Henan Jutai Door Industry is a leading industrial and trade enterprise specializing in the R&D, production, sales, and service of fire doors, including steel-wood composite fire doors, wooden fire doors, steel fire doors, and fire shutter doors. But how do these doors actually prevent fire? While steel fire doors are well understood due to their strong structure, many people still question how wooden fire doors can be fire-resistant. Let’s take a closer look at the process.
The fire resistance of wooden fire doors largely depends on the flame-retardant treatment applied to the wood. However, the flame-retardant process is often overlooked or improperly executed. Many manufacturers treat this as a critical control point, but due to the lack of standardized procedures, the methods used vary widely—especially among companies in Zhejiang. This inconsistency can lead to poor flame-retardant quality, reducing the fire resistance of the door and posing serious risks to life and property.
Common flame-retardant methods for wood include spraying, soaking, cooking, vacuuming, and vacuum pressing. The spraying and soaking methods are typically used for thin wood sheets (less than 10mm thick) and are not suitable for producing high-quality wooden fire doors. Although vacuum and vacuum pressing methods offer better results, they require expensive equipment, which some manufacturers avoid.
Most fire door companies today use the cooking method for flame retardant treatment. According to Jutai Industry, when using this method, the moisture content of the wood is a crucial factor that directly affects the effectiveness of the flame-retardant treatment. Dried wood absorbs more flame-retardant chemicals, which enhances its fire resistance. The higher the absorption, the better the oxygen index and deeper the flame-retardant depth. Unfortunately, many companies overlook this step, using wet or freshly cut wood without drying it first. They mistakenly believe that the moisture doesn’t matter, leading to inconsistent and unreliable results.
Studies show that under the same conditions, wood with a moisture content below 15% can achieve an oxygen index increase of over 5 points and a flame-retardant depth of more than 3mm. This makes a significant difference in performance and safety.
At Henan Jutai Building Materials Sales Co., Ltd., we understand the importance of proper flame-retardant treatment. Our focus is on delivering high-quality wooden fire doors that meet strict safety standards.
