Fire doors, as the name suggests, are essential components in fire safety systems. They are designed to prevent the spread of fire and smoke within buildings, offering critical protection during emergencies. Typically installed on firewalls, stairwell entrances, or along pipelines, these doors play a vital role in minimizing damage and saving lives. Fire prevention is not just a task—it's a responsibility that must be taken seriously. But what exactly are the specifications for fire doors, and how much do they cost?
When it comes to fire doors, one of the most important factors is their fire rating. According to the latest standards, the fire resistance of traditional Class A, B, and C doors has been updated to 1.5 hours, 1 hour, and 30 minutes respectively. This adjustment enhances fire protection across the country and offers more options for different applications. For situations where full insulation isn't required, partially insulated or even non-insulated fire doors can be used, depending on the specific needs.
First, the size of fire doors
Fire doors aren’t always standard-sized. While common dimensions include 1500x2100mm, 1200x2100mm, 1000x2100mm, and similar variations with 2400mm heights, many manufacturers can customize sizes based on customer requirements. The standard materials usually include a 1.2mm frame and 0.8mm door panel, filled with perlite for insulation. The door also features a 110mm side width, meeting all necessary fire protection regulations. Options like A, B, and C grades are available, making them suitable for various construction projects.
Second, the price of fire doors
Qualified Grade B wooden fire doors typically start at around 300 yuan per square meter. For steel fire doors, the minimum price (excluding tax) is about 640 yuan per unit, with some reaching up to 740 yuan. Most quotes fall around 680 yuan. Prices vary depending on whether the door is sold as a complete set or by the square meter. For example, stainless steel glass fire doors may cost around 400 yuan per square meter, while high-grade steel A-rated doors can go as high as 270 yuan per square meter. International-standard Class B steel fire doors may cost at least 1,000 yuan, and steel fireproof security doors might reach 1,280 yuan per set. These prices can serve as a general reference when purchasing.
Third, common types of fire doors
Wooden fire doors
These doors are constructed using fire-retardant wood. The wood is treated through vacuum-pressure impregnation for 4 hours, ensuring deep penetration of flame-retardant solutions. The door leaf is made from fire-retardant plywood or high-strength, paint-free boards. Available finishes include Liu Yan, Qu Liu, Sapele, Beech, Cherry, Black Walnut, and Red Walnut, offering both functionality and aesthetic appeal.
The core of the door is filled with environmentally friendly fire-resistant insulation materials, pressed together with eco-friendly adhesives. Sealing treatments are applied at the joints between the door leaf and frame, as well as around fireproof glass, significantly enhancing the door’s fire performance.
Steel fire doors
Constructed from high-quality, zinc-free galvanized steel plates, the frame is 1.2mm thick, and the door leaf is 0.8mm. After degreasing, the surface is sprayed and heat-transferred, preventing rust and maintaining a durable finish. These doors come in various styles, featuring smooth lines and elegant designs that add sophistication to any space. The interior is filled with advanced, eco-friendly fire-resistant and insulating materials, secured with professional equipment and environmentally safe adhesives. Again, sealing treatments at key joints improve fire resistance dramatically.
In summary, understanding the specifications and pricing of fire doors is crucial when making a purchase. Before buying, it’s important to know the exact size you need. Many manufacturers offer custom options, so don’t hesitate to ask. Always choose a reputable brand to ensure quality and reliability. Fire doors are not just products—they’re lifesavers in times of emergency.
