Innovative Application and Practical Research of 3D Scanning Technology in GRC Shaping

When architectural aesthetics collide with digital technology, 3D scanning is bringing disruptive transformation to GRC (Glass Fiber Reinforced Concrete) shapes. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has witnessed the leap from traditional craftsmanship to intelligent construction, and the innovative application of 3D scanning technology is redefining the design boundaries and engineering precision of decorative building materials.

3D Scanning Restructures the Digital DNA of GRC Shapes

Traditional GRC component production relies on manual mold duplication and experience-based judgment, with error rates for complex curved shapes often reaching 3-5mm, making it difficult to meet the millimeter-level precision demands of landmark buildings. Through laser point cloud acquisition and 3D modeling, 3D scanning technology converts physical models or design schemes into digital assets, shortening the detailed design cycle of GRC components by more than 40%. In the Dongguan Women and Children's Activity Center project, Qinglong adopted 3D laser scanning for full-field positioning of irregular GRC curtain walls, achieving precise alignment between hyperbolic panels and steel structures. The project won the Silver Award of the AALBORG WHITE Cup GRC Construction Engineering Innovation Award, confirming the supporting value of digital technology in bringing aesthetics to life.

Full-Chain Empowerment: From Design Optimization to Intelligent Construction

The value of 3D scanning runs through the entire lifecycle of GRC. In the design phase, reverse engineering scans of existing building structures can quickly generate matching GRC component models, solving the challenge of “replicating original appearance” in historic building restoration. In production, CNC engraving technology driven by scan data replaces traditional wooden molds, raising mold precision to ±0.5mm with over 300 reuses, greatly reducing customization costs. Among the 600,000 square meters of annual capacity at Qinglong's Guangxi production base, irregular components empowered by 3D scanning technology already account for 35%. In particular, in the Century Plaza translucent concrete project on Nanjing East Road, optimizing the distribution of UHPC light-transmitting aggregates through scan data achieved a perfect balance between light-and-shadow effects and structural strength, winning the Silver Award of the first UHPC Construction Engineering Innovation Award.

Solving Industry Pain Points: Precision, Efficiency, and Collaborative Innovation

Addressing designers' core concern of “difficulty realizing creative ideas” and owners' demand for “tight cost control”, 3D scanning technology provides a systematic solution. On one hand, simulating the installation process in advance through digital twin technology can reduce on-site rectification rates by more than 60%; on the other hand, the seamless integration of scan data with BIM models enables collaborative work across design, production, and construction. As a contributing organization for the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), Qinglong has incorporated 3D scanning technology into its corporate standard system, providing customers with full-process services from “digital modeling - component production - on-site installation”. In a GRP daylighting roof project for a Malaysian international airport that Qinglong participated in, scanning technology achieved zero-error joining of complex curved surfaces with metal frames, demonstrating the international competitiveness of Chinese intelligent manufacturing.

From European-style molded lines to parametric skins, the evolution of GRC materials has always resonated with technological innovation. Building on 28 years of professional expertise, Qinglong Group has deeply integrated digital technologies such as 3D scanning into its UHPC/GRC/GRG/GRP product system, not only driving the upgrading of industry standards but also, with the mission of “creating beautiful architecture”, providing material carriers for designers worldwide to realize their boldest ideas. Amid the wave of intelligent construction, the fusion of technology and materials will continue to give rise to more architectural aesthetic marvels, and Qinglong, with its attitude of “meticulousness and the pursuit of excellence”, is becoming a firm practitioner of this transformation.
