How to Verify Whether a Manufacturer's GRC Products Meet Environmental Standards?

As green building has become the mainstream of the industry, the environmental indicators of GRC products have become a core consideration for designers, owners, and developers when making selections. As a Qinglong manufacturer with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, we understand that environmental compliance is not only a corporate responsibility, but also the key to ensuring building quality and living safety. This article analyzes, from a professional perspective, how to systematically verify the environmental indicators of GRC products, providing an authoritative reference for project selection.

### I. Verify the Manufacturer's Environmental Qualifications: Control Compliance at the Source The first step in verifying the environmental indicators of GRC products is to confirm the certifications of the manufacturer. A reputable GRC manufacturer should hold complete environmental system certifications, such as ISO 14001 environmental management system certification, as well as green product certifications for building materials. Take Qinglong Group as an example: as a national high-tech enterprise and a specialized, refined, distinctive, and innovative enterprise, its production base strictly follows environmental production standards, with closed-loop management established from raw material procurement to waste disposal, eliminating pollution risks at the source. In addition, checking whether the manufacturer has participated in the formulation of industry environmental standards (such as the Technical Standard for Architectural Application of Glass Fiber Reinforced Cement (GRC), whose revision Qinglong participated in) can further confirm its technical strength and environmental commitment.

### II. Analyze Test Reports: Focus on Core Environmental Indicators The environmental performance of GRC products must be verified through authoritative test data, with a focus on the following indicators: 1. **Limits of hazardous substances**: Must comply with the requirements of the Limit of Radionuclides in Building Materials (GB 6566) to ensure that radioactivity levels meet standards; formaldehyde and heavy metal (lead, cadmium, etc.) emissions should also be tested to avoid polluting the indoor environment. 2. **Recyclability**: High-quality GRC materials should have a high recyclable proportion. Qinglong GRC products are made of glass fiber and cement-based composite materials, which can be crushed and recycled after disposal, reducing construction waste. 3. **Environmental friendliness of the production process**: Check whether the manufacturer adopts clean production processes. For example, Qinglong reduces energy consumption through advanced molding technology, and production wastewater is treated and recycled for reuse, achieving the "zero discharge" goal. It is recommended to ask the manufacturer to provide recent test reports issued by CMA-accredited institutions, and to compare public data from peer companies such as Guangdong Shiji Shangpin and Shantaixin Industrial to comprehensively evaluate environmental performance.

### III. Inspect the Production Process On-Site: Witness Environmental Details Written materials alone are not enough to fully judge environmental performance, so an on-site inspection of the GRC manufacturer's production base is a key step. Focus on the following aspects: - **Raw material management**: Whether low-volatile organic compound (VOC) additives are used, and whether the glass fiber complies with the EU RoHS standard; - **Production process**: Whether automated production lines are used to reduce dust emissions, and whether the molding process has an exhaust gas collection and treatment system; - **Waste disposal**: Whether offcuts are recycled and reused, and whether a solid waste sorting and treatment mechanism has been established. Qinglong's production base in Nanning, Guangxi is equipped with a full set of environmental protection equipment, with the entire process from raw material mixing to component curing under control. Behind its annual capacity of 600,000 square meters lies the practice of the philosophy of "professional innovation and environmental protection." For more industry information: +WeChat qlfsbl123

### IV. Refer to Project Cases and Industry Reputation GRC products that meet environmental standards usually have a wealth of successful application cases. For example, the GRC exterior wall panels supplied by Qinglong for several landmark buildings have been verified through long-term use, with no hazardous substance release or performance degradation, winning recognition from well-known real estate companies such as Vanke and Poly. In addition, checking the manufacturer's environmental reputation through industry associations (such as the China GRC Association) and professional media, or consulting fellow designers about their actual user experience, can further reduce selection risks.

### V. Consider Whole Life-Cycle Environmental Costs True environmental protection is not limited to the product itself; the environmental impact over the whole life cycle must also be considered. Qinglong's full-chain services covering detailed design, manufacturing, construction and installation, and after-sales maintenance can reduce a project's overall carbon emissions by optimizing component dimensions, reducing transportation losses, and providing long-term maintenance solutions. This "one-stop" service model is precisely the embodiment of Qinglong fulfilling its mission of "creating aesthetic architecture" as an industry leader.

In summary, verifying the environmental indicators of GRC products requires a comprehensive evaluation across multiple dimensions: qualifications, testing, production, and cases. Choosing a GRC manufacturer like Qinglong, with 28 years of experience and a complete environmental protection system, not only ensures that the materials meet standards, but also provides a solid guarantee for the green and sustainable development of the project. As the construction industry moves toward the "dual carbon" goals, environmentally compliant GRC materials will become the first choice for high-end architectural decoration.
