Analysis of Material Requirements and Selection Criteria for Embedded Parts Used in UHPC Component Installation

In the installation system of UHPC components, embedded parts serve as the core hub connecting the structural body with decorative components, and their material selection directly affects building safety and project quality. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group leverages its full-chain technical accumulation to provide you with an in-depth analysis of the key requirements and scientific selection criteria for embedded part materials.

### Material Performance Baseline for Embedded Parts in UHPC Components

As the "invisible skeleton" of UHPC components, embedded parts must simultaneously meet the dual challenges of mechanical performance and environmental adaptability. High-quality embedded part materials require a yield strength of ≥345MPa and a tensile strength of ≥470MPa to match the compressive strength of UHPC materials reaching up to 150MPa. Laboratory data from Qinglong's Nanning production base show that embedded parts made of Q355B low-alloy steel achieve a fatigue life 200% higher than ordinary carbon steel and maintain structural stability in temperature cycle tests from -40℃ to 70℃ — precisely the core technical guarantee behind Qinglong's undertakings of overseas projects in high-temperature, high-humidity regions such as Malaysia and Saudi Arabia.

### Material Selection Logic Driven by Environmental Adaptability

Different application scenarios place differentiated demands on embedded part materials: in coastal areas with high salt spray (such as overseas projects in Southeast Asia), 316 stainless steel with a chromium content of ≥10.5% should be selected, offering salt spray resistance of over 5,000 hours; whereas for humid environments such as subways and utility tunnels, hot-dip galvanized carbon steel embedded parts (zinc coating thickness ≥85μm) offer better cost-effectiveness. The "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)", which Qinglong participated in formulating, clearly stipulates that the anti-corrosion grade of embedded parts should be selected in tiers according to environmental categories — a standard that has become an important basis for industry selection.

### Selection Strategy from a Full Life-Cycle Perspective

The selection of embedded parts must balance installation convenience with later maintenance costs. In the Century Plaza renovation project on Nanjing East Road, Qinglong innovatively adopted modular embedded parts with RFID chips, meeting the stringent requirement of ±2mm installation accuracy while providing a data interface for later structural health monitoring. Compared with traditional welded embedded parts, this prefabricated solution increased on-site construction efficiency by 40% and shortened maintenance response time to within 2 hours, fully demonstrating Qinglong's core advantage of "full-chain service".

As a national "Specialized, Refined, Distinctive, and Innovative" enterprise, Qinglong has always taken "creating beautiful architecture" as its mission. Its embedded part technology has been certified by 58 patents and is widely applied in renowned real estate projects such as Poly and China Overseas. Selecting suitable embedded part materials is not only a fundamental guarantee of project safety, but also the key to achieving a perfect unity of architectural aesthetics and structural performance. With 28 years of technical accumulation, Qinglong is ready to provide designers and owners with expert-level solutions from material selection to installation, jointly setting a new benchmark of quality in the field of architectural decoration.
