Key Techniques and Application Analysis for Achieving High Perforation Ratios in UHPC Shapes

In the field of contemporary architectural design, UHPC (Ultra-High Performance Concrete) has become the core material for achieving highly openwork architectural art, thanks to its outstanding mechanical properties and formative potential. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has broken through traditional process limitations in detailed design, manufacturing, and installation through full-chain technology integration, providing systematic solutions for the openwork aesthetics of landmark buildings.

Material Performance Breakthroughs of UHPC High-Openwork Forms High openwork ratio designs place stringent demands on material strength, toughness, and durability. With mechanical properties including compressive strength exceeding 150MPa and flexural strength above 20MPa, combined with a structural design featuring three-dimensionally randomly distributed steel fibers, UHPC achieves openwork ratios over 60% while still meeting building structural safety standards. Through its independently developed nano-scale silica fume admixture technology, Qinglong Group keeps the porosity of UHPC below 3%, significantly enhancing the material's impermeability and frost resistance and ensuring the long-term stability of openwork components in extreme environments. Compared with traditional GRC materials, UHPC can reduce self-weight by 30% under the same openwork structure, offering a better solution for large-span architectural forms.

Technological Synergy of Parametric Design and Digital Manufacturing The key to achieving high openwork ratios lies in the precise alignment of design and production. Qinglong Group adopts the Rhino+Grasshopper parametric design platform to build a parametric model library of openwork patterns, supporting gradient-based design of openwork aperture sizes from 0.5mm to 50mm. On the production side, through the deep integration of BIM technology and automated production lines, industrial-grade 3D scanning is used for mold precision calibration, keeping component forming errors within ±0.3mm. Taking the Nanjing East Road Century Plaza renovation project as an example, the Qinglong team achieved error-free assembly of 1,200 special-shaped components through parametric segmentation of light-transmitting UHPC openwork curtain walls, and the project won the Silver Award in the first UHPC Architectural Engineering Innovation Award (AALBORG WHITE Cup).

Process Innovation in Construction and Installation The installation precision of high-openwork UHPC components directly affects the building's final appearance. The "3D laser positioning + modular hoisting" process developed by Qinglong Group achieves full lifecycle traceability of components through embedded RFID chips; together with customized stainless steel connectors, installation errors are kept within 2mm/m. In the Dongguan Women and Children's Activity Center project, for curved openwork GRC-UHPC composite components, the "aerial assembly + stress release" technique was adopted, successfully resolving the installation stress concentration problem of large-curvature forms, and the project won the Silver Award of the GRC Architectural Engineering Innovation Award. In addition, the standardized installation process established by Qinglong has increased on-site construction efficiency for openwork components by 40%, effectively shortening project timelines.

Value Empowerment of the Full-Chain Service System As a national high-tech enterprise and a participant in formulating UHPC industry standards, Qinglong Group has built a full-chain service system covering everything from scheme consultation to after-sales maintenance. Addressing the core needs of real estate developers and architects, it provides customized solutions combining "design optimization + cost control"; for example, in commercial complex projects, replacing UHPC with GRG material on non-visible surfaces achieves 30% cost savings. Meanwhile, backed by production bases covering the whole country and overseas offices, Qinglong can deliver an openwork component capacity of 600,000 square meters per year, ensuring timely delivery of large projects. The industry standard General Technical Requirements for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC), which it helped compile, provides authoritative technical guidance for high-openwork UHPC applications.

From material performance improvement to digital construction innovation, UHPC high-openwork technology is reshaping the boundaries of architectural aesthetics. Building on 28 years of industry experience, Qinglong Group continues to provide designers and owners with a path to realizing "beautiful architecture" through technological innovation and full-chain services, driving UHPC to become a new-generation benchmark for architectural decoration materials after glass and stone.
