Steel-wood armored doors are doors that meet specific thermal insulation and fire-resistance requirements. They are primarily used in fire-resistant zones, evacuation routes, electrical distribution rooms, stairwells, pipe shaft openings, and other critical areas, making them essential fire-protection building materials. 1. Steel-wood armored doors are classified into three categories based on their fire-resistance ratings: Class A (90 minutes), Class B (60 minutes), and Class C (30 minutes). 2. Steel-wood armored doors can be either normally closed fire doors or normally open fire doors, depending on their operational status. 3. The internal filling materials of steel-wood armored doors typically include expanded perlite and calcium silicate fire-rated boards. 4. Steel-wood armored doors are equipped with fire-rated seals, fire-rated hinges, door closers, or fire-rated locks; some models also feature fire-rated glass. 5. Domestic manufacturers of steel-wood armored doors must provide type approval certificates and obtain inspection reports from the Fire Product Certification Center of the Ministry of Public Security. They must also comply with the current fire safety regulations, specifically GB 12955-2008. In addition to the standard functions of ordinary doors, steel-wood armored doors possess special fire-resistant and smoke-sealing capabilities. When normal passage is required, Class A fire doors are installed in fire-resistant zones of buildings. Should a building unfortunately catch fire, Class A fire doors can effectively prevent and delay the spread of flames to a certain extent. Fire doors must undergo rigorous testing according to national standards, employing appropriate material selection methods, superior structural design, and reliable fire-performance characteristics. Beyond their critical fire-resistance features, civilian fire doors must also emphasize lightweight construction, aesthetically pleasing appearance, and long-lasting durability. Based on their fire resistance, they are categorized into Class A, Class B, and Class C fire doors; and according to the materials used, they are divided into wooden fire doors, armored fire doors, and composite fire doors.
