In the early 1980 s, aluminum alloy doors and Windows in our country was published, due to its light weight, corrosion resistant, unique advantages of the original replace gradually the favour of steel window by consumer. But in the past two years the domestic window of model steel door development speed quickly, aluminum alloy doors and Windows of the market has been to cause significant impact. Some people think that, aluminum frame coefficient of thermal conductivity of the doors and Windows of strong, adverse heat insulation, heat insulation and plastic, and save energy. According to this view, China architectural decoration association aluminium committee concerned expert thinks, in fact, heat insulation is mainly glass, not the window frame materials.
Since always, window of model steel window usually in a lower houses. This is because, on the one hand, the plastic exists, cracked aging; On the other hand for domestic manufacturing of model steel and steel plates in plastic there is space between, air and water can enter and gradually corrosion steel plate, cannot assure intensity and rigidity. So now a lot of plastic window window frame is not straight, often couldn't pull the and it is difficult to open. And in contrast, aluminum alloy are the unique advantages of the world have been acknowledged, and can be used to produce all kinds of complex profile multifunctional doors and Windows, use fixed number of year can be more than 50 years, or even longer, it is general materials difficult to replace, window of model steel door is cannot match.
In the tech shares of market and foreign aluminum wndows and doors factory is about to enter the market under double pressures, many firms think that consumers give up mainly for aluminum alloy to more and more thin aluminum material not trust, if continue to low quality and low price products seizes the market, will soon be out of the market.
Enterprise to survive, must use a high-tech, speed up the development of new products, as soon as possible to set up his own brand. For example, in order to better than model steel heat insulation, the enterprise can produce heat insulation aluminium alloy profile short bridge, so as to meet the same model steel window and the adiabatic effect. Industry insiders point: the impact of window of model steel door, that domestic enterprise aware of innovation and quality of the necessary; The opportunity of the wto, more let they felt great pressure and challenges. Like the north for aluminum and other large international of aluminum alloy Windows production type materials listed enterprise, as an industry, a key enterprise of this year to go to the quality will be service brand type the expansion of the road, but also aluminum alloy doors and Windows to the development of high technology, high quality for a year.
Window of model steel door, as a kind of new building products, nearly two years in doors and Windows market sprung up, and the market share of more than ordinary greatly wood, steel doors and Windows, color plate doors and Windows, matches the aluminum alloy doors and Windows. More data show that the next century is the world of window of model steel door, at the appointed time, aluminum alloy doors and Windows will be pushed corner, to be washed out ranks. So, window of model steel door and aluminum alloy doors and Windows exactly which is better or worse? We might as well through the following characteristics compared to.
1, sound insulation performance according to data show that window of model steel door of sound insulation performance is much better than aluminum alloy doors and Windows. For example: up to the same noise requirements of building, installation aluminum alloy doors and Windows of the architectural and road to the distance in 50 meters away, and if use window of model steel door can be shorten to less than 16 m.
2, and heat insulation mention heat insulation, we need from the material basis is technical parameters, such as PVC material thermal conductivity coefficient was 0.14, and aluminum alloy is 175. That is to say, in the same conditions, material for heat conduction ability, aluminium is 1250 times of the PVC material. Of course, if made from PVC doors and Windows, energy consumption is, it can be difficult to treat as the same. Because indoor dissipating heat, usually with the roof and floor, walls and doors and Windows relevant. But the scientific research data show that, as average house, also open air conditioning, pack of window of model steel door room with aluminum alloy doors and Windows room than every day more than five degrees power saving.
3, and corrosion resistance of window of model steel door to acid and alkali resistant and other chemical corrosion, so not afraid the pollution of the environment, hydrochloric acid and city of acid rain erosion. And aluminum alloy is different, encounter corrosion easy to cause the surface oxidation, shorten service life.
4, doors and Windows installation performance and service life of window of model steel door self-respect greatly lower than aluminum alloy widows, more because is the overall forming, installation of speed, so that the whole efficiency greatly improved. Service life, the normal life of window of model steel door for 30 to 50 years, lower than the aluminum alloy doors and Windows.
5, the product design and process performance of window of model steel door and aluminum alloy doors and Windows are available as the design requirements of design personnel making cost, push-pull open, on dangerous and arc window, modelling beautiful and easy novel. Window of model steel door surface shading, film coating, can color co-extrusion;
