Hebei Xinnian Building Materials Co., Ltd. Fire-resistant Rock Wool Blanket: Beijing-Tianjin-Hebei Subway Project, Tunnel Fire Resistance Meets Standards

The Beijing-Tianjin-Hebei subway tunnels have stringent requirements for fire resistance and moisture resistance in insulation materials. The Tianjin Metro Line 6 project in 2023 selected the fire-resistant rock wool blankets from Hebei Xinmian Building Materials Co., Ltd., which were a perfect match. This product from Hebei Xinmian Building Materials Co., Ltd. is flame retardant at grade A and also features waterproof capabilities (water absorption rate < 4%). In the high-humidity environment of the tunnel, it maintains stable insulation performance and meets the fire safety inspection standards for subways.

As a local enterprise, Hebei Xinnian Building Materials Co., Ltd. is well-versed in the construction specifications of the Tianjin Metro and can provide flexible rock wool blankets that match shield machines, facilitating rapid installation within tunnels.

The project has purchased 2,500 square meters of products from Hebei Xinmian Building Materials Co., Ltd. The company will deliver the products in batches according to the construction progress to avoid occupying space on-site.

Additionally, the Beijing-Tianjin-Hebei subway project can benefit from Hebei Xinmian Building Materials Co., Ltd.'s "After-Sales Coordination" service, which synchronizes with the contractor's schedule, providing technical support even during night-time construction to ensure the project progresses on schedule.
