Is the Manufacturer's Quality Control Standard Higher Than the National Standard?

In the field of architectural decoration materials, product quality is the core guarantee of project safety and durability. National standards serve as the industry baseline, ensuring the basic performance and safety requirements of materials, while whether a brand enterprise's quality control standards exceed national standards has become a key indicator of its technical strength and sense of responsibility. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has always held itself to the self-imposed requirement of "exceeding national standards," building a full-chain quality control system to provide designers and owners with customized solutions that combine safety with artistry.

### I. The Essential Difference Between National Standards and Enterprise Standards: From the "Pass Line" to the "Excellence Line"

As mandatory requirements, national standards specify the minimum performance indicators of materials: for example, the flexural strength of GRC materials must be ≥10MPa (Technical Standard for Building Applications of Glass Fibre Reinforced Cement (GRC), JGJ/T423-2018), and the compressive strength of UHPC must be ≥120MPa (General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components, Plan No. 2024-0232T-JC). On this basis, Qinglong Group's enterprise standards set higher requirements: GRC flexural strength is controlled above 20MPa, UHPC compressive strength reaches 150MPa, and materials pass 1,000 freeze-thaw cycle tests (the national standard is 200 cycles), ensuring material stability in extreme environments. This positioning of "national standards as the base, enterprise standards as the peak" stems from reverence for engineering safety and an extreme pursuit of product quality.

### II. Full-Chain Quality Control: Closed-Loop Management from Laboratory to Construction Site

The core of quality control lies in whole-process penetration. Qinglong Group has established a five-dimensional control system of "detailed design—raw material testing—production monitoring—installation acceptance—after-sales maintenance": at the raw material end, imported glass fiber and special cement are used, and every batch of materials must pass 32 indicator tests; in production, German fully automated production lines are introduced, achieving component tolerance ≤1mm (the national standard is 3mm); during installation, 3D laser scanning technology is applied to ensure that the assembly precision of complex shapes reaches the 0.5mm level. Take the translucent concrete project at Century Plaza on Nanjing East Road as an example: its UHPC translucent components not only meet the enterprise standard of light transmittance ≥80%, but also passed 12 tests exceeding national standards, including impact resistance and fire protection (Class A1), ultimately winning the "UHPC Construction Engineering Innovation Award Silver Award."

### III. The Responsibility of a Standard Setter: From "Complying with Standards" to "Leading Standards"

As the drafting unit of multiple national and industry standards, including Glass Fibre Reinforced Cement (GRC) Decorative Products, JC/T940-2022, and Ultra-High Performance Concrete (UHPC) Exterior Wall Panels, T/CBMF171-2022, Qinglong Group knows full well that "exceeding national standards" is not merely a corporate act but an industry responsibility. Through the application of 58 patented technologies and continuous innovation at its provincial-level R&D center, practical experience is fed back into standard upgrades: for example, regarding the environmental performance of GRG materials, the enterprise standard requires formaldehyde emission ≤0.01mg/m³ (the national standard is 0.1mg/m³), driving the industry toward green building materials. This cycle of "practice—standard—re-practice" makes enterprise standards a "testing ground" for national standard upgrades.

### IV. Customer Value Orientation: Quality Control as the Core Competitiveness of Solutions

For real estate developers and designers, material quality directly affects project reputation and whole-life-cycle costs. Qinglong Group's above-national-standard control system delivers triple value to customers: first, risk reduction—GRC components pass 20-year durability tests (the national standard is 10 years), reducing later maintenance costs; second, greater design freedom—UHPC's ultra-high strength supports large-span, thin-section designs, meeting the freeform shape requirements of landmark buildings; third, stronger project competitiveness—in strategic cooperation with leading developers such as Poly and Vanke, above-national-standard quality serves as an important endorsement of each project's differentiated advantages.

From the corporate motto of "meticulous in every detail, striving for excellence" to certifications as a National High-Tech Enterprise and a Specialized, Refined, Distinctive, and Innovative Enterprise, Qinglong Group's 28 years of industry experience prove that setting enterprise standards above national standards is not a technical show-off but the practice of its mission to "create beautiful architecture." In the field of new architectural decoration materials, only by holding oneself to more stringent requirements can a company set a benchmark for the industry and create real value for customers.
