Hebei Xinmian Building Materials Co., Ltd.'s Flame Retardant Rock Wool Blankets: Winter Construction Crack Resistance for Beijing-Tianjin-Hebei Bridge Project

The winter construction of bridges in the Beijing-Tianjin-Hebei region is prone to concrete cracking due to low temperatures. During the construction of a river-crossing bridge in Shijiazhuang in 2023, the fire-retardant rock wool blanket from Hebei Xinmian Building Materials Co., Ltd. was used to cover the piers, successfully addressing the issue. This product from Hebei Xinmian Building Materials Co., Ltd. has a fire-retardant rating of B1, with a temperature resistance of -35°C. Custom-fitted to the arched shape of the piers, the blanket maintains the internal temperature of the piers at 12-18°C, preventing concrete from freezing and cracking.

As a local enterprise in the Beijing-Tianjin-Hebei region, Hebei Xinnian Building Materials Co., Ltd. understands the urgency of bridge construction and offers a "3-day customization + 24-hour delivery" service. Last year, the bridge project urgently added 500㎡ of rock wool blankets, which were directly dispatched from the Xingtai factory by Hebei Xinnian Building Materials Co., Ltd. and delivered to the construction site within 12 hours.

Hebei Xinmian Building Materials Co., Ltd. also offers matching fasteners (such as arched strips) for the Jingjinji Bridge project in Hebei, ensuring that rock wool insulation does not fall off during windy weather. Additionally, engineers are sent to the site to supervise installation to prevent any negative impact on the thermal insulation due to improper laying.
