Carefully manufactured high-quality steel, filled with fireproof material inside, look to implement the latest electrostatic spray, anti-burning, anti-theft, beautiful and durable. Retardant long time, to prevent the spread of fire, cut off the source of fire, for fire rescue time. Insulation, smoke effects, reducing drug charges entry and proliferation, avoid inhalation of toxic smoke and people trapped rapid death. Impact-resistant, long resistant structure from collision, fire effect is not reduced, the disease can withstand the impact of the fire hydrants. Steel double leaf fire door heat deformation rate, low warpage deformation when heated, when the fire escape can be freely opened or closed and smoke evacuation, waiting for rescue. v A class totally insulated fire doors, also known as fire doors, within a specified period of time to meet the fire insulation and fire integrity requirements, fire resistance rating were 0.5h (Class C), 1.0h (as well), 1.5 h (Class A) and 2.0h3.0h. v Class B fire doors, also known as part of the fire door, the fire insulation requirements 0.5h, fire integrity rating was 1.0h, 1.5h, 2.0h, 3.0h. v Class C fire doors known as non-acoustic fire doors, fire insulation does not require it, within a specified time to meet fire resistance requirements for fire integrity only fire integrity rating was 1.0h, 1.5h, 2.0h , 3.0h. The main parameters: Fire resistance: Class of 1.5h, B was 1.0 h, Class C is 0.5 h. Sound effects: With satisfactory sound insulation, sound insulation Class C product RW≥23dB. Decorative: surface electrostatic powder spray, beautiful and strong durability, offers a variety of color choices. 4 fire doors normally closed generally outside the door, open the evacuation direction, stand at the door in the face of the hinge, the hinge is about to open to the outside. 5 installation location, hole size, please provide a floor plan and dimension tables.

The use of similar colors with the same pattern, interpretation of exquisite romantic style, elegance without publicity, elegant and subtle, reason and thanks to achieve blend and fit. Fire-resistant glass doors into steel, wood and stainless steel categories, having properties similar fire doors, but also has good decoration, high transmittance, sound insulation, etc., required to achieve the decorative effect of modern high-rise building The hall, corridor and other places fire separation doors are widely used.
