One、What is the material of steel fireproof windows?
Steel fireproof windows are windows that use steel as the frame and are designed to meet fire resistance requirements, including fire stability, fire integrity, and thermal insulation, within a specified time period.
Two. What are the characteristics of steel fire-resistant windows?
1、The window frame and frame are made of steel, which provides sufficient strength to ensure the integrity and stability of the components.
2. The steel frame and stiffeners can be made from galvanized steel or stainless steel. The material selection criteria comply with the requirements of Clause 5.1 of GB12955 "General Technical Conditions for Steel Fire-Rated Doors."
3. The filling material within the steel frame should be made of non-combustible materials.
4. Fire-resistant glass can be selected from products that have passed fire-resistant glass performance tests without compromising the fire-resistant performance of fire-resistant windows. The glass transparency should not be less than 75% of the same-level ordinary flat glass.
5、The sealing material between the frame and the fire-resistant glass should be made of non-combustible materials that can provide fire and smoke protection during a fire.
6. All hardware accessories must be certified and compatible products.
