Product Introduction
Steel fireproof Windows are generally composed of steel window frames, steel sashes and fireproof glass. Windows that can isolate and prevent the spread of fire, and can meet the fire stability, fire integrity and heat insulation in a certain period of time are generally set in the openings on the exterior walls of buildings with insufficient fire spacing or on the firewalls or fire partitions in the buildings that need to be observed and other parts, as well as the openings on the exterior walls that need to prevent the vertical spread of fire.
● Fireproof window fire performance classification and fire grade code:
| Classification of fire resistance | Fire rating code | Fire resistance |
| Fire insulated Windows (A) class | A0.50(Class C) | Fire insulation ≥0.50h, and fire integrity |
| A1.00(Category B) | Fire insulation ≥1.00h and fire integrity ≥1.00h | |
| A1.50(Grade A) | Fire insulation ≥1.50h and fire integrity ≥1.50h | |
| A2.00 | Fire insulation 22.00h and fire integrity ≥2.00h | |
| A3.00 | Fire insulation 23.00h and fire integrity ≥3.00h | |
| Non-insulated fire window | C0.50 | |
| C1.00 | Fire integrity ≥1.00h | Fire integrity 0.50h |
| C1.50 | Fire integrity ≥1.50h | |
| C2.00 | Fire integrity ≥2.00h | |
| C3.00 | Fire integrity ≥3.00h |
● Meet the requirements of "fire window" GB16809-2008:
1. The window frame shall be steel frame or wood frame with a certain strength that is sufficient to ensure the integrity and stability of the component. 2. Galvanized steel plate or stainless steel plate can be selected for steel frame and laminate.
3. The filling material inside the steel frame should be non-combustible material.
4. Fireproof glass can be selected without affecting the fireproof window fire resistance test qualified products. The transmittance of the glass is not less than 75% of the ordinary flat glass with the same number of layers. 5. The sealing material between the frame and the fireproof glass should be inflammable material, which can play the role of fire prevention and smoke insulation in the case of fire.
6. Hardware accessories should be tested and qualified as matching products.

● Function classification:
Fixed fire window (G): fire window without opening the sash.
Movable fire window (H): a fire window with an openable sash and equipped with a sash and opening and closing control device, the sash opening and closing control device has the function of manually controlling the opening and closing of the sash, and at least has the function of automatically controlling the closing of the sash with fusing alloy parts or ball sensing elements, and the electric control mode can be added.
