Exploring the Limits of UHPC Stone-Imitation Large Panels: Maximum Single-Panel Area and Realization Paths

UHPC imitation stone panels, with their advantages of lightweight high strength and high realism, have become a new favorite in modern building facade decoration, and breakthroughs in maximum single-panel area are a core indicator of a company's technical strength. Leveraging 28 years of technical accumulation and engineering practice, Qinglong Group has continuously made breakthroughs in the field of ultra-large-format UHPC imitation stone panels, providing more impactful decorative solutions for landmark buildings.

I. Reference for Current Industry Mainstream Maximum Single-Panel Area????

Based on material properties and production/construction conditions, the mainstream maximum single-panel area of current UHPC imitation stone panels can reach 12-15 square meters, with conventional thicknesses of 20-50mm. In the renovation project of Shanghai New World Century Plaza on Nanjing East Road, Qinglong successfully created a UHPC imitation wood translucent panel with a single-piece area of 12 square meters (3245*3530mm) and a weight of over 700kg, setting a new industry record for ultra-large-format components at that time. This breakthrough not only demonstrates the superior performance of UHPC materials, but also showcases the company's comprehensive strength in mold design, production technology, and hoisting techniques. For conventional projects, it is recommended to keep single-panel area within 8 square meters, balancing production efficiency and installation safety.

II. Core Factors Affecting Maximum Single-Panel Area

The maximum area of UHPC imitation stone panels is not unlimited and is constrained by multiple factors. First is material performance: UHPC must have sufficient flexural strength and toughness. Qinglong uses its self-developed mix ratio to achieve UHPC flexural strength above 20MPa, providing the foundation for ultra-large panel forming. Second is mold load-bearing capacity: ultra-large panel production requires customized high-strength molds. Qinglong uses a combined process of steel molds and polyurethane molds to ensure molds do not deform during pouring and curing. Third is transportation and installation conditions: panels over 12 square meters require dedicated transport vehicles and hoisting equipment. Qinglong employs modular transportation and precise on-site hoisting technology in its projects to ensure components are safely delivered and properly installed. In addition, structural load design is also crucial, requiring BIM technology to simulate load conditions and rationally arrange stiffening ribs and embedded parts.

III. Engineering Applications and Assurance Measures for Ultra-Large-Format Panels

Ultra-large UHPC imitation stone panels are mainly applied in high-end projects such as urban renewal, commercial complexes, and landmark buildings, reducing splicing joints and enhancing the overall aesthetics of buildings. In the Dongting Lake Museum project, Qinglong used 8,800 square meters of UHPC imitation stone panels, with a maximum single-panel area of 10 square meters, installed via a dry-hanging system with precision controlled within ±2mm, successfully recreating the sense of solidity of traditional stone architecture. To ensure the quality of ultra-large panels, Qinglong has established a full-process quality control system: the production stage uses vibrating table compaction and vacuum dewatering processes to ensure dense slurry; the curing stage uses steam curing to precisely control temperature and humidity; before leaving the factory, flexural strength, freeze resistance, and other performance tests are conducted, and all components are certified by authoritative third-party institutions.

As technology continues to advance, there is still room for improvement in the maximum area of UHPC imitation stone panels. As a National High-Tech Enterprise, Qinglong Group holds 58 patented technologies and continues to develop production processes for ultra-large-format components, while also participating in the formulation of the industry standard "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)", promoting the standardized development of the industry. From the Shenzhen Pingshan High-Tech Zone Comprehensive Service Center to the Hainan Poly Peninsula No.1 project, Qinglong empowers buildings with ultra-large UHPC panels.
