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

When architectural aesthetics meet structural limits, UHPC interprets the mechanical code of "openwork art" with millimeter-level precision. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group is redefining the boundaries of what highly perforated architectural forms can achieve through the deep integration of materials science and engineering technology.

In contemporary architectural design, highly perforated forms have become a signature element showcasing artistic tension and technical strength. From the lightweight curtain walls of grand theaters to the parametric skins of commercial complexes, designers are placing unprecedented demands on the complexity and transparency of openwork structures. However, traditional materials often face bottlenecks such as excessive self-weight and insufficient structural stability when achieving large-span, highly perforated forms. This is where UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent toughness, and outstanding plasticity, becomes the core solution to this technical challenge. As a national high-tech enterprise backed by 28 years of full-chain experience, Qinglong Group has accumulated unique technical advantages in the detailed design, production, and construction installation of highly perforated UHPC forms.

Material Mechanics Breakthroughs of Highly Perforated UHPC Forms: Systematic Innovation from Formulation to Process

The key to achieving high perforation rates lies in precise control of material performance. Qinglong Group's R&D team optimized steel fiber content and gradation design, enabling UHPC components to achieve flexural strength exceeding 20MPa and compressive strength above 150MPa—a 3-5 fold improvement over traditional GRC materials. In the Nanjing East Road Century Plaza renovation project, Qinglong applied its self-developed translucent UHPC formulation, using a composite system of 200-mesh ultra-fine silica fume and nano calcium carbonate to achieve a 30% perforation rate while meeting the special requirement of 12% light transmittance; the project won the Silver Award of the first UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup). In production, Qinglong's proprietary "vacuum high-pressure infusion + steam curing" process keeps the minimum wall thickness of perforated components at 15mm with porosity deviation of no more than 2%, providing millimeter-level precision for complex forms.

Structural Optimization and Digital Design: The Engineering Path to Highly Perforated Forms

Safely realizing highly perforated forms depends on innovation in structural systems. Qinglong's technical team applied BIM technology and parametric design software (Rhino+Grasshopper) to build topology optimization models of perforated units, simulated stress distribution under different loads through finite element analysis, and transformed traditional solid structures into "skeleton-style" load-bearing frames. For the Dongguan Women and Children's Activity Center project, Qinglong developed a "honeycomb rib beam support system" for its signature perforated relief curtain wall, reducing the weight of UHPC panels up to 8㎡ in area by 40% and raising the perforation rate to 45%, while enabling full life-cycle quality traceability through embedded RFID chips. This closed digital loop of "design-simulation-manufacturing" is a testament to Qinglong's technical strength as a participant in industry standard-setting (General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC), Plan No. 2024-0232T-JC).

Full-Chain Services Empowering Highly Perforated Projects: The Qinglong Solution from Concept to Delivery

As a comprehensive service provider integrating detailed design, production, construction installation, and after-sales maintenance, Qinglong Group has built a full-process assurance system for highly perforated form projects. In the detailed design stage, it provides one-stop technical support covering scheme optimization, joint detailing, and mold design; production relies on the 600,000-square-meter annual capacity of its Nanning, Guangxi production base, with automated lines ensuring component consistency; in construction installation, 3D laser scanning positioning technology achieves "zero-error" assembly of perforated units. From domestic landmark buildings to overseas projects in Southeast Asia, Qinglong has completed more than 200 highly complex UHPC/GRC/GRG/GRP engineering cases, including a hyperbolic perforated GRP roof for a cultural tourism project in Malaysia that set an industry record with 1.2mm installation precision.

From material innovation to engineering practice, breakthroughs in highly perforated UHPC form technology represent not only a victory of materials science but also the collaborative innovation of design thinking and engineering technology. Guided by its mission of "creating beautiful architecture," Qinglong Group will continue to push the application boundaries of UHPC/GRC/GRG/GRP materials in architectural decoration, providing designers and owners with expert-level solutions that combine aesthetic value and technical feasibility, and helping Chinese architecture achieve the leap from "manufacturing" to "intelligent manufacturing."
