Discussion on Material Requirements and Selection Criteria for Embedded Parts Used in UHPC Component Installation

In the installation system of UHPC components, embedded parts serve as invisible “bones,” and their material selection directly affects the safety and durability of architectural decoration. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group draws on full-chain technical experience to thoroughly analyze the core requirements and scientific selection standards for embedded part materials, providing professional solutions for designers and owners.

Material Performance Benchmarks for UHPC Embedded Parts: From Mechanical Strength to Environmental Adaptability

UHPC components are typically used in high-end buildings such as grand theaters and commercial complexes, and their embedded parts must simultaneously meet three core indicators: load-bearing capacity, pull-out resistance, and weather resistance. Verified through more than a thousand engineering practices, the Qinglong technical team has established that high-quality embedded part materials should have a yield strength of ≥345MPa and an elongation of no less than 20% to cope with the stress transmission resulting from the inherent high strength of UHPC materials. In terms of material types, Q355B low-alloy high-strength structural steel, with its excellent comprehensive mechanical properties, has become the first choice for most load-bearing scenarios; in coastal high-salt-spray environments, hot-dip galvanized Q235B steel achieves long-term corrosion protection with a zinc layer thickness of over 80μm—a standard already incorporated into Qinglong’s “Technical Specification for Embedded Parts of UHPC Components.”

Three Dimensions of Selection Standards: Engineering Scenarios, Cost Optimization, and Full Life-Cycle Considerations

Qinglong has established a “scenario adaptation” model for embedded part selection: for dynamic load scenarios such as external curtain wall installations, ribbed plate-type embedded parts are used to distribute loads to the base structure through an increased anchorage area; static load-bearing scenarios such as garden landscapes can adopt economical anchor bolt combination solutions. Notably, embedded part material selection must also take cost balance into account—for example, using Q235B base material with cold zinc spray treatment in non-critical areas can reduce material costs by 30% compared with a full stainless steel solution, while still meeting design service life requirements. Qinglong’s detailed design team performs load simulations based on BIM models to ensure that material performance precisely matches engineering requirements.

Solving Industry Pain Points: Full-Chain Control from Material Certification to Installation Processes

The current market faces problems such as substandard embedded part materials and inadequate anti-corrosion treatment, leading to later-stage risks such as rust expansion and component detachment. As a national high-tech enterprise, Qinglong has established a strict incoming material inspection mechanism, requiring material certificates and third-party mechanical testing reports for every batch of embedded parts. During construction, 3D laser positioning technology ensures an embedded part installation error of ≤2mm, and RFID chips are innovatively embedded in key components to achieve full life-cycle quality traceability. This three-dimensional control system of “materials + processes + management” has been successfully applied to benchmark projects such as the Nanjing East Road Century Plaza renovation.

As a participating drafting unit of the industry standard “General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC),” Qinglong has always upheld the mission of “creating beautiful architecture,” regarding embedded part material selection as a core element of UHPC system safety. Going forward, Qinglong will continue to explore new embedded part technologies such as carbon fiber composite materials, providing the architectural decoration industry with safer and more durable system solutions and fulfilling its vision of “becoming an outstanding world-leading UHPC/GRC/GRG/GRP manufacturing enterprise.”
