Product Description
All fire doors from Xuan Yuan have passed the national standard testing and are rigorously controlled—whether in design, production, or after-sales service—under the ISO 9001 quality management system. Application areas include industrial electronics plants, pharmaceutical and chemical facilities, office buildings, hotel apartments, hospitals, and other venues, where these doors play a critical role in containing fire spread and smoke diffusion during a fire, significantly helping to minimize fire-related losses.
