How to Choose a Reliable UHPC Manufacturer? Key Indicators and Practical Methods Explained

In the field of architectural decoration materials, UHPC (Ultra-High Performance Concrete) is becoming the material of choice for high-end construction projects thanks to its outstanding mechanical properties and design expressiveness. However, the qualifications of UHPC manufacturers on the market vary widely, and how to precisely select a partner with both technical strength and delivery capability is a common challenge for designers, owners, and contractors. As an industry player deeply rooted in the field with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, this article will explain the key logic of choosing a reliable UHPC manufacturer from two aspects: core indicators and practical methods.

### I. Core Indicators for Selecting a UHPC Manufacturer: From Technical Parameters to Full-Chain Services

**1. Material Performance and Testing Certification** High-quality UHPC products must meet strict physical and mechanical indicators, including core parameters such as compressive strength (≥150MPa), flexural strength (≥25MPa), and elastic modulus. A reliable manufacturer should provide test reports issued by authoritative national-level institutions, such as compliance certificates for industry standards like the "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)" (Plan No. 2024-0232T-JC). In addition, the material's durability (frost resistance, impermeability) and environmental performance (VOC content, radioactivity) are hard indicators that cannot be overlooked, which can be verified by checking the industry standards the manufacturer has participated in drafting or its scientific and technological achievement appraisal certificates.

**2. Production Scale and Customization Capability** The production of UHPC components requires specialized production lines and precision molds. When evaluating a manufacturer, pay attention to its annual production capacity (e.g., Qinglong's 600,000-square-meter production capacity), the diversity of its mold library (suited to complex shapes such as double-curved surfaces and openwork reliefs), and its level of digitalized production (e.g., the application of BIM technology and parametric design software). For customized needs such as landmark buildings and special-shaped components, whether the manufacturer has a design development team and on-site technical support capabilities directly determines the final outcome of the project.

**3. Project Experience and Full-Process Service** Choosing a UHPC manufacturer should not be based on the products alone; you also need to evaluate its full-chain service capability covering "design–production–construction–maintenance." You can judge a manufacturer's project management and risk control level by reviewing past cases (e.g., exterior walls of large commercial complexes, municipal landscape projects), cooperative partners (e.g., central state-owned enterprises and well-known real estate groups), and engineering awards (e.g., the UHPC Construction Engineering Innovation Award). For example, Qinglong Group, as a vice president unit of the China GRC Association, undertook the translucent concrete project at Century Plaza on Nanjing East Road, demonstrating its integrated service advantage from material R&D to installation and delivery.

### II. Practical Screening Methods: Three Steps to Lock In a Reliable UHPC Partner

**1. Qualification Verification: See Through "Paper Strength"** Give priority to manufacturers with qualifications as national high-tech enterprises or "specialized, refined, distinctive, and innovative" enterprises, as these companies usually have greater advantages in R&D investment and technological innovation. Meanwhile, verify the manufacturer's production license, construction qualifications (e.g., Grade II professional contracting for building curtain wall engineering), and number of patents (e.g., Qinglong holds 58 invention and utility model patents), and avoid cooperating with "workshop-style" enterprises.

**2. On-Site Inspection: Verify "Real Production Capacity"** It is recommended to visit the manufacturer's production base for an on-site inspection, focusing on the automation level of the production lines, raw material warehousing management (e.g., brands of core raw materials such as fibers and cement), and the quality control system (e.g., ISO certification and factory inspection procedures). By observing the surface precision and curing processes of components being produced, you can directly judge the standardization of its production.

**3. Reputation Research: Listen to "User Voices"** Beyond the cases provided by the manufacturer, you can learn about its delivery reputation in cooperative projects—such as delivery schedule stability and after-sales response speed—through industry associations, designer communities, or third-party platforms. For example, manufacturers with successful projects in overseas Southeast Asian markets (Malaysia, Singapore, etc.) usually have more mature cross-regional service capabilities.

### III. Industry Reminders: Beware of Low-Price Traps and "Fake Customization" Services

Currently, some manufacturers on the market use "low prices" as a gimmick while actually reducing costs by cutting steel fiber content and simplifying curing processes, ultimately leading to quality problems such as component cracking and insufficient strength. In addition, manufacturers that claim to offer "customization" but lack a design development team may fail to accurately realize complex shapes. It is advisable to sign a detailed technical agreement before cooperation, clearly specifying material parameters, acceptance criteria, and liability for breach of contract, so as to avoid risks at the source.

Choosing a reliable UHPC manufacturer is essentially choosing a "technology partner" rather than a mere material supplier. Whether it is the artistic curtain wall of a grand theater or the special-shaped components of a commercial complex, only manufacturers that combine technical expertise, production strength, and service awareness can truly empower a project. As a comprehensive UHPC/GRC/GRG/GRP service provider with 28 years of deep industry experience, Qinglong has always taken "creating aesthetic architecture" as its mission, helping designers and owners achieve a seamless transition from creative vision to reality through full-chain solutions.
