Description: Door frame, door made of imported or domestic high-quality cold-rolled steel, galvanized steel or stainless steel plate manufacturing, filled with temperature above 1200 ℃ high-quality aluminum silicate fiber cotton, surface electrostatic spray treatment, supporting stainless steel fire lock (or Pipe lock), steel galvanized (stainless steel) fire hinges, door closers and so on.
Main technical performance:
1. Fire resistance: Grade A is 1.2h, Class B is 0.9h, Class C is 0.6h.
2. Sound insulation effect: has a good sound insulation effect, C-class products sound insulation indicator RW ≥ 23dB.
3. Decorative: surface electrostatic powder spray, beautiful and durable, providing a variety of colors to choose from.
The direction of the door to determine the opening:
1. Fire doors are normally closed outside the door, open to the direction of evacuation, standing outside the door facing the hinges, hinges in the right for the right to open.
2. The installation location of the door, the size of the hole, please provide the building plan and size table.
Standard hole size:
Steel fire doors are made of cold-rolled steel doors do door frames, door panels, skeleton in the door filled with non-flammable materials, and with the hardware components can meet the fire resistance stability, integrity and heat insulation requirements of the door, fire doors From the level of sub-A, B, C three levels, Class A refractory limit of not less than 120 minutes, B fire resistance greater than 90 minutes from the species can be divided into single open, double open, with glass, with bright windows Type, specifications can be customized according to the hole size processing, live fan maximum size limit of 3 meters high, 1.5 meters wide.
Steel fire doors with beautiful shape, compact structure, surface treatment and color according to the user's preferences, but also after the completion of the installation of the building, the same hole and the cost of fire shutter compared to the advantages of low price, widely used in All kinds of buildings, such as hotels, restaurants, shopping malls, warehouses, hospitals in the fire cut off, evacuation channels, warehouse power distribution room, room and other important parts.In addition with the fire awareness of the masses to strengthen their civilian range is also very wide.
1. Steel fire door frame, door panel and its reinforcement should be cold-rolled steel plate. Door frame should adopt 1.2 ~ 1.5mm thick steel plate, door panel should adopt 0.8 ~ 1.2mm thick steel plate, reinforcement should adopt 1.2 ~ 1.5mm Thick steel plate, reinforcement, such as with a screw hole, steel plate thickness should not be less than 3.0mm.
