Saving energy demand plastic doors and windows market industry can seize the opportunity
Last year, China plastic doors and Windows in the town of new residence market share to 55%. Though the proportion is very high, but in fact is down from three years ago, especially in the southern market, plastic doors and Windows market share fell more, when China town in new residence more than 70% use plastic doors and Windows.
On one hand, it is the other door window competitiveness. Around 2000 plastic doors and Windows sprung up, and in the short term to good heat preservation sex, anticorrosion, occupy a lot of traditional aluminum alloy sliding window market, aluminum alloy doors and Windows was almost be compelled a big city say new residence market. But almost a two years, aluminum alloy doors and Windows industry increased research investment, new thermal insulation performance is good high-grade the alloy window, adornment the good performance of color aluminum alloy doors and Windows, heat preservation adornment performance is good aluminum wood doors of the appearance of new products, and make the competitiveness of the aluminium alloy door ask obvious rise, begin to have the capacity and plastic doors and Windows rob market.
On the other hand, is also plastic doors and Windows long-term excess capacity, low quality competition, new product development is slow consequences. Because investment overheating, plastic door window industry since 2003 are in serious excess capacity, fierce competition makes the industry in the mire of the price war, lead to plastic door window quality issue is very outstanding, serious impact on the industry competitive power, and long-term price war more led directly to the new product development is slow. In the fierce competition, not to advance is to go back, plastic doors and Windows to the performance of the industry can hold for it entered. The ministry of construction a officials have made clear PVC folding door industry to the concerns of the creative ability of science and technology. He said that, based on the doors and Windows in building energy saving, the importance of construction ministry this year to the national development and reform commission has proposed funding for Windows and doors single project, he I still tend to make plastic doors and Windows, but find four experts, can put forward the feasible project, a very disappointed. Reference plastic doors and Windows industry mature countries, such as Germany, the plastic doors and Windows industry pattern is roughly a dozen companies and 1000 or so medium-sized enterprise, large enterprises to scale, a high degree of automation and occupy the major markets, medium enterprise with high technology content of a single species to win.
Energy saving aluminium alloy window be careful to choose
Aluminum alloy doors and Windows because of light weight, high strength, good performance, decoration use strong, durable, color diversity economy, no pollution, can recycle and become China’s main building doors and Windows of our products are widely used in public buildings from high-end to the general civil residence and industrial plants. Energy-saving aluminium alloy window of aluminium alloy profile is heat insulation, energy saving and glass, hollow glass, low-e glass, absorption of glass, coated glass, vacuum glass, etc) is made and be become.
When the choose and buy need to pay attention to:
First of all: see material pledge. If the heat insolation aluminum, the main profile is greater than 1.4 mm thick wall to; The same root aluminium alloy profile colour and lustre should be consistent, such as color difference obvious, which is unfavorable to choose; Check the surface of aluminium alloy profile, there shall be no depression or drum out; Aluminum alloy doors and Windows avoid the choose and buy has an open surface bubbles (white) and ash (black spots), and crack, burr, peeling and the obvious flaw profiles; Oxidation film thickness should achieve 10 microns, can be in when the choose and buy the material surface under a light, see its surface oxidation film whether it can be erased.
Next: see quality of manufacture and assembly quality. Door window decoration surface should not have obvious damage, it refers to the surface of the door window should not scratch scratch protective film of trace. The doors and Windows adjacent component surface colouring should not have clear off color. Aluminium folding door should not have the surface of aluminum powder, burr, staining or other stains, assembly joint should not have spillover of the adhesives.
Repeated switch many times, to check whether the power switch overweight; Article seal whether firmly; Hardware assembly is all ready; Casement window frame lap a quantity to whether meet the requirements (standard casement Windows not less than 6 mm, push-pull window not in 8 mm).
Finally: see the glass. If hollow glass, have the coating.
