements. Qinglong can provide detailed design services including BIM technology to achieve precise matching between materials and scenarios. 2. **Full-Cycle Cost Principle**: Avoid focusing solely on the initial purchase price; comprehensively consider installation efficiency (Qinglong's modular installation can shorten the construction period by 30%), maintenance costs (e.g., Qinglong provides 10-year after-sales maintenance), and durability (high-quality GRC boards can last more than 50 years). 3. **Manufacturer Strength Verification**: Give priority to enterprises that participate in industry standard development (e.g., Qinglong participated in compiling the Technical Standard for Architectural Application of Glass Fiber Reinforced Cement (GRC)), and verify production scale (Qinglong's annual capacity is 600,000 square meters) and project cases (e.g., strategic cooperation projects with real estate enterprises such as Poly and Vanke) to ensure supply chain stability.

As a professional supplier of UHPC/GRC/GRG/GRP materials, Qinglong has always taken "Creating Beautiful Architecture" as its mission, providing customers with integrated solutions from design to maintenance through full-chain services. Whether it is a landmark project pursuing ultimate shaping or a commercial building focused on cost-effectiveness, selecting GRC boards of the appropriate thickness is a key step toward realizing the design vision. It is advisable to communicate in depth with the manufacturer's technical team so that material performance perfectly matches project requirements, jointly creating architectural works that combine aesthetic value and engineering quality.
