Recently, the Hankun? and Keyan? calcium silicate board/fiber cement board series products have officially passed the authoritative testing by SGS and successfully obtained the French A+ certification, thanks to their exceptional quality and outstanding environmental performance. This achievement adds another highlight to the products' export prospects to developed markets in Europe and America!

The French A+ certification is the highest environmental rating certification established by France for indoor building materials. It aims to assess the impact of building materials on indoor air quality and human health during use. A+ represents the highest level within this system, with standards approximately 8 times stricter than China's national standards (GB/T). The TVOC limit is only 1/80 of the domestic standard, and the certification is directly based on actual air quality as the evaluation criterion. Recognized internationally as the top environmental benchmark, it serves as a "passport" to high-end global markets and a symbol of brand strength, often hailed as the "highest medal" in international environmental certifications.

In accordance with the ISO 16000 series standards, this certification involved continuous testing in a sealed chamber simulating real living environments. The tests measured the emission concentrations of ten harmful substances, including total volatile organic compounds (TVOC), formaldehyde, acetaldehyde, toluene, and ethylbenzene. The results for all substances were: ND (Not Detected). This once again verifies the "truly eco-friendly" characteristics of the Hankun? and Keyan? calcium silicate board/fiber cement board series products, which are free from formaldehyde, 100% asbestos-free, and devoid of harmful substances such as benzene.

Hankun? and Keyan? series products are naturally eco-friendly and release no harmful substances. They redefine "health" with the stringent standards of Green Three-Star building materials and achieve "move-in-ready" quality with international A+ grade performance. Suitable for sensitive spaces such as children's rooms, bedrooms, and residences for pregnant women and the elderly, they genuinely eliminate indoor pollution risks at the source. Additionally, with advantages such as fire resistance, moisture-proofing, lightweight yet high strength, easy installation, and reusability, these products are gradually replacing high-energy-consuming and resource-intensive materials in the industrialization of building decoration and the greening of construction materials. This pioneering effort opens up new prospects for the comprehensive application of calcium silicate-based series products in green building initiatives.
