Fire doors have wooden fire doors and steel fire doors.
Henan Jutai Door Industry specializes in fire-resistant doors, including steel and wood fire doors, as well as steel fire shutters. As a comprehensive company integrating R&D, manufacturing, sales, and service, it provides high-quality fire protection solutions for industrial and commercial enterprises. Fire doors come in two main types: wooden and steel. While steel fire doors are widely recognized, many consumers still question how wooden fire doors can be fireproof. This is where the flame-retardant treatment of wood plays a crucial role.
The flame-retardant process is essential to ensure that wooden fire doors meet safety standards. However, due to outdated technical regulations and varying practices, different manufacturers apply different methods, leading to inconsistent quality. Some companies may not follow proper procedures, which can reduce the fire resistance performance of the door and pose risks to life and property.
Common flame-retardant techniques include spraying, soaking, boiling, vacuuming, and vacuum pressing. Spraying and soaking are typically used for thin wood sheets (less than 10mm) and are not suitable for producing wooden fire doors. Although vacuum and vacuum press methods offer superior flame resistance, they require expensive equipment, so not all companies use them.
Many fire door manufacturers rely on the boiling method for flame-retardant treatment. At Jutai Door Industry, we emphasize that the moisture content of the wood is a key factor in determining the effectiveness of the flame retardant. Wood that is too wet may not absorb the flame retardant properly, while dry wood can absorb more, resulting in better fire resistance. Studies show that wood with a moisture content below 15% can achieve an oxygen index that is over 5 points higher and a flame-retardant depth that is more than 3mm deeper compared to wood with over 40% moisture.
At Jutai Door Industry, we strictly control the moisture level of the wood before flame-retardant treatment to ensure consistent and reliable performance. Our commitment to quality helps us deliver safe and effective fire doors that meet industry standards.
