The difference between steel fire doors and wood fire doors lies in their frames and door leaves: the frame and door leaf of a steel fire door are made of steel, while those of a wood fire door are made of wood. The internal filling materials of the two types of doors are essentially the same. Currently, 99% of fire doors available on the market are either steel fire doors or wood fire doors. Most interior doors in buildings are wood fire doors, whereas most exterior doors are steel fire doors. You can choose a fire door based on your specific needs and the required fire rating.

Steel fire-resistant rolling shutter door

2025-03-30

Fire-resistant rolling shutters are fire- and heat-insulating devices suitable for larger openings in buildings. The product features a compact and well-designed structure with the roll mechanism concealed within the shutter itself. Fire-resistant rolling shutters are widely used as fire barriers in both industrial and civil buildings. They can effectively prevent the spread of fire, safeguarding lives and property, and have become an indispensable fire protection facility in modern construction. These shutters are movable fire-separating devices typically made from metal sheets such as steel plates, assembled by means of clasps or hinges. Normally, they are rolled up and stored in a shaft housing above doorways and windows. In the event of a fire, they are lowered and unfurled to block the spread of flames through doorways and window openings. Fire-resistant rolling shutters are essential components of modern building fire protection systems.

Steel Fire-Resistant Doors 1. The door frame is made of 1.2mm high-quality imported zinc-free galvanized steel sheet, while the surface panel of the wooden fire-rated door leaf is made of 0.8mm high-quality imported zinc-free galvanized steel sheet. After degreasing, the product’s surface is coated with plastic powder and then heat-transferred, ensuring it will never rust. 2. The product’s exterior features a variety of standardized patterns with distinct characteristics. Its uniquely designed, flowing lines enhance the overall aesthetic appeal of the product, highlighting its dignified and fashionable features. The interior of the door leaf is filled with a new environmentally friendly, flame-retardant, and heat-insulating material. This material is precisely shaped using specialized equipment and bonded with eco-friendly adhesives in concave and convex areas on the door surface—a technology that is unique nationwide. At the junction between the door leaf and frame, as well as around the fire-resistant glass, fire-sealing treatments are applied, significantly enhancing the door’s fire-resistance performance. Wooden Fire-Resistant Doors 1. The door frame and door leaf skeleton are made of flame-retardant wood from Zhejiang fire doors. The wood undergoes vacuum-high-pressure flame-retardant impregnation for 4 hours, ensuring complete penetration of the flame-retardant liquid and delivering outstanding flame-retardant performance. The surface panel of the door leaf is made of flame-retardant plywood or high-strength flame-retardant lacquer-free boards, available in various finishes such as eucalyptus, elm, sapele, beech, cherry, black walnut, and red walnut. 2. The interior of the door leaf is filled with a new environmentally friendly, flame-retardant, and heat-insulating material, which is bonded together using eco-friendly adhesives. At the junction between the door leaf and frame, as well as around the fire-resistant glass, fire-sealing treatments are applied, greatly enhancing the door’s fire-resistance performance.
