—— TRENDRAY Becomes a Formulator of Industry Technical Standards, Leading a New Era in Polycarbonate Panel Curtain Wall Applications
On June 1, 2025, the "Technical Specification for Polycarbonate Hollow Panel Curtain Wall" (T/CECS 1851-2025), approved by the China Association for Engineering Construction Standardization, officially came into effect. This standard is China's first systematic technical specification specifically dedicated to polycarbonate hollow panel curtain wall engineering, filling a long-standing gap in this field. TRENDRAY, as one of the participating compilation units, is proud to announce that our founder Mr. Wu Zhou is listed among the principal drafters, marking TRENDRAY's formal entry into the ranks of industry standard formulators for polycarbonate panels.
I. Standard Background: Filling an Industry Gap, Regulating Technical Applications
Polycarbonate (PC) hollow panels have been increasingly adopted in building curtain wall applications in recent years, thanks to their excellent light transmittance, impact resistance, weather durability, and lightweight properties. However, for a long time, China lacked a dedicated systematic technical standard for polycarbonate hollow panel curtain walls. The absence of unified specifications for design, construction, and acceptance has constrained the healthy development of the industry.
The introduction of the "Technical Specification for Polycarbonate Hollow Panel Curtain Wall" (T/CECS 1851-2025) directly addresses this industry pain point. The specification was chiefly compiled by China Zhongyuan International Engineering Co., Ltd. and Beijing Construction Engineering No.4 Construction Co., Ltd., reviewed by the Building Industrialization Branch of the China Association for Engineering Construction Standardization, approved for release on March 6, 2025, and officially implemented on June 1, 2025.
The specification comprises 9 chapters, covering general provisions, terms, materials, architectural design, structural design, fabrication, construction, project acceptance, and operation & maintenance, providing full-lifecycle technical guidance for polycarbonate hollow panel curtain wall projects from design through operation.
II. TRENDRAY's Participation: National-Level Recognition of Technical Strength
In the compilation of this standard, TRENDRAY was listed alongside top domestic research institutions such as Tsinghua University Architectural Design and Research Institute Co., Ltd., Tongji University Architectural Design and Research Institute (Group) Co., Ltd., and Southeast University Architectural Design and Research Institute, as well as internationally renowned enterprises including Germany's RODECA GmbH.
Our founder Mr. Wu Zhou was listed among the principal drafters, together with experts from the chief compilation units, major design institutes, and universities, participating throughout the technical deliberation and clause formulation process.
This honor reflects TRENDRAY's years of dedicated technical accumulation in the polycarbonate panel field. Located in Yuyao City, Zhejiang Province, the company operates a production base covering over 10,000 square meters with 15,000+ square meters of standard factory space, achieving an annual production capacity of over 16,000 tons. The company has imported Italian OMIPA production lines and utilizes world-renowned imported raw materials from SABIC and former German Bayer (Covestro). Our products are widely used in large-scale building curtain walls, stadium roofs, and interior decoration projects.
III. Profound Significance: The Leap from "Participant" to "Rule Maker"
Mr. Wu Zhou's participation in drafting the national industry standard carries multiple far-reaching implications for TRENDRAY and the entire polycarbonate panel industry:
1. Establishment of Technical Discourse
Participating in industry standard formulation means TRENDRAY's technical approaches and product concepts have been incorporated into national-level technical norms. The company's practical experience in polycarbonate hollow panel raw material performance, processing technology, and installation techniques has been directly translated into industry-wide technical standards. This represents the highest recognition of TRENDRAY's technical capabilities and grants the company technical discourse power in future market competition.
2. Leap in Brand Credibility
As a standard formulating entity, TRENDRAY's products and services naturally carry dual endorsement of "compliance" and "advanced technology." When customers choose TRENDRAY, they are choosing products that meet the latest national technical specifications, significantly enhancing trust from downstream engineering parties, design institutes, and end users.
3. Construction of First-Mover Market Advantage
Following the standard's implementation, the design, construction, and acceptance of polycarbonate hollow panel curtain wall projects must comply with T/CECS 1851-2025. As an "insider" and "formulator" of the standard, TRENDRAY can promptly adjust R&D directions and optimize production processes to ensure product performance precisely matches standard requirements, thereby securing first-mover advantage in market competition.
4. Shouldering Industry Leadership Responsibility
The standard's release will drive the polycarbonate hollow panel curtain wall industry from "unregulated growth" toward "standardized development." Through participation in standard formulation, TRENDRAY has not only elevated its own industry standing but also assumed responsibility for leading industry technological progress and ensuring engineering quality and safety, demonstrating corporate social commitment.
5. A Bridge for International Cooperation
The participating compilation units included international enterprises such as Germany's RODECA GmbH, making the standard formulation process a bridge for Sino-foreign technical exchange. TRENDRAY seized this opportunity to further align with international advanced technical standards, laying a solid foundation for products to enter overseas markets.
IV. Standard Highlights: TRENDRAY Wisdom Embedded in Technical Norms
In T/CECS 1851-2025, multiple technical requirements incorporate TRENDRAY's practical experience:
Material Performance Requirements: The specification establishes clear requirements for key indicators of hollow panel raw materials, including tensile yield strength (≥60MPa), tensile elastic modulus (≥2200MPa), and flexural strength (≥60MPa), which align closely with TRENDRAY's high-performance product positioning.
Processing Precision Control: The specification details requirements for hollow panel processing dimensions and quality, including permissible deviations for length, diagonal difference, thickness, and edge straightness. TRENDRAY's advanced production lines and quality control systems provided practical basis for the formulation of these clauses.
Construction and Installation Standards: The specification proposes requirements for dry construction methods, reliable connection of fasteners, and reservation of deformation gaps, with TRENDRAY's installation experience from numerous large-scale curtain wall projects providing important reference for the standard.
V. Future Outlook: Driving High-Quality Industry Development Through Standard Power
The release and implementation of T/CECS 1851-2025 marks the entry of the polycarbonate hollow panel curtain wall industry into a new stage of standardized development. TRENDRAY will take this participation in standard formulation as a new starting point, continuing to uphold the development philosophy of "technological innovation, quality first," and persistently strengthening efforts in the following areas:
Technology R&D: Increase R&D investment, continuously optimize product performance, and promote the application of polycarbonate panels in more high-end building scenarios;
Standard Leadership: Actively participate in the formulation and revision of more national and industry standards, contributing TRENDRAY wisdom to industry technological progress;
Quality Assurance: Strictly implement technical specifications such as T/CECS 1851-2025 to ensure every product withstands engineering inspection;
Service Enhancement: Leverage standard norms to provide customers with full-process technical support from design consultation and product supply to installation guidance.
[Conclusion]
Standards are the cornerstone of quality and the beacon of industry development. Mr. Wu Zhou's participation in drafting the "Technical Specification for Polycarbonate Hollow Panel Curtain Wall" is not only a personal honor but also an important milestone in TRENDRAY's corporate history. Standing at this new height, TRENDRAY will continue to be driven by technological innovation and guided by industry standards, contributing greater strength to the green, safe, and high-quality development of China's building curtain wall industry!
