There are many types of fire doors, such as steel fire doors, wooden fire doors, and so on. Literally, we can easily be misunderstood as thinking that steel fire doors have better fire resistance than wooden fire doors, but in fact, they each have their own characteristics. Now let's take a look at the difference between steel fire doors and steel wood fire doors.   & nbsp; Steel fireproof doors are made of steel materials for the door frame, door frame, and door panel, and filled with refractory materials inside the door leaf; Wooden fireproof doors are made of wooden materials as the frame and frame of the door leaf. This is not ordinary wood, but is processed through multiple flame retardant processes to achieve non combustible performance. Its interior is filled with fire-resistant perlite that is non combustible, heat-insulating, and flame-retardant. Due to the coldness of steel fireproof doors, they give people a feeling of oppression in winter. In summer, the already restless and hot mood becomes cool upon seeing them, indicating that home has arrived. Generally, wooden fireproof doors are usually festive and bring a more relaxed mood upon seeing them. So wooden fireproof doors are generally used indoors.
