The prices and specifications of fire doors can vary significantly based on multiple factors, making it crucial for buyers to have a comprehensive understanding before making a purchase. These factors include the type of material used, door size, level of fire resistance, additional features, and brand reputation.

Regarding materials, fire doors can be constructed from steel, wood, aluminum, or composite materials, each with its own price range. Steel fire doors are generally mid - to high - priced. Their durability, strength, and excellent fire - resistant properties justify the cost. For example, a standard - sized, single - leaf steel fire door with a 90 - minute fire - resistance rating may cost between \(500 and \)1,200. Wood fire doors, especially those made from high - quality, fire - treated hardwoods, can also be relatively expensive, ranging from \(600 to \)1,500 or more, depending on the wood species and craftsmanship. Aluminum fire doors are often more affordable than steel or wood, typically priced between \(300 and \)800, offering a good balance of durability and cost - effectiveness. Composite fire doors, which combine the benefits of different materials, vary widely in price, from budget - friendly options starting at around \(200 to high - end models costing over \)1,000.

Door size is another key determinant of price. Larger fire doors, such as those used for industrial or commercial entrances, require more materials and may involve more complex installation, driving up the cost. A double - leaf, extra - wide fire door with a 120 - minute fire - resistance rating could cost upwards of $2,000, while a standard - sized, single - leaf door with the same rating might be half the price. The level of fire resistance also impacts the price. Doors with longer fire - resistance ratings, like 120 minutes compared to 30 minutes, are constructed with more advanced fire - resistant materials and better - engineered components, resulting in a higher price tag.

In terms of specifications, fire doors come in a wide range of sizes to fit different door openings. Standard residential fire doors usually have dimensions such as 30 inches by 80 inches or 36 inches by 80 inches. Commercial and industrial fire doors can be much larger, with widths up to 10 feet or more and heights of 12 feet or higher. Fire - resistance ratings are specified in minutes and can range from 20 minutes for basic fire doors to 180 minutes or more for highly - rated, heavy - duty doors. Additionally, fire doors may have various additional features, such as glass inserts, panic hardware, or self - closing mechanisms. Each of these features can add to the overall cost, but they also enhance the functionality and safety of the door. Understanding the prices and specifications of fire doors is essential for making an informed decision that balances safety requirements with budget constraints.
