Key Technologies and Application Analysis for Achieving High Openwork Rates in UHPC Shapes

Carving light and shadow with technology and reconstructing the boundaries of architectural aesthetics with UHPC, Qinglong's 28 years of technical accumulation have forged a new benchmark for high openwork ratio designs.

In modern architectural design, high openwork ratio forms are becoming an important expression of artistic tension and structural aesthetics. As an industry leader in the field of UHPC/GRC/GRG/GRP materials, Qinglong Group, drawing on 28 years of full-chain experience, has deeply explored the technical breakthroughs and practical pathways of ultra-high performance concrete (UHPC) in achieving high openwork ratio designs, providing designers and owners with expert-level solutions from concept to implementation.

### The Technical Code of UHPC High Openwork Designs: Dual Empowerment of Material Properties and Structural Innovation

With its ultra-high strength (compressive strength exceeding 150MPa), excellent toughness, and outstanding durability, UHPC has become the ideal medium for realizing complex openwork designs. Through material formula optimization and fiber reinforcement technology, Qinglong has increased the flexural strength of UHPC to 3-5 times that of traditional concrete, ensuring that openwork structures maintain structural stability while reducing weight by 30%. Taking the Nanjing East Road Century Plaza renovation project as an example, its light-transmitting concrete components feature 0.2mm-level precision openwork textures; through a three-dimensional woven fiber framework and ultra-high-pressure casting processes, a perfect balance between light transmittance and structural safety was achieved. The project won the Silver Award of the first UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup).

### Full-Chain Solutions: Seamless Connection from Design Development to Construction Implementation

The realization of high openwork UHPC forms tests a company's full-chain integration capability. Relying on a national-level R&D center and a provincial-level engineering technology center, Qinglong has built a closed-loop system of "parametric design - BIM collaboration - intelligent manufacturing - precision installation." In the design development stage, the Rhino+Grasshopper parametric platform is adopted to transform designers' inspiration into quantifiable production data; in production, robotic carving and automated casting production lines are introduced to ensure that openwork detail tolerances are controlled within ±0.5mm; during construction and installation, 3D laser scanning positioning technology is applied to achieve "zero-error" assembly of complex curved components. This full-process control capability has enabled Qinglong to successfully undertake GRC/UHPC openwork decoration projects for landmark projects such as the Dongguan Women and Children's Activity Center.

### Scenario-Based Applications: Unlocking the Potential for Integrating Architectural Aesthetics and Functional Needs

UHPC high openwork designs demonstrate diverse value in the field of high-end architecture. In commercial complexes, their lightweight properties reduce building loads, while openwork textures can create artistic effects of interacting light and shadow; in cultural venues, adjusting the openwork ratio and texture density can optimize acoustic performance and daylighting; in landscape gardens, UHPC openwork components combine durability with ecological friendliness and can replace traditional stone to achieve sustainable design. With an annual production capacity of 600,000 square meters, Qinglong has supported more than a thousand domestic projects in making the leap from "drawing creativity" to "architectural reality," with products exported to overseas markets such as Southeast Asia and Australia.

As a national "Specialized, Refined, Distinctive, and Innovative" enterprise and a participant in industry standard-setting, Qinglong has always upheld the mission of "creating aesthetic architecture," deeply integrating material technology with artistic expression. Looking ahead, as UHPC becomes more widely adopted in architectural decoration, Qinglong will continue to explore the technical boundaries of higher openwork ratios and more complex forms, contributing the power of "Chinese intelligent manufacturing" to the world of architectural aesthetics.
