Industry people know that all kinds of metal elements made of aluminum plus all kinds of alloys with other materials can not match the advantages of light weight and high strength can be squeezed into the various periods of the cross section with a variety of new and complex materials.
experts predict, although in recent years in the low end products, aluminum doors and windows under the impact of weak market performance, but the future is driven by real estate development, due to the corrosion resistance of aluminum alloy doors and windows, variant small amount of fire resistance strong, and long service life, environmental protection and energy saving features, to determine its future is still on the market mainstream.

aluminum windows and doors in the early 20th century, 80 come in our country, because of its light weight,communication products design, corrosion and other unique advantages gradually replace the original steel window by consumers of all ages. But over the past two years
fast development of the domestic steel doors and windows, aluminum doors and windows has caused significant impact on the market.
was expressed that the thermal conductivity of aluminum door and window frame strong, negative thermal insulation and the plastic insulation, can save energy.
for this argument, China Building Decoration Association, Committee on the experts believe that aluminum, in fact, insulation is mainly glass, rather than the frame of the material.

has been generally used in low-rise steel residential windows.
This is because,product design Los Angeles, on the one hand there is the plastic aging, cracking and other problems; the other hand, due to the domestic manufacture of steel in the gap between plastic and steel, air and water can enter and eroding steel, can not guarantee the strength and stiffness.
plastic window frames so that many are not straight, and often difficult to pull them open.
contrast, the unique advantages of aluminum has long been recognized worldwide, can be used for the production of complex multi-functional cross-section windows and doors, use the period of more than 50 years, or even longer, is generally difficult to replace materials, steel doors and windows is second to none.

in the steel market and foreign aluminum doors and windows to seize the plant is about to enter the market under the dual pressures, many companies that give consumers more and more aluminum is mainly out of thin aluminum material is not assured, if it continues to lower quality , low-priced products to seize the market, the market will soon be eliminated.
business to survive you must help of high technology and accelerate the development of new products as soon as possible create their own brand.
example, to heat than the steel, the enterprise can produce short-bridge insulated aluminum profiles, so as to achieve the same insulation and the role of PVC windows.
industry pointed out: the impact of plastic doors and windows, so that domestic enterprises have realized the need for innovation and quality; WTO opportunities, leaving them to feel the enormous pressure and challenges.

steel doors and windows as a new building products,medical equipment design, windows and doors market in the past two years, the sudden emergence of a market share much more than ordinary wood, steel doors, windows, doors and windows color plates, almost equal to aluminum doors and windows.
more data show that in the next century will be the steel doors and windows of the world, then, aluminum doors and windows will be relegated to a corner, into the ranks of being eliminated.
then, steel doors and windows and aluminum doors and windows in the end one is better it?
1. noise performance, according to data indicate that the noise performance of steel doors and windows is much better than aluminum doors and windows.

example: to achieve the same noise requirements of the building, installation of aluminum windows and doors of the building and distance from major roads to be 50 meters away, if you use the plastic doors and windows can be reduced to 16 meters or less.

2.
insulation
mentioned insulation, we need to compare from the material basis of technical parameters, such as PVC, the thermal conductivity of 0.14, while aluminum was 175.
other words, under the same conditions, in terms of capacity on the material thermal conductivity, aluminum is 1250 times the PVC material.
course, if the windows and doors made of PVC, compared to energy consumption, it is difficult to generalize. because the interior heat loss
, usually with roof, floors, walls and windows related.
but scientific information shows that, as an ordinary house, the same open air conditioning, installed steel doors and windows of the room, the room than the aluminum windows and doors installed electricity to more than 5 degrees per day.

3.
corrosion resistance
steel doors and windows to acid and alkaline and other chemical corrosion, it is not afraid of urban environmental pollution, the erosion of hydrochloric acid and acid rain.
the aluminum is not the case, the case of corrosion prone to surface oxidation and shorten life.
