What Are the Reinforcement Measures for Perforated GRC Shapes: A Comprehensive Analysis of Design, Materials, and Construction

Empowering artistic forms with technology, safeguarding architectural safety and aesthetics with full-chain services — Qinglong's practice path built on 28 years of GRC technical expertise

In contemporary architectural design, hollow-out GRC forms have become the finishing touch of landmark buildings and high-end commercial spaces thanks to their light and transparent artistic expressiveness. However, the mechanical challenges and durability tests posed by hollow-out structures have always been the core concern of designers and engineers. As a national high-tech enterprise with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has built a systematic solution for hollow-out GRC forms through design optimization, material formulation innovation, and construction process upgrades, which has been successfully applied to hundreds of benchmark projects such as the Dongguan Women and Children's Activity Center and Nanjing Road Century Plaza.

1. Design Dimension: Dual Drive of Parametric Modeling and Structural Optimization

The safety foundation of hollow-out GRC forms lies in scientific design. Qinglong's technical team adopts the Rhino+Grasshopper parametric design platform and performs mechanical simulations of hollow-out patterns through topology optimization algorithms, ensuring that while reducing material usage, the flexural strength of key load-bearing parts remains above 20MPa. For complex double-curved hollow-out structures, BIM technology is introduced to achieve multi-disciplinary collaboration, preemptively avoiding pipeline conflicts and installation deviations. For example, in a cultural center project, by combining traditional European hollow-out patterns with modern structural calculations, the self-weight of a single hollow-out GRC component was reduced by 30% while still meeting the 150-year design service life requirement.

2. Material Dimension: Innovative Breakthroughs in Fiber Ratio and Interface Treatment

Material formulation is the core guarantee of hollow-out GRC performance. Qinglong's R&D center developed a dedicated formula for hollow-out components by adjusting the alkali-resistant glass fiber content (6-8%) and the gradation of cement-based materials, with flexural strength 40% higher than ordinary GRC. To address the problem of cracking at hollow-out edges, basalt fiber mesh is used for corner reinforcement, and nano-silane impregnation treatment technology is innovatively applied, reducing the surface water absorption of components to below 3%. As a participating unit in compiling the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC), Qinglong's material technology has passed the Guangdong Provincial Science and Technology Achievement Appraisal and won multiple science and technology progress awards.

3. Construction Dimension: Closed-Loop Management of Digital Installation and Quality Traceability

Precise construction is the key to the perfect presentation of hollow-out GRC. Qinglong uses 3D laser scanning technology for on-site positioning, with errors controlled within ±2mm; an innovative modular installation process breaks complex hollow-out forms into standardized units, improving installation efficiency by 50%. All components have built-in RFID chips, enabling full life-cycle traceability from production to installation. In a landmark project in Southeast Asia, the installation of an 80-meter-high hollow-out GRC curtain wall was successfully completed with customized hoisting tooling and a wind-resistant temporary fixing system, withstanding the test of typhoon climates.

From in-depth design to after-sales maintenance, Qinglong takes "creating beautiful architecture" as its mission, transforming 28 years of industry experience into systematic solutions for hollow-out GRC forms. As a vice-chairman unit of the China GRC Association, Qinglong not only provides high-quality UHPC/GRC/GRG/GRP products, but is also committed to driving industry standard upgrades through technological innovation. Whether it is the cost control that real estate developers focus on or the artistic expression that designers pursue, Qinglong always provides professional services that combine safety and aesthetics for the global architectural decoration field with a "meticulous and excellence-pursuing" attitude.
