The price of steel fire doors is moderate, but they are heavy, hard to open, monotonous and not beautiful, so they are mostly used in industrial buildings and general grade civil buildings. Wooden fire doors have light deadweight, flexible opening and closing, good decorative appearance and many patterns, but their prices are high, and they are mostly used in middle and high grade civil buildings or important occasions in buildings.
