Parametric Design Process and Key Technologies for Custom GRC Shapes

In the field of contemporary architectural design, irregular shapes are becoming an important vehicle for showcasing the fusion of architectural aesthetics and technology, while GRC (Glass Fiber Reinforced Concrete), with its exceptional plasticity and structural performance, has become the ideal material for realizing complex architectural forms. Qinglong Group, an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, seamlessly connects artistic creativity with engineering practice through parametric design technology, creating architectural skins that combine visual impact with structural safety for over a thousand landmark projects.

Parametric Design of GRC Irregular Shapes: A Full-Process Analysis from Concept to Completion

Parametric design is the core engine for realizing GRC irregular shapes, and its process covers three key stages: first, design parametrization, which uses tools such as Rhino+Grasshopper to build mathematical models that translate architects' creative concepts into quantifiable parametric logic, such as hyperbolic curvature and openwork texture density; second, engineering parametrization, which combines material mechanical properties (e.g., GRC flexural strength ≥20MPa) with production process constraints to optimize mold design and panel segmentation schemes; and finally, construction parametrization, which uses BIM technology and 3D laser scanning to achieve millimeter-level precision control in on-site installation. In the renovation project of Century Plaza on Nanjing East Road, Qinglong Group successfully combined translucent concrete with GRC irregular components through this process, winning the Silver Award of the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

Key Technical Breakthroughs: Collaborative Innovation in Materials, Processes, and Digitalization

The technical challenges in realizing GRC irregular shapes center on three dimensions: material formulation optimization, mold technology innovation, and digital management. At the material level, Qinglong's specially developed GRC spray mortar formulation adjusts glass fiber content and cement-based material ratios, enabling components to be as thin as 15mm while still meeting C50 strength requirements; in terms of molds, the combination of reusable flexible silicone molds and modular steel molds solves the forming challenges of hyperbolic components, improving production efficiency by 40% compared with traditional processes; in digital management, an RFID chip traceability system has been introduced to achieve full lifecycle data tracking from design to installation, ensuring the precise realization of complex shapes in projects such as the Dongguan Women and Children's Activity Center.

Qinglong's Full-Chain Service: Expert-Level Support from Design Development to After-Sales Maintenance

As a National High-Tech Enterprise and a participant in GRC industry standard setting, Qinglong Group has built a full-chain service system covering design development, manufacturing, construction installation, and after-sales maintenance. Tailored solutions are provided for the core needs of real estate developers and architectural design institutes: for example, optimizing the panel segmentation scheme of irregular GRC curtain walls for commercial complex projects, reducing transportation and installation costs while ensuring shape integrity; providing acoustically optimized GRG ceiling systems for cultural venue projects, achieving optimal sound field effects through parametric adjustment of curved surfaces. To date, Qinglong has established a production capacity of 600,000 square meters of GRC/GRG products, with services covering more than 30 provinces and cities in China as well as overseas markets in Southeast Asia.

From the dynamic curves of landmark buildings to the artistic skins of commercial spaces, the parametric design of GRC irregular shapes is redefining the possibilities of architecture. Built on 28 years of technological accumulation, Qinglong Group will continue to promote the deep integration of new materials, new processes, and digital technology, empowering designers and owners throughout the entire journey from concept to realization, and advancing the mission of "creating aesthetically beautiful architecture." On the path of exploring future architectural aesthetics, GRC parametric technology will become the key bridge connecting artistic imagination and engineering practice.
