Must UHPC Manufacturers Comply with the GB/T 31387-2025 National Standard?

In the field of architectural decoration materials, standard compliance is an important yardstick for measuring product quality and corporate strength. Recently, discussions on "whether UHPC manufacturers must comply with the GB/T 31387—2025 national standard" have attracted widespread attention. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group will provide professional analysis for designers, owners, and industry peers from three dimensions: standard interpretation, industry status, and corporate practice.

### I. Core Positioning and Mandatory Nature of the GB/T 31387—2025 National Standard

As the latest national standard in the field of ultra-high performance concrete (UHPC), GB/T 31387—2025 clearly specifies the technical requirements, test methods, inspection rules, and application specifications for UHPC materials. It should be emphasized that this standard is a recommended national standard (GB/T) rather than a mandatory standard (GB). This means that, from a legal standpoint, UHPC manufacturers are not "required" to enforce it, but this does not weaken its guiding significance and authority in the industry. For UHPC manufacturers pursuing high quality, proactively meeting or even exceeding this standard has become an "invisible threshold" for entering the high-end market.

### II. Why Are Leading UHPC Manufacturers Choosing Compliance?

1. **An Inevitable Choice Amid Market Competition** Against the backdrop of rapid expansion of the UHPC market, standards have become an important basis for screening quality suppliers. Taking Qinglong Group as an example, as a national high-tech enterprise and a "specialized, refined, distinctive, and innovative" enterprise, it has not only participated in the formulation of industry standards such as the "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)," but has also integrated the core indicators of GB/T 31387—2025 into the entire production process. Through intelligent production lines with an annual capacity of 600,000 square meters, Qinglong UHPC products meet or exceed national standards in terms of compressive strength, durability, process precision, and more, making them the preferred supplier for real estate, municipal, and overseas projects.

2. **Dual Assurance of Engineering Safety and Reputation** Although the standard is not mandatory, owners and designers of large projects such as commercial complexes and landmark buildings usually require UHPC manufacturers to provide test reports compliant with national standards. In the light-transmitting concrete project of the Nanjing East Road Century Plaza renovation undertaken by Qinglong Group, the products' high-standard performance won the "AALBORG WHITE Cup First UHPC Construction Engineering Innovation Award Silver Award," confirming the positive value of compliance for project quality and corporate reputation.

### III. Qinglong UHPC's Compliance Practice: Full-Chain Control from Standard to Implementation

As a custom manufacturer of UHPC/GRC/GRG/GRP materials, Qinglong Group, with the mission of "creating beautiful architecture," runs standard compliance through the entire chain of detailed design, production and manufacturing, and construction and installation: - **Technical R&D**: Relying on a provincial-level R&D center, a material database has been established to ensure UHPC formulations meet key indicators in GB/T 31387—2025 such as fiber content and chloride ion content; - **Production Control**: Introducing BIM technology and automated production lines to achieve component precision error ≤2mm, far exceeding standard requirements; - **Project Services**: Providing customers with "one-stop" solutions from material selection to after-sales maintenance; for example, in an overseas airport project, Qinglong UHPC exterior wall panels passed testing by a local authoritative institution, with weather resistance indicators meeting the dual requirements of GB/T 31387—2025 and international standards.

### IV. Advice for Owners and Designers: How to Choose a Compliant UHPC Manufacturer?

1. **Verify Qualifications and Standards Participation**: Give priority to manufacturers that, like Qinglong Group, participate in national standard formulation and own patented technologies, as they have a deeper understanding of the standards; 2. **Request Full-Process Test Reports**: Including raw material inspection, finished product performance testing (such as flexural strength and elastic modulus), and construction process evaluation; 3. **Review Project Cases**: Verify the manufacturer's compliance capability and implementation experience through the actual application results of landmark projects (such as grand theaters and museums).

The implementation of the GB/T 31387—2025 national standard marks the transformation of the UHPC industry from "unruly growth" to "standardized development." For UHPC manufacturers, proactively embracing the standard is an inevitable choice to enhance core competitiveness; for owners and designers, choosing a compliant manufacturer is the key to ensuring project quality. Qinglong Group will continue to promote the high-quality application of UHPC materials in the field of architectural decoration with a "meticulous and excellence-pursuing" attitude, helping realize the vision of "becoming a world-class leading UHPC manufacturing enterprise."
