Structure adjustment technology innovation to promote the PVC doors and Windows KuMuFengChun
Shortly before the club held in the ministry of construction work meeting, China construction steel structure association conference as a typical in the exchange of experience. This association has the comprehensive enhance enterprises’ independent innovation ability, accelerate industry product structure adjustment, to promote industry technology progress is a top priority to grasp, and actively solve industries and enterprises with the problems, the enthusiasm for industry and enterprise service, the competent departments and enterprises by high praise.
China construction steel structure association to implement state "by steel and wood" policy, using an empty stomach or real abdomen steel window. It can effectively save timber, protect national forest resources. But ordinary carbon steel window corrodes easily, sealing performance is poor, heat preservation, and the developed countries was widely used in has the good performance of plastic doors and Windows, aluminum doors and Windows and building curtain wall. Our country is in urgent need to upgrade its products. The association to lose no time to the ministry of construction, the paper proposed some restrictions, backward steel doors and Windows, the promotion of plastic doors and Windows and aluminum doors and Windows. At present, aluminum, plastic doors and Windows has accounted for 85% of the share, ordinary steel doors and Windows had been choi steel window, stainless steel window of more generation of break hot steel window is under development. Begin from 2003, the association and the European doors and Windows association, American association of Windows and doors, Windows and doors association and the international doors and Windows Russia organization held once a year international fenestration and senior seminar. The fair better, the bigger the technical level more and more high, caused the attention of international industry, has become the second largest trade fair, through the expo promote international technical exchanges.
The association also organization colleges and enterprises from scholars of technology discussion, research, promote the upgrading of the industrial structure adjustment and products. The aluminum door window curtain wall insulation performance is poorer, the association organization experts successfully developed the break hot aluminous window profile, energy saving effect is very obvious, the heat transfer coefficient K value from 6.4 to 2.98, in the aluminum door window curtain wall industry spread rapidly.
Curtain wall industry late start, high starting point, fast development, the production enterprise with 3000 home, the output value is as high as 100 billion yuan. The unit curtain wall, some arguments take curtain wall, double channel, curtain wall, single cable and network cable type curtain wall, photoelectric curtain wall, curtain wall, intelligent, novel structure, walls bright beautiful, both can satisfy the different style of the building structure design requirements, and also can save energy, beautify the city. After more than ten years of effort to make our country construction steel structure industry realize the leaping development, now the new construction steel structure, building door window curtain wall, heating radiator, construction drainage equipment, water fountain, has become China’s modern architecture culture, architecture art important symbol, shorten the gap with foreign advanced level, some products reach the international advanced level of the same products, improve the quality and performance of the house. The national various cities large landmark, of the Beijing 2008 Olympic Games all sports venues of steel structure, curtain wall and door window is almost the member of the enterprise production installation, the people’s great hall of the outside the window also to replace, the association has organized an expert discussion and argument many times.
This association leaders at various levels often deeply research enterprise, the industry in time of problems existing in the relevant government departments to reflect, and puts forward some proposals for enterprise development of custom.
A few years ago, steel structure enterprise reflects the existence of double taxation (to pay value added tax, the enterprise is to be located to the enterprise construction installation to pay business tax), the association have held enterprise symposium, feel is more serious, double taxation increased the burden of enterprise, bound by the development of the enterprise. Association asked for a wide range of opinion, in enterprise seriously on the base of investigation, in time to the finance ministry and the state administration of taxation report, put forward some Suggestions. The state administration of taxation after investigation to verify the research, accept the society’s suggestion, the official dispatch cancelled double taxes of practice. The move to get steel structure enterprise’s consistent high praise.
In the past two years, China’s plastic doors and Windows enterprise too fast development, profile capacity of 3 million tons, but the actual demand for 1.3 million tons only, for far greater than for, as the oil price rise, products such as large and PVC prices falling, the enterprise has no profit, small and medium-sized manufacturers closed many, several large manufacturer also is difficult to support, the development of the industry in the past two years as a prominent long-standing problems. Association to many times, about the whole industry of the two big manufacturers and other backbone enterprise leaders please to together, to coordinate views agree, and puts forward the specific measures to restrain the price.
After the association seriously coordination, the second half of last year, the enterprise has basically stopped in the behavior that price, the product can price controls in the basic guarantee of the development of the enterprise normal level. PVC sliding doors and Windows market situation began to change, the industry and show the vitality, continue to move in the direction of the stable and healthy development.
