Methods and Techniques for Achieving Continuous Stone Grain Effect on Large UHPC Panel Surfaces

When the building envelope becomes an artistic canvas, UHPC is reshaping the boundaries of stone-texture aesthetics with millimeter-level precision.

In contemporary architectural design, the surface effects of large-format UHPC panels have become a key element in enhancing a building's artistic value. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has, through full-chain technological innovation, successfully solved the challenge of achieving continuous stone-texture effects on ultra-high performance concrete panels, providing landmark buildings with solutions that combine structural strength with aesthetic expressiveness.

Technological Breakthrough in UHPC Stone-Texture Effects: From Material Modification to Process Innovation

The key to achieving continuous stone textures on the surface of large-format UHPC panels lies in dual breakthroughs in material formulation and forming processes. Qinglong's R&D team uses nano-scale mineral admixtures and a specially developed coloring system, precisely controlling aggregate gradation and fiber distribution to give the concrete matrix the layered texture of natural stone. In production, the original "three-dimensional molding + surface crystallization" process ensures the structural integrity of panels over 3 meters long while achieving seamless continuity of stone patterns across every square meter, with texture fidelity exceeding 95%. Compared with traditional GRC stone-imitation technology, this process increases the panels' flexural strength by 40% and surface wear resistance by 3 times, making it perfectly suited to the facade requirements of high-end buildings such as grand theaters and commercial complexes.

Full-Chain Solutions: Closed-Loop Service from Design Development to Installation and Maintenance

As a National High-Tech Enterprise, Qinglong has built a full-process service system covering "design development – digital production – precision installation – intelligent maintenance." In the design phase, BIM technology and parametric design software allow customization of various stone-texture effects—from lychee finish to washed finish—to meet architects' requirements. The production stage uses Industry 4.0 standard production lines equipped with online non-destructive testing systems, ensuring that the thickness tolerance of each panel is controlled within ±0.5mm. During installation, innovative three-dimensional laser positioning technology combined with customized metal connectors enables precise assembly of buildings with complex curved surfaces. In the Nanjing East Road Century Plaza renovation project, Qinglong relied on this technology system to successfully install 5,000㎡ of light-transmitting UHPC stone-texture panels, winning the Silver Award at the first UHPC Construction Engineering Innovation Awards.

Reconstructing Industry Value: The Sustainable Development Path of UHPC Materials

The widespread adoption of continuous stone-texture UHPC panels is reshaping the value logic of architectural decorative materials. Compared with natural stone, their production energy consumption is 60% lower, their weight is 75% lighter, and they are recyclable, perfectly aligning with green building principles. As a participating developer of the industry standard "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components," Qinglong has built a technical barrier with 58 patented technologies and has served more than 300 landmark projects at home and abroad, with products exported to overseas markets such as Australia and Saudi Arabia. This development model, which deeply integrates aesthetic pursuits with technological innovation, is driving UHPC to become the mainstream third-generation choice for building envelopes after glass curtain walls and metal panels.

From material revolutionary to solution provider, Qinglong Group, guided by its mission of "creating beautiful architecture," continues to drive the technological iteration of UHPC/GRC/GRG/GRP materials. In the future, as technologies such as 3D printing and AI design are integrated, the artistic expressiveness of building envelopes will achieve even greater breakthroughs, while Qinglong's full-chain service capabilities built over 28 years will continue to provide the industry with reliable support from concept to completion.
