Fire Door Seals for Doors/Windows

To prevent fires and improve building safety and compliance, commercial and residential applications, as well as equipment manufacturers, require high-quality, durable, fire-resistant doors and windows.  All fire doors must be fitted with appropriate fire-resistant sealing strips. Fire door strips and seals tightly fill the gaps between the door and frame, integrating fire resistance, smoke prevention, sound insulation, and sealing functions to effectively block the spread of flames and toxic fumes, buying valuable time for evacuation and property protection.
Guangdong Zhongxiang New Material Co., Ltd. is a custom manufacturer of rubber extrusion and molding products, including custom fire door smoke seals. We can provide fire-resistant and smoke-proof sealing strips suitable for wooden doors, metal doors, and composite doors, offering customized materials and sizes according to your required fire resistance rating, with self-adhesive backing, etc. With decades of experience in the extrusion industry and production capacity, we can provide sealing strip products in various sizes and shapes to meet customer needs and standards, while ensuring on-time delivery.
