Aluminum alloy doors and Windows and the contrast of window of model steel door: |

1. Corrosion resistance: aluminum alloy meet after corrosion is easy to cause surface oxidation, shorten service life. Of window of model steel door to acid and alkali resistance and other chemical corrosion, therefore, not afraid of the urban environment pollution, such as hydrochloric acid and acid rain erosion.

2. The sound insulation effect. In aluminum alloy four peripheral sealing strip, can effectively reduce acoustic resonance effect, prevent the transmission of sound, more than 30 db can reduce the noise. Sound insulation effect is better than plastic door.

3. The design process performance. Window of model steel door and window of aluminium alloy door can be produced according to their own requirements on cost drive, push and pull, suspension and arc window, novel modelling beautiful generous. Window of model steel door surface can be colored, laminating, multicolor co-extrusion; Aluminum alloy doors and Windows surface spraying, electrophoresis, color also can be diverse.

4. The heat preservation effect. Plastic material coefficient of thermal conductivity is 1/1250 of the aluminum alloy, steel, 1/357 of the same two rooms, the room of window of model steel door, about 5 ℃ higher than aluminum alloy in the winter, in summer and low 5 ℃ or so, energy-saving effect is very obvious.

5. The service life: aluminum alloy on the hardness of the door is higher than the plastic door. Plastic door because it is the overall forming, installation fast, thus make the whole work efficiency greatly improved. But as a result of plastic door easy to aging, therefore, the service life of the lower than that of aluminum alloy doors and Windows.
