The lack of attention to hardware accessories reduces the firmness and safety of the door and window curtain wall, directly affects the quality of the door and window curtain wall, and brings hidden dangers to personal safety, so special attention should be paid to the safety of hardware accessories. Insufficient understanding of the safety of hardware accessories. In 1999, a fifteenth typhoon in Xiamen, tens of thousands of trees were blown down, electric poles, tower cranes were blown down, more than 20 glass curtain walls and aluminum windows were not blown, many window sashes Was blown off because the hardware is not strong. The sash has a multi-point lock on the four sides of the sash, which is not blown off. The backward situation of door and window curtain wall hardware accessories has existed for many years. It seems that sanitary ware is the same. It knows that backwardness can not be solved. What is the problem? The main importance of the accessories is insufficient. The performance is very low on the surface decoration of hardware. This is a factor that affects development. Do not pay attention to the decorative nature of hardware accessories, hardware accessories are part of the overall window and door curtain wall, the beauty of the appearance is part of the important requirements of the door and window curtain wall. Some people think that hardware accessories can be used on the line, the aesthetic requirements are poor, the common curtains are cheaper, the crescent locks are more, and the upper and lower latch type window locks are more. Insufficient understanding of the use of functional, China's door and window curtain hardware accessories have not changed for a few years, there is no new development in the market, most of the important projects use high-value imported hardware accessories, foreign companies specialize in researching various types of hardware Accessories, so different varieties, different performance hardware accessories emerge one after another, our locks are generally two lock points, foreign production multi-point lock, divided into three points, four points, six points lock, hardware accessories can improve the function of doors and windows, you can make The hardware of sliding the folding door like a car, because of the high-end multi-functional accessories can have multi-function doors and windows. To establish a new hardware factory is a big investment, whether it can be done with foreign manufacturers, joint ventures to set up factories in China, and some domestic military aviation parts factories, because the production of the industry has not enough snacks, you can put advanced idle equipment. There should be no problem in the production of high-end hardware. In short, we must change the backwardness of door and window hardware as soon as possible. Several large and famous hardware parts factories in China are old and not advanced, the scale of the factory is small, and the management is poor. Many of them are township enterprises, and they have not left the workshop. Insufficient understanding of the hardware accessories of the door and window curtain wall, door and window curtain wall hardware accessories everyone admitted to backward, but why no one to develop, some people think that the hardware accessories profit is too thin, not worth investing, and too little investment can not do hardware Therefore, no one has invested a lot in many years, and the hardware accessories have been extended from abroad. The same level of hardware accessories at the same level is much lower than the cost of foreign countries. The whole benefit is not small, but it is very impressive. Hardware accessories, low-grade curtains profit is not high, but high-end profits are not thin, we have studied, foreign hardware accessories profits accounted for 20% to 30% of foreign costs (excluding import taxes) new short-term hardware accessories profit Be high.
