The prices of fire doors with different fire ratings usually vary greatly.

The main reasons include:

1,Material and construction: Fire doors with high fire ratings usually use higher-grade fire-resistant materials and have more complex manufacturing processes, so they are more expensive.

2,Testing and certification: Fire doors of different grades need to pass different fire resistance tests, and the costs of these tests and certifications will affect the final price.

3,Application scenarios: Doors with high fire ratings are usually used in higher-risk places, such as hospitals, schools, etc., so their design and manufacturing standards are also more stringent.

4,Market demand: The market demand for doors with different fire ratings will also affect the price. Usually, the demand for high-grade fire doors is small, so the price is relatively high.
